Sorry for any confusion, please let me try to clarify: the 
"Sakai" classes are still there in K1 TRUNK because we haven't 
yet ripped them out of the Sakai 2.7/trunk code and replaced them 
with the straight commons-codec ones. K1 itself uses only the 
commons-codec classes (BasicAuth.java was the last remaining K1 
code to use the "Sakai" ones).

There's an open proposal thread to kill off the remaining 
dependencies on the "Sakai" Base64 classes in Sakai 2.7/trunk 
code. If this is done, we will all be using the common-codec 
scheme.
