base64

This project demonstrates how Base64 works in C, which does not natively support it, so we have to resort to using an external library.

C library and command line tool for encoding/decoding base16, base32, base32hex, base64 or base64url data stream per RFC 4648, MIME base64 Content-Transfer-Encoding per RFC 2045, or PEM Printable Encoding per RFC 1421.
