Python in actionscript
Hi there,
Total forum newbie here -- apologies if this post is
mischaracterized.
We're working on way to call a Python script via Flash Lite
or embed it inside a Flash application. Is there an easy way to
just call it from within actionscript?
Thanks.
you can use loadVariables() or loadVariablesNum() from flash
lite to call server-side script

Using Ruby in place of Actionscript
I love flash (design tools, stage / layout concepts, etc.),
but I hate actionscript. I've been a programmer for about 10 years
now, programming in everything from C to C#, java, php, perl, ruby,
and actionscript. Actionscript is by far my least favorite of the
group. It is a clumsy language (just have a look at the way
actionscript 2 handled method closures on callbacks) and I'd prefer
to use another scripting language in place of it for my flash
development. Ruby would be an excellent replacement, offering
everything actionscript has to offer (object oriented, event
handling, etc.) with a number of additional features that come
through ruby core and the ruby gems (excellent date and time
libraries, database libraries, file handling libraries, etc.).
Does anyone with an in-depth knowledge of actionscript and
flash know what it would take to achieve some sort of common
language API that would allow such a substitution? If the ruby on
rails guys came across a solution allowing them to leverage the
benefits of ruby (superior language to actionscript) with the
benefits of the flash platform (superior visual control to
html/ajax), flash would be unstoppable.ryanmohr,

Again, fair enough. :) On the other hand, regarding the
missing String
manipulation utilities ...

... hey, if all it takes is five minutes of someone's time,
why not craft
together a utils library and share it? You could make a
positive
difference. :) In that line of thinking, it's not even the
size that
matters. Moses Gunesh, for example, put together an elaborate
and popular
tweening engine, Fuse (
http://www.mosessupposes.com/Fuse/),
and shared the
wealth. Note: by proximity to a casual statement on a String
utils class,
I risk implying that Fuse is just a five-minute exercise in
simplicity,
which is not *at all* the case. I'm only pointing out that
good libraries
can make a helpful difference in people's workaday lives. If
the
functionality you want isn't available, roll your own! :)

Even if I do "appear to be very knowledgable ... [on] the
inner-working
of Flash itself," I don't claim to know much on the
inner-working of Adobe.
I guess it depends on one's point of view -- and to my point
of view,
ActionScript keeps getting better and better.
I think there's more than just taste to consider. For the
type of
programming I like to do -- where the end result is (ideally,
to me) making
cartoon characters move in response to user input, Ruby might
leave me dry
(Flash is strongly suited to vector graphics, sound effects,
video footage,
etc.). My multimedia career started with Macromedia Director,
whose
programming language is Lingo, a very AppleScript-like
language. My guess
is that you wouldn't much care for it at all. From there, I
moved,
reluctantly at first, to Flash, where my programming skill
grew in-step with
the increasing maturity of ActionScript. There was a time,
essentially AS1,
when ActionScript was practically identical to JavaScript,
and I enjoyed
getting to know both. JavaScript led me to regular
expressions, which
fascinated me for fully two years before I got any good at
it. I'm pleased
as punch that AS3 supports regex natively. AS2 brought the
"class"
keyword -- and OOP in general -- to the forefront of my mind,
which led to
brief excursions into Java and C#. I've played a bit with
Python, PHP, and
a handful of other languages. To a certain extent,
programming is
programming: it's the syntax that changes, not the challenge
and fun of
problem solving within a given set of constraints (like the
language
itself). In that regard, it doesn't really matter to me what
language I'm
using, so much as a general answer to the question, "Does
this platform
allow me -- encourage me -- to participate in the kinds of
projects I like?"
Even if I found another language, such as Ruby, more
convenient, it might
not facilitate the sorts of projects I enjoy. To go out on a
limb and make
an extreme example, Ruby, for all its elegance, wouldn't help
me if I had a
passion for programming LCD wristwatches. Because I "grew up"
on
ActionScript, I also have something of a nostalgia for its
particular
quirks. I personally happen to find ActionScript more
palatable than
Lingo -- so I can see some of your points.

