base64 encryption

Base64 encodes binary data into four-byte readable characters per three bytes. The encoded characters are about 136.1% characters in length. Character range is A-Z A-Z 0-9 \ +. However, the encoded string is not suitable for URL transmission. The

The following is a simple implementation of encrypted transmission: 1, base64.js /** * * Base64 encode / decode * * */function Base64() { // private property _keyStr = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/="; /

Today, let's look at the use of base64 cryptographic functions, and the difference between Python2 and Python3. First, base64 Base64 is a representation of binary data based on 64 printable characters. Since 2 of the 6 is equal to 64, every 6 bits
