Class Base64Converter

java.lang.Object
  org.pf.util.Base64Converter

public class Base64Converter

extends java.lang.Object

A converter that allows to encode strings, byte arrays and char arrays to BASE64 and vice versa.

Currently it is based on the class Base64 from Robert Harder (http://iharder.sourceforge.net/base64). Thanks to him that he published his implementation as open source. This class mainly adds some convenience methods for string handling.
