How to Derive a key with RFC 2898 PKCS#5

Hi,
I use Sun JCE as the cryptography provider. I would like to know what are the class and method to use to derive a key defined by RFC 2898 based on PKCS#5 standard.
Thank you,
Bick

I would like to use the PBKDF2 function to derive a key from its master key, what should i put when getting the SecretKeyFactory? Should I be using "PBEWithMD5AndTripleDES"?
PBEKeySpec pbeKeySpec = new PBEKeySpec(pwd.toCharArray()), salt, count);
SecretKeyFactory skf = SecretKeyFactory.getInstance("PBEWithMD5AndTripleDES");
Key key = skf.generateSecret(pbeKeySpec);

Welcome to the forum!
No, there's no method to swap the functions of the Fn and Ctrl keys.

How to unlock ssh keys with lxde

I'm running a minimal setup with lxde. What manages ssh keys under lxde? I want to have my user's key unlocked when logged in so I can ssh and scp at will.
Thanks!

I have faced the same issue (with a WM like fluxbox/openbox, not LXDE).. There is no specific program that manages ssh keys in LXDE.
From my research, there are 3 possible solutions -
1) You can start the gnome-keyring (or is that seahorse) in LXDE (or any WM). This can manage your ssh keys
2) You can generate a new ssh key with empty passphrase.. That way, you will not be asked for passphrase everytime.. This is what I use.. Very simple to configure and use.. Note: The private key will be stored unencrypted on the disk if the passphrase is empty. It may be a security concern
3) Use "ssh-agent" and "ssh-add" command to remember the passphrase after you type it once..
You can use the snippet below:
$ eval `ssh-agent`
$ ssh-add [optional ssh private file if not ~/.ssh/id_rsa]
<enter passphrase>
More detailed configuration here - http://www.mtu.net/~engstrom/ssh-agent.php
Once you have done a ssh-add, the next time you can just start ssh-agent in the background. You can spawn an ssh-agent process when starting your X session.

How to merge source data with RFC response and post back again as Idoc

Hi All,
This is the requirement we have for an interface
The legacy application is sending Vendor master to PI 7.0
If it is new vendor then it is send as an Cremas Idoc into SAP. Legacy (New Vendor) -
> PI 7.0 -
>Cremas Idoc SAP
If it is changed Vendor legacy will only send changed fields for that Vendor.In PI we would like to call an RFC which will return all the data for that changed Vendor Number and then merge the RFC response with changed data from legacy and then send it to SAP as Cremas Idoc again with all values.
I know these can be achieved using Proxy by custom Abap Code in SAP.But we would like to avoid it.
How can we achieve it?
1.RFC lookup - Shall we use these , when PI receives changed Vendor from legacy ,it will call RFC using RFC lookup and the response message from RFC lookup should be merged with source data .Is this possible?
2.Shall we achieve this using BPM ?Is it feasible and How?
Any Help greatly appreciated
Thanks,
V

If it is changed Vendor legacy will only send changed fields for that Vendor.In PI we would like to call an RFC which will return all the data for that changed Vendor Number and then merge the RFC response with changed data from legacy and then send it to SAP as Cremas Idoc again with all values.
I am not sure why you want to pull whole data from R3 and send back to R3.
you can follow any of these approach..
if you have any indicator for new/ changed cusotmer in the legacy data then trigger CREMAS IDoc accordingly.
mapping rules will be diffrent for New and changed CREMAS idoc.
otherwise just do RFC look up for each record then based on the output(new/changed) create or update cusotmer data through CREMAS IDoc.
when changing the customer through CREMAS no need to pass whole data again. it is enough if pass the changed fields. offcourse qualifier values for segments will differ.

How to press 2 keys with "keyPress" event" at the same time?

Hi~~
I 'm now developing a Java Application that need to press 2 key(keyEvent) at the same time, but it seem not to work after trying.
So, I wonder how to make it work?
Thank~~

You can use a "modifier" (Control, Alt, Shift) key in combination with a regular key, but you can't combine regular keys unless you add some custom logic.
Basically in the keyPressed event you need to store the previous key that was pressed and add some comparison logic to see if the two keys you are monitoring where pressed back to back.

