This is an implementation of the AES algorithm, specifically ECB 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:

NOTE: String length must be evenly divisible by 16byte (str_len % 16 == 0)
|
||||
You should pad the end of the string with zeros if this is not the case.
|
||||
For AES192/256 the block size is proportionally larger.
