public final class Base64

extends java.lang.Object

This class is intended to replace the original one (version 1.3) to make use of the ByteCream Base64 Encoder. To use it, add the jar to your classpath before tomcat*.jar. All the comments and the decoding code are from the original class written by the ASF.
