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:

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 key size is proportionally larger.
