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. WebbFor more information about the format of arg see openssl-passphrase-options (1). -e. Encrypt the input data: this is the default. -d. Decrypt the input data. -a. Base64 process the data. This means that if encryption is taking place the data is base64 encoded after encryption. If decryption is set then the input data is base64 decoded before ...