I don't know if you consider me one of those who adamantly
supports AS3
or not, and it doesn't really matter. You yourself said that
ActionScript
isn't a bad language -- only that Ruby, in your estimation,
is that much
better. Well, good! I'm glad you've found a language that
pleases your
palate. :) If you were to change your mind and decide, after
all, that
ActionScript actually is a "bad language," it wouldn't be any
skin off my
nose. See, if I step away from ActionScript toward something
else, it means
I'm stepping away from a platform that has continued to
intrigue me for
eight years. If ActionScript were still where it was in the
Flash 4 days,
I'd probably be whistling a different tune. ;)

How can I convert an ActionScript 2 website to ActionScript3?
I have a website which currently uses Action Script 2.
When I change the Publish settings from Flash 7 to Flash 9
and from ActionScript 2 to ActionScript 3, then publish the file, I
get the following warning:
WARNING: Actions on button or MovieClip instances are not
supported in ActionScript 3.0. All scripts on object instances will
be ignored.
What can I do to correct this error?
Is there a simple tutorial that explains how to make the
changes?
I subscribe to Lynda.com but I haven't seen useful there.
I should warn you that I am a beginner when it comes to
coding.
Thank youHi NickLW,
In AS3 there's (like the error mentions) no attaching script
to
instances directly. You probably have something like:
on(release){
gotoAndPlay( 5 );
well, atleast the "on( something )" part...
That's a nono in AS3.
You'd have to change it to code in a keyFrame in the timeline
like:
my_btn.addEventListener( MouseEvent.CLICK, onClick );
function onClick( e:MouseEvent )
gotoAndPlay( 5 )
where my_btn is the instancename of the button.
Look for migration from as2 to as3 in available resources
(like:
http://www.mandalatv.net/fcny/)
Sure there's no mention on the Lynda courses?

Unable to capture stdout, stderr from python.
I am trying to read the stdout and stderr of a python program.
When I invoke anything else apart from python my class works fine.
The python program takes ca 1 sec to start. It then prints one line of text, then it prints a promt and waits for input from user.
I tryed with another program that behaves in the same way and there I got the first line. Not the prompt, that not a python but a native C program.
I have tried using BufferedReader but without sucess.
My class looks like this.
import java.io.BufferedInputStream;
import java.io.IOException;
import java.io.OutputStream;
public class Executer extends Thread {
//read standard out output of the external executable
//in seperate thread to avoid I/O deadlocks
final int BUFFER = 2048;
Process p;
BufferedInputStream in;
OutputStream out;
StringBuffer strbuf;
String[] cmdarr = null;
public Executer(String path) {
this.cmdarr = new String[] { path };
public Executer(String[] path) {
this.cmdarr = path;
public void run() {
try {
System.out.println("doing call");
p = Runtime.getRuntime().exec(cmdarr);
in = new BufferedInputStream(p.getInputStream());
strbuf = new StringBuffer();
out = p.getOutputStream();
int i;
byte[] buf = new byte[BUFFER];
String str;
while ((i = in.read(buf, 0, BUFFER)) != -1)
System.out.write(buf, 0, i);
} catch (IOException e) {
e.printStackTrace();
public int killProcess() throws InterruptedException {
p.destroy();
try {
in.close();
System.out.println("Closed");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return p.waitFor();
}Any ideas is appreciated.When Runtime Exec Won't - a good article on running processes from a Java program...

Can't access object using "id" or "name" if created with actionscript
How can you register an instance of an object with actionscript so that it's id or name value is accessible?
I included a simple example where a Button is created using mxml and in the same way it is created using actionscript. The actionscript object is inaccessible using it's "id" and "name" property.
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"
creationComplete="application1_creationCompleteHandler(event)">
<fx:Script>
<![CDATA[

asBtn.x = 200;
asBtn.id = "asButton";
asBtn.name = "asButtonName";
addElement(asBtn);
trace("mxmlButton="+this["mxmlButton"].label); // returns: mxml label

