Package jodd.util

Class Base64

java.lang.Object

jodd.util.Base64

public class Base64
extends Object

The fastest Base64 encoder/decoder implementations. Base64 is defined in RFC 2045.

Encoding supports two modes - with or without line separator. When line separator flag is on, result will have lines with max size of 76 chars, as per spec.

When decoding, input must be valid, without illegal characters. If input contains lines, they must be 76 chars long. Lines must end with CRLF ("\r\n"), as per spec.
