//encrypted incoming data is of type Byte, instead of using the Decode method to convert raw data to binary, string-type data uses str.getbytes () toString str ="hello!";//here is the Encode method, which returns a byte type of encrypted data that

Base64 is one of the most common encoding methods used to transmit 8-bit code on the network. base64 encoding can be used to transmit long identification information in the HTTP environment. In other applications, binary data is often encoded in a

Base64 is a feeding bit encryption method. Why is it base64? Because no matter what plaintext is (such as Chinese characters and special symbols ), encrypted passwords are only 64 characters including letters A-Z, a-Z, 0-9, and + and, after the body
