WebbThe SM4 algorithm requires the message to be of any length that is a multiple of 16. By default, the length of the message to encrypt / decrypt is assured by users. You may choose to turn on PKCS5 Padding Mode(by passing the argument padding with a TRUTHY value), telling Python to do the padding before encryption for you. WebbCAST5 (also known as CAST-128) is a block cipher approved for use in the Canadian government by the Communications Security Establishment. It is a variable key length cipher and supports keys from 40-128 bits in length. key ( bytes-like) – The secret key, This must be kept secret. 40 to 128 bits in length in increments of 8 bits.
