NAME

       MIME::Base64::URLSafe - Perl version of Python's URL-safe base64 codec

SYNOPSIS

         use MIME::Base64::URLSafe;

         $encoded = urlsafe_b64encode('Alladdin: open sesame');
         $decoded = urlsafe_b64decode($encoded);

DESCRIPTION

       This module is a perl version of python's URL-safe base64 encoder / decoder.

       When embedding binary data in URL, it is preferable to use base64 encoding.  However, two
       characters ('+' and '/') used in the standard base64 encoding have special meanings in
       URLs, often leading to re-encoding with URL-encoding, or worse, interoperability problems.

       To overcome the problem, the module provides a variation of base64 codec compatible with
       python's urlsafe_b64encode / urlsafe_b64decode.

       Modification rules from base64:

           use '-' and '_' instead of '+' and '/'
           no line feeds
           no trailing equals (=)

       The following functions are provided:

           urlsafe_b64encode($str)
           urlsafe_b64decode($str)

       If you prefer not to import these routines to your namespace, you can call them as:

           use MIME::Base64::URLSafe ();
           $encoded = MIME::Base64::URLSafe::encode($decoded);
           $decoded = MIME::Base64::URLSafe::decode($encoded);