]]>
</fx:Script>
<s:Button
id="mxmlButton"
label="mxml label"
alpha="0.8"/>
</s:Application>Hi Dan,
It is a very rare occurrence when I miss not being able to access an object (object property, really) using the ["name"] notation for objects created using actionscript.
In MXML the compiler is conveniently adding an attribute to the class with the same name as the id, so you can conveniently refer to it using the [] notation. While we explicitly specify an application container to use, the MXML compiler creates a custom container which is a derivative of the base container and to that it adds properties for the children declared in MXML. I guess it also effectively calls "addElement" for us when the container is being constructed.
Your example assumes that using "addElement" to add the button to the application container is the same as declaring a variable (ie property ). It isn't, so there's no point in looking for an property of the name "as3Button" using the [] notation, because it doesn't exist. The container is managing a collection of children in it's display list and that's not the same as being accessible as properties of the container.
Generally speaking, accessing properties using the ["name"] syntax isn't necessary.
Paul
[edit: you may wonder why "addElement" doesn't conveniently also add the "id" attribute to be an property of the container class. Unfortunately, it can't because the container class would need to be dynamic and it's not. A further complication would be that adding properties at runtime would invite naming clashes at runtime with associated mayhem. MXML can do this because the compiler generates the class and can trap name duplication at compile time.
Great question, BTW.
-last edit changed my "attributes" to be "properties" in line with Adobe's terminology] -
Hi,
I'm new to both mac and LabView, so it may well be something obvious I'm missing.
I'm trying to use System Exec (http://zone.ni.com/reference/en-XX/help/371361L-01/glang/system_exec/ with LabVIEW 2014 on Mac OS X Mavericks) to call a python script to do some image processing after taking some data and saving images via LabView.
My problem is that I cannot figure out how to point it to the correct version/install of python to use, as it seems to use the pre-installed 2.7.5 apple version no matter whether that's set to be my default or not (and hence, it can't see my SciPy, PIL etc. packages that come with my Anaconda install).
It doesn't seem to matter whether I have certain packages installed for 2.7 accessable via the terminal, the LabView System Exec command line can't seem to find them either way and throws up an error if a script is called that imports them.
I've tried changing the working directory to the relevant anaconda/bin folder, I've also tried
cd /Applications/anaconda/bin; python <file.py>
as the CL input to system exec, but it's not wanting to use anything other than the apple install. I've tried Anaconda installs with both python 2.7 and 3.4, so it doesn't seem to be down to the 3.* compatibility issues alone.
Printing the python version to a string indicator box in LV via python script gives the following:
2.7.5 (default, Mar 9 2014, 22:15:05)
[GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.0.68)]
Whereas via the terminal, the default version is the anaconda install I'd like to use, currently
Python 3.4.1 |Anaconda 2.1.0 (x86_64)| (default, Sep 10 2014, 17:24:09)
[GCC 4.2.1 (Apple Inc. build 5577)] on darwin
I can do which python3.4 on the sys exec CL input to get the correct /anaconda/bin location, but if I try python3.4 <file.py>, I just get a Seg fault.
I've found examples for System Exec use and instructions for calling python scripts with specific versions, but neither works with Mac (frustratingly).
I've also tried editing the Path Environment Variable, and tried getting rid of the python 2.7 install entirely, but none of these work either (the latter just causing errors all over the shop).
So, in summary
I'd just like to know how to specify the python version LabView uses and to have use of the corresponding python libraries.
Either python version (2 or 3) will do, I'd just like to be able to use my libraries which came with Anaconda which I'll be writing my scripts with (which I installed as the correct packages are only compatible with a specific python version on Mac, which is not the specific version that Xcode was compatible with, argh).
All packages work normally when using the Anaconda version with the terminal or with Spyder.
Is there a function I can use other than System Exec? What am I missing?

Hello,
I am attempting to use python (with ctypes) to control my USB-6009. The goal is to write out an analog voltage and then read in the voltage through an analog input with ability to change the number of points averaged and the number of times this is repeated(sweeps) averaging the analog input array. The issue is that as we increase the number of times the voltage ramp is repeated (sweeps) we get a time out error (nidaq call failed with error -200284: 'Some or all of the samples requested have not yet been acquired). This has us confused because the sweeps are in a larger loop and the Daq function should be the same if there are 10 sweeps (works) or 1000 sweeps (crashes). Any insight would be greatly appreciated.

j.Hello Jamyamdy,
Honestly, I am not too sure about this, but were you able to acquire data before or is this your first trial?
From the usb-6009 product page, it says the following.
For Mac OS X and Linux users, download the NI-DAQmx Base driver software and program the USB-6009 with NI LabVIEW or C.