How to use tab key with JTextArea to shift focus

Hi
My problem is simple as whenevr i use tab key in my JTextArea, instaed of shifting focus to next component, it adds a tab space to my text.
How do i shift focus out of my JTextArea.

you can also redefine the textarea's TAB Key behaviour. The tutorial has a good example for that - better than i would be able to describe :-)

The network key you have entered is invalid please enter a network key with 5 or 13 characters

Hi guys im REALLY sorry im sure this has has been answered befor but i have limited access to the inet currently so im trying to get the answer ASAP.
the only post i found about this mensions the router bios upgrade but i doubt thats the issue here. this is on my computer i simply cant enter the password in it says it has to be 5 or 13 characters long and i do not know.seee how to get past this issue... it works on my computers that have "Wireless network monitoy v4.5" but i cant seem to get it working on my new vista laptop but i also had the wrong length error on my XP system when i didnt have the wireless netowrk monitor installed.
long story short my password is 128bit is 7 characters long. so what in the world do i do =( WEP by the way

You confuse the passphrase with the keys. Your passphrase may be seven characters long but your keys are not. The passphrase is used to generate the keys which you can see in the fields key 1-4. Those keys are the keys which you have to enter into your computer. The passphrase won't work often because it is not standardized how to derive the keys from the passphrase. Thus enter key 1 into the computer and make sure you have selected key 1 as transfer key if your router has the option.
The key in the router is in hexadecimals. The computer should easily recognize the format. The key is 5 or 13 bytes long. In hexadecimals each byte has two digits thus your key is either 10 or 26 hexadecimals long. With 128bit keys it is the latter.
I would recommend to use WPA or WPA2 with pre-shared key instead. WEP can be cracked within minutes. WPA is considered secured. Plus there is only the passphrase. For WPA/WPA2 the way how to derive the actual key from the passphrase is standardized. Thus there is nothing to confuse...

Primary Key With Four Column ,How to use that Column As Primary Key In Form

Dear All,
i have create composite Key as primary Key With Four Column .
How can i use these column in Form With Report Page.
How can i use these four Column as primary Key to Edit Record .
How can i do this.
Thanks
Vedant

wrap a view around your table with this bogus primary key. Use an instead of trigger to handle the inserts and updates. And then look at using surrogate keys to resolve these bad design issues...

How to change 'z' key into 'A' key with key blinding?

Although txt.setText("A") can set the text field with 'a', but it is not original input from keyboard because it cant trigger the key listener.
It is possible to perform key pressing more than a key in same time? Example, perform 'q' & 'w' keys pressing at the same time.

It is possible to perform key pressing more than a key in same time? Example, perform 'q' & 'w' keys pressing at the same time.With r.keyPress method, it only can perform single key pressed at a time. Do you have any idea how to perform multiple key pressed at a time?The javadoc for Robot.keyPress suggests ( "+The key should be released using the keyRelease method+" ) that the key remains "pressed" until you keyRelease(...) it. So, press the keys sequentially:
theRobot.keyPress(KeyEvent.VK_Q);
theRobot.keyPress(KeyEvent.VK_W);
// At this stage both Q and W are pressed "in same time"
... // do stuff
theRobot.keyRelease(KeyEvent.VK_W);
// At this stage, only Q is pressedI suspect that in real life, unless you're a very gifted musician, you don't really press keys "at the same time" (under the time resolution of a keyboard, which I imagine is around a few milliseconds).

How was created the cluster with keys in example: Sim Phone.vi

Hello all
I have LV 7.1.1
I have found the example: Sim Phone.vi
And I don't know how was created the cluster with keys?
Best regards
Iskander

It's just like any other cluster you create. Put a cluster container on the front panel and insert some Booleans. the actual Booleans are on the classic controls palette. The border of the cluster is also colored transparent with the paintbrush on the Tools palette.
