There is no standard command for listing all EFs and DFs on the java cards.
Most tools have a pre saved list of the file structure and select them one by one on the card. If the result is OK (9Fxx) then the specified file exists on the card.
JavacardOS will not accept order any more, please contact our partner Feitian online Store:

Re: Generate a key based on a byte array
View the below screenshot from java card API 3.0.4 DES_KEY.png DESKey contains an 8/16/24-byte key for single/2 key triple DES/3 key triple DES operations. For example: If you want to use 3 key 3DES: You will need a 24 byte array containing some data related to your password. You should use a messag...

Re: Error while in testing JavaCOS A22 dual interface Java card with RSA and encryption/signing
JFYI:
I have encountered this problem before. I found there was something wrong with RSA algo in A22CR.
Recently, I bought several A22CR cards from JavaCardOS e-shop and the cards didn't have any problem with RSA.
I guessed that the problem has been fixed.

Re: the length of cipher
That is just due to the cipher padding method. You should be able to safely ignore the last 8 bytes though as CBC mode does not cause the first block to be different even though there is additional padding.

Re: RSA encryption algorithm
For T=0 protocol, you can not receive the data in the same APDU response. You should send GET RESPONSE command to get the data.
It's the limitation of T=0 protocol.

Re: the max size of atomic transaction buffer
You'd better not do this! You may either receive 0x6F00 or have your transaction rolled back.

Re: the max size of atomic transaction buffer
It‘s set by the card manufacturer.
There are several methods in the JCSystem class that can do this - getMaxCommitCapacity and getUnusedCommitCapacity.
