I'm trying to achieve AES/CFB/NoPadding using BouncyCastle in J2ME.
I need that only because several other components in my system already are using that algorithm and J2ME optional package(JSR 177) supports AES but not CFB flavor.Iam getting a NoSuchAlogrithmException
So iam using bouncycastle and
I got an instance of cipher in the following way.

The above code works fine but if i give "abcdefghijklmo" as the input a DataLengthException is being thrown. But i need the capability to encrypt a 15 letter string also.
The crypto.Cipher in j2Se works fine with 15 letter strings also.
And more over if i have a 20 letter string.The encryptBlock function in CFBBlockCipher is giving only encrypted first 16 letters.
I'm sorry if my question is naive but i tried a lot and bouncycastle is poorly documented. I can't help.

Thanks in advance.
