What is Base64
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. The encoding is done by mapping each set of 6 bits in the input data to a unique 64-character alphabet. The most common Base64 alphabet consists of 64 characters, including the 26 uppercase and lowercase letters of the English alphabet, the 10 decimal digits, plus "+" and "/". Base64 encoding is commonly used for encoding binary data in data URLs, for encoding user credentials for HTTP Basic Authentication, and for encoding binary attachments in email messages.
