After implementing DES, the next obvious challenge was AES. I was expecting AES code to be simpler to write than DES’ because AES was designed to be implemented in hardware or software, while DES design was geared towards hardware. This time, however, I decided to write an object-oriented API supporting the three different key sizes AES inherited from Rijndael (128-, 192- and 256-bit). In addition, besides the ECB (Electronic Code Book) basic operation mode, this implementation also supports CBC (Cipher Block Chaining) mode.

The code below informally verify the correctness of the implementation with the help of the test vectors described in NIST document SP800-38A, Recommendation for Block Cipher Modes of Operation – Methods and Techniques:

Run import pyaes, pbkdf2, binascii, os, secrets # Derive a 256-bit AES encryption key from the password password = 's3cr3t.c0d3' passwordSalt = os.urandom (16) key = pbkdf2.PBKDF2 (password, passwordSalt).read (32) print ('AES encryption key:', binascii.hexlify (key)). Generate a random 128-bit key (k1), a random 128-bit IV, and a random salt (64 bits is probably sufficient). Use PBKDF2 to generate a 256-bit key from your password and the salt, then split that into two 128-bit keys (k2, k3). Make sure your algorithm's native output is. Python Generate An Aes.
