Base64Codec class

A base64 encoder and decoder.

A Base64Codec allows base64 encoding bytes into ASCII strings and decoding valid encodings back to bytes.

This implementation only handles the simplest RFC 4648 base64 and base64url encodings. It does not allow invalid characters when decoding and it requires, and generates, padding so that the input is always a multiple of four characters.