Is there a way of changing the alpha value of a symbol in its own timeline without ActionScript
I'm trying to make an animated banner ad where radio waves emanate from a device as they fade in and fade out.
I got it working, then realized I'd like the radio wave animation to loop repeatedly while the text in the ad comes in and out, so I thought maybe it should be a symbol and have the animation take place in its own timeline.
Problem is, when I make the symbol and double click to enter its timeline, the color effect menu disappears.
I don't feel comfortable in ActionScript yet. Is there no other way to do what I want?
Can I create the radio waves as a separate animation file, then import it into the main animation?You should be able to make seperate keyframes and then modify the alpha of any MovieClip or Graphic objects within that keyframe. After that right click somewhere between the keyframes on the timeline and select "Create Classic Tween".
NOTE: You have to have the keyframe selected on the timeline to be able to modify properties. So if you have a keyframe on frame 1, frame 10 and frame 20 set the alpha on frame 1 at 100%, frame 10 at 0% and frame 20 at 100% and it will fill in the blanks.
EDIT:
If the objects in your inner symbol are not a MovieClip or Graphic select all and then Right Click and select "Convert to Symbol" to make them one. -
Passing null/empty values from a actionscript VO to a Coldfusion ORM object
This is the situation.
If you have an actionscript VO that binds to a Coldfusion ORM object via the RemoteClass metadata and some of the values are not set, null, or empty strings and you pass it from Flex to Coldfusion then the Coldfusion deserialization barfs saying the values are not acceptable date values (for type="date") or valid emails (for validation="email") or other such validations, even if required="false" on the property.
For instance, if you have the following actionscript VO:
package vo
[RemoteClass(alias="com.companyname.Person")]
[Bindable]
public class Person
public var person_id:Number;
public var last_name:String;
public var first_name:String;
public var email:String;
public var created_date:date;
public function Person() {}
And you have the corresponding Coldfusion component:
<cfcomponent displayname="person" output="false"
alias="com.companyname.Person"
schema="dbo" persistent="true"
table="PERSON">
<cfproperty name="person_id" type="numeric" fieldtype="id" validate="integer" required="true" column="PERSON_ID"/>
<cfproperty name="last_name" type="string" column="LAST_NAME" required="true"/>
<cfproperty name="first_name" type="string" required="true" column="FIRST_NAME"/>
<cfproperty name="email" type="string" validate="email" required="false" column="EMAIL"/>
<cfproperty name="date_created" type="date" required="false" column="DATE_CREATED"/>
</cfcomponent>
Then if you pass the actionscript VO as is to Coldfusion, the deserialization complains that you do not have a valid email or a valid date for date_created. This is bad, bad, bad. Essentially if you have a validation of certain types (email being one) or a date property, or probably some other cases, then you essentially can not make it not required, it automatically makes it required because the Coldfusion serializer considers null/empty values as invalid dates or emails. But the serializer should not care for values that are not required, there has to be a way to pass null/empty values to these data types, but apparently there's not. If you pass an empty string ("") you still have the same problem. I know Coldfusion does not have null values, but there has to be a way to do this, otherwise it defeats the purpose of having required="false" and some kind of validation on the property.
There seems to be two ways around it. One is to override the implicit setters for the properties on the Coldfusion side and check for 0 length values yourself, then set the property if it is not, or create your own validation routine. I ended up creating my own validation function since I didn't want to have to write a setter function for everyone of these cases and I can pass back user friendly validation messages.
Have other people encountered this problem? How have you gotten around it? Thanks.I realize that I didn't clarify that I am using ColdFusion
for getting the data. This class was generated by the Create CFC
wizard in Flex Builder.

grabber, because it fills the category fields, i.e. colors in the EPG,
and has logos for most channels automagically available. Check the
website below for screenshots. The newest version of this script can be
found here:

