Subject [jira] [Commented] (CODEC-140) isBase64 returns true for any UTF8 string
Date Wed, 08 May 2013 11:35:16 GMT

    [ https://issues.apache.org/jira/browse/CODEC-140?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13651805#comment-13651805

Sebb commented on CODEC-140:
----------------------------

Adding further validation to check the length etc would change the behaviour of the method,
which is currently clearly documented to only check for valid characters in the Base64 alphabet.

Not sure it's worth creating 3 other methods to add this extra validation.

> I just called Base64.isBase64("Hello") for instance and it returns true. I thought it
would return true only if it is valid base64 encoded string.
