Base64 Encoder

What is Base64 Encoding?

Base64 is a binary-to-text encoding scheme that converts binary data into an ASCII string format. It's commonly used to encode data that needs to be stored or transferred over media designed to handle text. The encoding process takes every three bytes of binary data and converts them into four ASCII characters from a set of 64 printable characters.
