Handling of embedded padding in base64 encoded data changed in 1.4
------------------------------------------------------------------
Key: CODEC-91
URL: https://issues.apache.org/jira/browse/CODEC-91
Project: Commons Codec
Issue Type: Bug
Affects Versions: 1.4
Reporter: Chris Pimlott
1.4 changed the way that embedded padding characters (i.e. "=") were handled
when decoding base64 data. Previously, the decoder ignored them and decoded
all the data. Now it stops upon encountering the first padding byte. This
breaks compatibility with previous versions.
For example, in 1.4,
b64.decode("Y29tbW9ucwo=".getBytes());
gives the same result as
b64.decode("Y29tbW9ucwo=Y29tbW9ucwo=".getBytes());
