I'm doing a little MIDLet, where I need to encrypt some texts. I'm using SATSA API for that encryption purposes. Cipher class to actual enryption


Here is what I have blocksize, what algorithm is used and what kind of padding is used.

Here is how I do actual crypting

One thing here is unclear to me. I noticed, that if remainder is 0 (zero), I have to increase ciphertextLength one blocksize. So actual byte table is then plaintext + blocksize. Otherwise, if table cipherText is as big as plaintext, ShortBufferException is thrown.

Can somebody explain why I have to do this. I assume, that something added to that cipherText table more, than just plaintext. But what is that.

Thanks for your answers!
