For those following along, I have created a new Jira issue to    
track the conversion from the "Sakai" CommonsCodecBase64 methods 
to the Apache commons-code Base64 methods:

http://jira.sakaiproject.org/browse/KNL-270

It has 3 sub-tasks:

http://jira.sakaiproject.org/browse/KNL-257
http://jira.sakaiproject.org/browse/KNL-271
http://jira.sakaiproject.org/browse/KNL-222
