WebMay 30, 2024 · First, we extract the public key from the key pair and use it to encrypt some data. 32 is a random parameter used by the RSA algorithm to encrypt the data. This step simulates us publishing the encryption key and someone using it to encrypt some data before sending it to us. 1. >>> public_key = key.publickey () 2.

WebIf you're given a bit of portably-written Python code that uses the DES encryption algorithm, you should be able to use AES instead by simply changing from Crypto.Cipher import DES to from Crypto.Cipher import AES, and changing all references to DES.new() to AES.new(). It's also fairly simple to write your own modules that mimic this interface ...
