Base64 encoder

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is commonly used for encoding data to be transmitted over a network connection or for encoding binary files in a text-based format to be stored or sent as email attachments. The encoding process converts binary data into a text string consisting of 64 printable characters, including letters, numbers, and symbols, so the data can be safely transmitted over a network or stored in a text file without losing any information.
