   |For a project I'm currently developing I use latest version of JSch for J2ME
   |CDC (jsch-0.1.17-J2MECDC-20050224). In that version there is no support for
   |AES. I tried to add it by mimicing BlowfishCBC.java and TripleDESCBC.java
   |from com.jcraft.jsch.bc however it doesn't work. It ends up with
   |IndexOutOfBoundsException somewhere in Session - decryption fails probably.
   |As I am no expert in cryptography I cannot find the reason. Would anyone be
   |able to help me with this? Thank you very much.

The current implementation has expected that the size of
cipher's IV(Initial Vector) is in 8 bytes, but AES will use 16 bytes for IV.
I guess that is the reason.
I'll modify the code and post it to this list for your testing.
Please wait for a while.

Sincerely,
