Spring versions that I am using are,
Spring : 2.5.6
Spring Security : 2.0.4
and the page into given link states , since 3.0
/**

Another thing is, that implementation has Maximum line length (76) of Base64 output. Does it truncate of the output if large than 76 characters? or what characters it appends after 76the characters.
