Help with DES key

In my Java application, I use a DES key to encrypt files. Im not much of a security guy, so was wondering what a DES key looks like. Is it a string of characters? Is it a number?.
The reason Im asking is that my application requires the user to note down the key and remember it (perhaps by jotting it down on a piece of paper). The key value has to hence be displayed to the user. How can I display the key value in Java in a human readable form so that next time he types it into my application, the application gets the same key it printed out earlier?
Many thanks

Seems a silly approach asking the user to remember the key but you will need to encode the key from binary into human readable form. You could try Base64 or Hex encoding.
P.S. A PBE approach to the whole thing would probably be better.

I don't use ABA but BouncyCastle
this could help you :
try
java.security.Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());

Help with Unique Key Insert!!!

I need help with this <<removed by moderator>>
When i try to do an insert "A" into a DB table, the transaction fills the info on creation mode, but is not doing the same at modification mode.
Here i send the insert, i don't if the problems comes from sintaxis:
INSERT zpsprctr_det FROM TABLE it_planif ACCEPTING DUPLICATE KEYS.
tabal base datos es la zpsprctr_det
Any ideas please let me know

Hi,
with
INSERT dbtable FROM TABLE itab ACCEPTING DUPLICATE KEYS.
you will insert several lines in a database table from an internal table. Duplicate keys are ignored, the 1st entry is written.
To update them, you should use
MODIFY dbtable FROM TABLE itab.
This updates all lines that are existing or inserts all lines that are still missing. If you have duplicate keys here, the last entry will do the last update.

Help with DES decryption

Hello !
I wrote the code for DES Encryption , which i have tested and works perfectly, consistent with the results expected.
But I have not been able to implement the decryption process correctly asI have not yet understood the way i need to shift the order of keys , or their elements.I tried reversing the left shifting sequence , but it didn't solve the problem
Please suggest something .I just need to understand the exact process used for decryption.
Many Thanks..

@dstuz
I haven't been reinventing the wheel , but I have been working out the DES code on my own.
I have already coded the application for encryption & it works perfectly- thoroughly verified.
Now since i have been looking to finish the cipher by implementing the Decryption stage..i am stuck because there isn't enough info available to actually clarify my doubt.Some variation has to be made in the way we apply keys to the Right Expanded array but i haven't quite figured out how..
I can do the coding on my own..infact 90% of the coding is finished
FYI.
Its just this last step , where i have been stuck , trying to figure out how the last step is to be done.
I just need help to exactly understand the process & lend the finishing touch to the cipher.

No primary key in database table.Need help with ODS keys.

Hi ,
I am pulling data from a database table where there in no primary key . So when I designed my ODS and loaded the data , the records got overwritten...(If there are 5000 records only 4000 got transfered) . So Now the only option I can think of is putting all the database fields as key fields in my ODS but then I am restricted to only 16 fields for ODS and I have more than 24 fields in my database table.What should I do now.Any help will be appreciated.
Thanks a lot!!!

Hi,
are you trying to pull data from structures.....putting all the fields in the key fields is the ODS keys is not a solution.
what is your reporting requirement....try to maintain the keys for which you want to see the data
e.g. if in report you want to see the data for sales order then put the keys as sales order for ODS...so that the data is correct at the sales order level.
ie. the try to maintain the ODS at the level ...which can be used.
This is the just a guide....you can decide with your requirement.
Thanks