USAGE
Check the web site above and/or run script with --help and start from there
HISTORY
tv_grab_nl_py used to be called tv_grab_nl_pdb, first released on
2003/07/09. The name change was necessary because more and more people
are actively contributing to this script and I always disliked using my
initials (I was just too lazy to change it). At the same time I switched
from using CVS to SVN and as a result the version numbering scheme has
changed. The lastest official release of tv_grab_nl_pdb is 0.48. The
first official release of tv_grab_nl_py is 6.
QUESTIONS
Questions (and patches) are welcome at: paul at pwdebruin dot net.
IMPORTANT NOTES
If you were using tv_grab_nl from the XMLTV bundle then enable the
compat flag or use the --compat command-line option. Otherwise, the
xmltvid's are wrong and you will not see any new data in MythTV.
CONTRIBUTORS
Main author: Paul de Bruin (paul at pwdebruin dot net)
Michel van der Laan made available his extensive collection of
high-quality logos that is used by this script.
Michael Heus has taken the effort to further enhance this script so that
it now also includes:
- Credit info: directors, actors, presenters and writers
- removal of programs that are actually just groupings/broadcasters
(e.g. "KETNET", "Wild Friday", "Z@pp")
- Star-rating for programs tipped by tvgids.nl
- Black&White, Stereo and URL info
- Better detection of Movies
- and much, much more...
Several other people have provided feedback and patches (these are the
people I could find in my email archive, if you are missing from this
list let me know):
Huub Bouma, Roy van der Kuil, Remco Rotteveel, Mark Wormgoor, Dennis van
Onselen, Hugo van der Kooij, Han Holl, Ian Mcdonald, Udo van den Heuvel.

How do I use Embed with an environment variable in an Actionscript AIR project Flash Builder 4.7
I am using Flash Builder 4.7 to build an Actionscript AIR project. The project embeds a number of png files from my local directory and I have been using absolute paths which all works fine.
I have a laptop with which I want to start developing the same project - I set up a git repository that both the laptop and main pc can pull from and so I can get the source where I need it and push it back to the central repository.
My problem is that the absolute paths for the embed commands don't work on the laptop as it has a different filesystem setup (Windows 8 with one drive as opposed to Windows 7 with a SSD and a data drive). I thought the solution would be as easy as using an environment variable to specify the path which could then point to a different physical directory on both machines, i.e:
[Embed(source = "DEVELOPER_RESOURCES/graphics/are/here.png"]
I did a bit of research and there was quite a lot mentioned about setting up resource directories using path variables which I worked through but I just can't get it to compile. The Actionscript compiler just won't find the png files however I specify the path. I tried something with a FLEX project and the compiler didn't complain but I think this is because the compiler for FLEX uses a different convention.
[Embed(source ="/Project Name/DEVELOPER_RESOURCES/graphics/are/here.png"] works with FLEX but not Actionscript.
So does anyone have a recipe for using the Embed command referencing assets using an environment variable that works across multiple machines with different file structures?I managed to find a solution on Windows which was to use symlinks and absolute paths. You an basically point one directory to another so I did something like:
mklink c:\developer_resources c:/the/local/path/to/my/resources
and then reference all resources as c:\developer_resources\...
Now as long as a developer machine has the right link (from c:\developer_resources to the place where the resources are kept) then it seems to work.
This doesn't however work for Mac and certainly isn't a solution for passing files between Mac and windows -
Creating a Popup in ActionScript vs Creating a Popup in MXML
Hello there
I think I need a little help with a couple of items. I'm using the Popup Library version 1.11 and I'm trying to open up a Popup (with an associated presentation model) which I have defined as follows.
view.popup.EditSection.mxml
view.popup.EditSectionPM.as
the view that opens the popup class (EditSection) dows the following in MXML, and it looks right, but it gives me limited access to the reference of the popup window. With MXML it looks like this http://grab.by/6Oaf
<popup:PopUpFactory id="editSectionPopup" reuse="true" modal="true">
<fx:Component>
<popupWindows:EditSection/>
</fx:Component>
<popup:behaviors>
<spark:ZoomAndFadeBehavior duration="1000"/>
<behavior:KeepCenteredBehavior/>
<behavior:CenterBehavior/>
<popup:AddPopUpToParsleyContext />
</popup:behaviors>
</popup:PopUpFactory>
instead of this, I've cobbled together the following ActionScript, but the popups look VASTLY different when they open. Here is the ActionScript.. the creationComplete runs the initializePopup() and the button click runs the openPopup().. this version looks like http://grab.by/6Oaz when opened.
It doesnt seem to honor the height, width, etc of the Class defining the popup, and when I click the different states, I get errors indicating that no such states exist... though they exist in the class
question: Why might Cairngorm be opening up the wrong (generic?) TitleWindow? What am i doing wrong here?

