WebbThe mbx_sm4_encrypt/decrypt_cfb128_mb16() function returns the status that indicates whether the operation completed successfully or not. The status value of 0 indicates … 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.
