AES (Advanced Encryption Standard) is a symmetric block cipher standardizedby NIST . It has a fixed data block size of 16 bytes.Its keys can be 128, 192, or 256 bits long.
AES is very fast and secure, and it is the de facto standard for symmetricencryption.
As an example, encryption can be done as follows:
The recipient can obtain the original message using the same keyand the incoming triple (nonce,ciphertext,tag)

Python Generate Aes Key
Module’s constants for the modes of operation supported with AES:
I want to combine hashing and encryption for better security. So can I use a hash key generated from SHA-512 as a key in AES. For example, I have a password 'secret', I calculate SHA-512 hash for. Generation - python generate aes key Encrypt & Decrypt using PyCrypto AES 256 (6) Another take on this (heavily derived from solutions above) but.
