This is an implementation of the AES algorithm, specifically ECB, CTR and CBC mode.
|
||||
Block size can be chosen in aes.h - available choices are AES128, AES192, AES256.
|
||||
|
||||
The implementation is verified against the test vectors in:

You should pad the end of the string with zeros if this is not the case.

For AES192/256 the key size is proportionally larger.
