Fix truncation rules for base64 encoding Commit e1d917182 added support for base64url encoding, a base64 variant intended to be safe for usage in URLs and filenames. The padding rules for base64url and base64 differ in that base64url require no extra '=' padding, but the commit unintentionally relaxed this requirement for base64 as well. Fix by making sure that the truncation logic check for the encoding and add a test to make sure.
