- This page contains one of the most extensive Web sites for encryption, and includes secret key, public key and hashing methods. It includes important public key methods such as for RSA, along with secret keys methods of 3DES, AES and RC4.
- Sep 26, 2019 This only works because the 'mysecretpassword' is 16 bytes. If it were a different (not dividable by 16) amount of bytes you'd get 'ValueError: AES key must be either 16, 24, or 32 bytes long'.
