[jira] [Created] (CODEC-234) Base32.decode should support lowercase letters

Christopher Schultz created CODEC-234:
-----------------------------------------

             Summary: Base32.decode should support lowercase letters
                 Key: CODEC-234
                 URL: https://issues.apache.org/jira/browse/CODEC-234
             Project: Commons Codec
          Issue Type: Improvement
    Affects Versions: 1.10
            Reporter: Christopher Schultz
            Priority: Minor


Base32.decode accepts a String input, but any lowercase characters are ignored -- e.g. Base32.decode("abcd2345") will give a different result than Base32.decode("ABCD1234") with no errors and a surprise to a developer.

Accepting any case is desirable, as RFC 4648 makes it clear that case-insensitivity is a goal for Base32 encoding.