Help with understanding key event propagation

Hello,
I am hoping someone can help me understand a few things which are not clear to me with respect to handling of key events by Swing components. My understanding is summarized as:
(1) Components have 3 input maps which map keys to actions
one for when they are the focused component
one for when they are an ancestor of the focused component
one for when they are in the same window as the focused component
(2) Components have a single action map which contains actions to be fired by key events
(3) Key events go to the currently focused component
(4) Key events are consumed by the first matching action that is found
(5) Key events are sent up the containment hierarchy up to the window (in which case components with a matching mapping in the WHEN_IN_FOCUSED_WINDOW map are searched for)
(6) The first matching action handles the event which does not propagate further
I have a test class (source below) and I obtained the following console output:
Printing keyboard map for Cancel button
Level 0
Key: pressed C
Key: released SPACE
Key: pressed SPACE
Level 1
Key: pressed SPACE
Key: released SPACE
Printing keyboard map for Save button
Level 0
Key: pressed SPACE
Key: released SPACE
Level 1
Key: pressed SPACE
Key: released SPACE
Printing keyboard map for Main panel
Event: cancel // typed SPACE with Cancel button having focus
Event: save // typed SPACE with Save button having focus
Event: panel // typed 'C' with panel having focus
Event: panel // typed 'C' with Cancel button having focus
Event: panel // typed 'C' with Save button having focus
I do not understand the following aspects of its behaviour (tested on MacOSX although I believe the behaviour is not platform dependent):
(1) I assume that the actions are mapped to SPACE since the spacebar clicks the focused component but I don't explicitly set it?
(2) assuming (1) is as I described why are there two mappings, one for key pressed and one for key released yet the 'C' key action only has a key pressed set?
(3) assuming (1) and (2) are true then why don't I get the action fired twice when I typed the spacebar, once when I pressed SPACE and again when I released SPACE?
(4) I read that adding a dummy action with the value "none" (i.e. the action is the string 'none') should hide the underlying mappings for the given key, 'C' the my example so why when I focus the Cancel button and press the 'C' key do I get a console message from the underlying panel action (the last but one line in the output)?
Any help appreciated. The source is:

Use the [url http://forum.java.sun.com/help.jspa?sec=formatting]Code Formatting Tags so the posted code retains its original formatting.
1) In the Metal LAF the space bar activates the button. In the Windows LAF the Enter key is used to activate the button. Therefore these bindings are added by the LAF.
2) The pressed binding paints the button in its pressed state. The released binding paint the button in its normal state. Thats why the LAF adds two bindings.
In your case you only added a single binding.
3) The ActionEvent is only fired when the key is released. Same as a mouse click. You can hold the mouse down as long as you want and the ActionEvent isn't generated until you release the mouse. In fact, if you move the mouse off of the button before releasing the button, the ActionEvent isn't even fired at all. The mouse pressed/released my be generated by the same component.
4) Read (or reread) the [url http://java.sun.com/docs/books/tutorial/uiswing/misc/keybinding.html#howto]How to Remove Key Bindings section. "none" is only used to override the default action of a component, it does not prevent the key stroke from being passed on to its parent.

Please help with Posting Keys For Fast Entry (t.code OBXJ)

Dear experts,
Please help me to be more familiar with configurtation of Enjoy Transactions (t.code OBXJ). I want to configure fast entry transaction and change standard assignement of posting key. But there are no editing options in this transaction, just three transaction keys are predefined and posting keys are assigned to them (those are changable). But where to see what those transaction keys mean? And what could be your proposals, how to configure this IMG step?
Thanks!

Hi,
t.code OBXJ is for automatccly postings, normal you never change the standard posting keys.
In the block line items you can select colums you need and place the one's you need to the begin of the screen and in the right top corner of posting line items you can click an save this as (default) variant.
When you want to use an other posting keys you use the option complex posting (F6)

Search help with multiple key fields

Hi,
I want to dispaly search help on a field from a internal table have multiple key fields i.e combination of fld1 + fld2 +fld3 makes one single row. Therfore can any one tell me how to return that single row , because if I am using function F4IF_INT_TABLE_VALUE_REQUEST I get only one return field that I select by which I can't get the actual line that I have selected as there may be more that one line for that field.
please suggest any way through programming not by creating any search help through se11.

Need help with generating keys from xml

Hello,
I am just learning about JCE and am haveing some problems with implementing a basic program.
I have the following information:
<RSAKeyValue>
<Modulus>Base64EncodedString</Modulus>
<Exponent>Base64EncodedString</Exponent>
<P>Base64EncodedString</P>
<Q>Base64EncodedString</Q>
<DP>Base64EncodedString</DP>
<DQ>Base64EncodedString</DQ>
<InverseQ>Base64EncodedString</InverseQ>
<D>Base64EncodedString</D>
</RSAKeyValue>
From which I need to construct a public and private key. I am using RSA algorithm for the encrypting and decrypting. I am using the org.bouncycastle.jce.provider.BouncyCastleProvider provider. Any help would be greatly appreciated.
My questions are:
1) Is it possible to create the public and private key from this data?
2) How can I construct a public and private key from this data.
Thank you in advance.
Sunit.

