Class Base64
java.lang.Object
com.levigo.util.base.datatype.Base64
public final class Base64
- extends Object
This class provides encode/decode for RFC 2045 Base64 as defined by RFC 2045, N. Freed and N.
Borenstein. RFC 2045: Multipurpose Internet Mail Extensions (MIME) Part One: Format of Internet
Message Bodies. Reference 1996 Available at: http://www.ietf.org/rfc/rfc2045.txt This class is
used by XML Schema binary format validation
This implementation does not encode/decode streaming data. You need the data that you will
encode/decode already on a byte arrray.