Alert.show("The Label"+event.toString() ,"You Clicked");Hi John,
If you're using Flex 4, the PopUpFactory isn't needed anymore, you can use the PopUpWrapper for everything. More info here: https://sourceforge.net/adobe/cairngorm/wiki/HowToUseCairngormPopup/
What's the reason you need a reference to the popup window? I ask because one very common reason is that users want to open and close it from elsewhere (i.e. a Presentation Model). For that, the popup library offers bindable property open, so all your behaviour object needs to do is to bind a Boolean to it and you don't need an extra view reference of the actual popup window. However, you could also get that if you listen to one of the open/close type events; inside each event object there's a popup property that points to the actual popup window. Regarding your AS usage, I didn't see anything wrong at first sight but maybe compare it the AS sample in the PopupTest project? But first, check if you really need to do it in AS as the MXML examples in PopupTest and on the how-to wiki read simpler IMHO.But also, let us know if it does'nt satisfy your use case.

Flex 3 vs Flex 4 Preprocessor directives and code behind (External Actionscript file)
I have a framework that I've built that I want to use on Flex3 and Flex4.
I've added pre-processor directives as per this link (http://livedocs.adobe.com/flex/3/html/help.html?content=compilers_21.html) and got my Flex 4 code to compile nicely.
I then went to flex 3 and discovered my sub-class of Application wouldn't compile because it was based off of spark. No problem, I'll add in a directive.
Except now my overridden class has duplicate code, specific to which SDK it is using.
No problem, I'll put all of the application class code in an Actionscript file and include it in both Application class declarations for each directive.
It works nicely in Flex 3, so I went to Flex 4, tried to compile and now I'm getting compiler errors saying things such as "The (private|public|protected) attribute may only be used on class property definitions." and "The (private|public|protected) attribute can only be used inside a package.
This same file works in Flex 3, but not in Flex 4.
What can I do to make the code compile in both places?
I'll work on a simple case so I can upload some code.Nevermind.
I got around this issue by renaming my sub-classed Application to "...Application".
Now I can use a directive to specify an import statement for the extends Application portion rather than specifiing the fully qualified spark.components.Application or mx.core.Application.
Lame - but done. -
Compability problem with Java and Python RSA algorithm implementation
I have client server application. Server is writtein in python, client in java. Client receives messages from server encrypted with RSA (http://stuvel.eu/rsa), and I'm unable to decrypt it. It seems that this is RSA algorithm compatibility problem. I'm using algorithm from java.security package, instatinating Cipher object like this: c = Cipher.getInstance("RSA"); . I noticed that this algorithm produces for input blocks of lengtrh <=117 ouput block of length 128. Server I guess uses the most triviall impelentation of RSA ( (1 byte is encrypted to 1 byte) So i want to make my java algorithm compatibile with this one which server uses. How to do that ? Do i have to instatinate Cipher object in different way ? Or use another library ?

First you said it was no good because it could only handle <= 117 byte inputs, now you say it is no good because it produces a 128-byte output. You're not making sense.First i said that this two RSA implementations are not compatibile, and first reason i noticed firstly is that Python imlementation for input of length N produces cryptogram of the same length. Not true. In general, the RSA encryption of any number of bytes less than the length of the modulus will produce a result of length near that of the modulus. When N is less than the length of the modulus, it is rare that N bytes of cleartext produces N bytes of ciphertext.
Java implementation for data block of length <=117 produces alwasy 128 bytes of output.Pretty much correct and very much desirable. This is primarily a function of the PKCS1 padding which is used to solve two basic problems. First, as I alluded to in my first response, it is the nature of the algorithm that leading zeros are not preserved and second when the cleartext is very small (a few bytes) the exponentiation does not roll over and it is easy to decrypt the result. Both these problems are addressed by PKCS1 padding.

After what sabre150 said i think of giving up idea of translating Python code to Java and considering to use another assymetric cryptography algorithms on both sides. Can you recommend me sth what should be compatibile with Python ?This seems to be at odds with your statement in reply #3 "Also have acces only to client code so i have to change sth in java." ! This statement is why I said "I suspect ... you have dug a deep hole".
In your position I would use the Python bindings for openssl. Once more, Google is your friend.
