Base64 is a character-encoding system that can represent binary data in ASCII text format. The Base64 algorithm is a combination of the 64-character alphabet used in telecommunications and the 64-bit integers of a computer's word size (32-bit or 64-bit).
Base64 is commonly used when data needs to be transferred over a network, often in an encrypted form. It can be used to encode binary files into human-readable text and vice versa.
