[jira] Commented: (CODEC-40) [codec] Patch to add crypto-compatible BigInteger encoding support to Base64

["Henri Yandell (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CODEC-40?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12565651#action_12565651 ] 

Henri Yandell commented on CODEC-40:
------------------------------------

Also, just noticed that we'd need to get approval from Chris to use the patch. This predates moving to JIRA, so the Attachment says 'No' under the 'Apache granted permisson' bit.

> There are crypto standards that require large integers for keys to be encoded in
> base64 with some special caveats (no sign bit, padding, etc). One of the
> standards that requires this is the w3c's XML-Signature standard. This patch
> adds this support along with junit tests. This code is taken from the Apache XML
> Security project's own Base64 class and changed to be more readable and add
> junit tests.