Thanks for your help...I am still having problems.
I am now creating the public and private keys. I am generating the public exp, modulus, private exp, and the encrypted text from another source.
so my questions are:
1) How do I verfiy that the private and public keys that I generate are valid?
2) How do I get the decrypted text back in a readable form?
3) the decrypted text should read "ADAM"
Here is a test I wrote:

Help with FN keys on my new Thinkcentre Edge E73 SFF

I bought 5 brand new Lenovo Thinkcentre Edge E73 ssf desktops.
They came with wired slim usb keyboards. The problem is that i can't switch to normal F (function keys) without holding the FN key. I searched the forum and tryed several programs but nothing changes. Nothing helps.
I also looked in the bios but there's no option for the keyboard.
Please tell me what to do?
Solved!
Go to Solution.

Hello Bstruik,
I had a similar problem 1,5 years ago with an other lenovo SFF. This exe fixed it for me: http://support.lenovo.com/en_JP/downloads/detail.page?DocID=DS032471
This link points to the win8 version of the file. Not sure if it will work on win7 cause i haven't tested it myself.
I will need to test it in a couple of days as i also purchased a new E73SFF for a customer.
Lenovo, why is this exe not part of the default install? Function keys are still popular in any ERP environment...
Good luck.

Help with a key that popped off!

Hi! I was wondering if someone could help me. My dog jumped up on my lap and ripped my apple key off. How do you get these back in?? It is the apple key to the left of the space bar. Thanks!

Look at the underneath side of the key. Are all the little prongs intact and not bent out of position? If they are bent or broken, you will need to buy a new key.
You need to put the little ring back in first. (If you already have it in, you need to grab hold of the outside top and bottom and pull them up like pulling up an ironing board. Go on to the next paragraph about attaching the key.) If you don't already have the ring in, you pull it open like you would an ironing board. The front of the circle part should be down, and the outside frame on the front should come up. Take the two tabs that are now down in the back and hook them under the two metal pieces at the back of the hole on the keyboard. Take the flat front part of the circle part that is down and hook it under the metal tab on the keyboard at the front of the hole.
Next, snap the the key onto the ring part, attaching the front of the key first. Then rock it back and snap on the back part of the key. Pushing in the center of the key, push downward firmly to reseat the key.
Refer to the photos in this Knowledge Base article as you go, but, hopefully, this will help you understand the photos a little better.
Good luck!

Help with wep key

Hello,
I have a real problem and wondered if someone could help, i have a linksys wrk 54g wireless broadband router. I bought this to use with my laptop.
My laptop has broken and i do not have a pci wireless adaptor for my computer so i cannot access the router setting.... silly thing is that i have not used the router for so long i cannot connect to the wireless.
My sons nintendo ds used to use the wireless and i can see from the settings the wep was set to 10 charactors.
Is there anything you can think or do i just bin the router.
kind regards

You can try to hardwired your computer to the router, And access the router's user interface(Just leave the username balnk and the password id asmin), and go to the wireless tab thenb under wireless tab click on wireless security/. and check it for yourself what the password is for your wireless. ^_^
Many thanks,

Help with large key performance

HI ,
I have a to build 3 Z DB table and in the table one of the field is (application ID )
is in size char 255 and it's table key (and i cant change this fields) .
the tables
Table 1
mandt type mandt     " key
user   type bname    " key
application_id type char255   " key
date...
Table 2
mandt type mandt     " key
user   type bname    " key
application_id type char255   " key
application_ver type char10   " key
additional fields (not keys).
Table 3
mandt type mandt     " key
user   type bname    " key
application_id type char255   " key
application_ver type char10    " key
app_additonl    type char50     " key
additional fields (not keys).
The problem is that when i activate the table i get warning of performance
since the key is larger then 120 charcter .
the table num 3 can have more than 1000000 recoreds .
and i can have lot of read access to the table
Regards
JOy

Hi ,
Do u suggest to use the calculate Hash for char with MD5 algorithm or SH1 ,or there is other recommended scenario i that take the performance side in the picture too since the performance side is very impotent to my design .
or there is other ideas/ recommendation to my design?
Best Regards
Joy
