public class BCodec extends RFC1522Codec implements StringEncoder, StringDecoder
Identical to the Base64 encoding defined by RFC 1521 and allows a character set to be specified.
RFC 1522 describes techniques to allow the encoding of non-ASCII text in various portions of a RFC 822 [2] message header, in a manner which is unlikely to confuse existing message handling software.
