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

["Christopher Schultz (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CODEC-234?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Christopher Schultz closed CODEC-234.
-------------------------------------

Tests pass, and my test client code driver (for TOTP authentication) works as expected under 1.1-SNAPSHOT but not 1.10.

Looks good to me, thanks.

> 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.
