public class Base64Encoder

extends java.lang.Object

Converts data to a base64 transformed string.

Usually one of the methods encode() must be used. However if you plan to pack some data to a value of a HTTP CGI parameter, one of the methods encodeForCGI() should be used. encodeForCGI() does the same job like encode(), but after the base64 transformation has been done, some result chars of the base64 string will be replaced:

• '=' will be replaced by '@'
• '+' will be replaced by '$'
• '/' will be replaced by '.'

This additional functionality of encodeForCGI() guarantees, that the converted value will not affect other CGI parameters.
