You're welcome - I've spent quite some time on AES/Rijndael

In case you're interested, some material to read
- http://en.wikipedia.org/wiki/Advanced_Encryption_Standard
- http://encyclopedia.thefreedictionary.com/Cipher+mode
- http://encyclopedia.thefreedictionary.com/Padding+(cryptography)

Proposition ( Algo and math) http://csrc.nist.gov/archive/aes/rijndael/Rijndael-ammended.pdf
Rijndael limited to 16 byte blocksize ( = AES ) but with testvectors http://csrc.nist.gov/archive/aes/rijndael/Rijndael-ammended.pdf
