This example describes the Base64 encryption and decryption method in Python. Share to everyone for your reference. The specific analysis is as follows: First, base64 Base64 is a representation that represents binary data based on 64 printable characters. Because 2 of the 6 times equals 64, each 6 bit is a unit, corresponding to a printable character. Three bytes have 24 bits, corresponding to 4 Base64 un

Feed Namespaces: System.Security.Cryptography.TripleDES Class Simple description: Represents the base class for triple data Encryption standard algorithms, all implementations of TripleDES must derive from this base class, but TripleDES is inherited from the SymmetricAlgorithm class. TripleDES uses the DES algorithm for three consecutive iterations. It can use two or three 56-bit keys. Purpose of Use: Secure encry
