About the Base64 Encoder / Decoder

Base64 represents binary data using 64 printable ASCII characters so it can travel safely through channels that expect text, such as HTTP headers, data URLs and email bodies.

It is an encoding, not encryption: anyone can decode it. Use it for transport, never to protect secrets. This implementation is UTF-8 aware, so accented characters and emoji round-trip correctly.
