MIME::Base64::URLSafe(3pm) User Contributed Perl Documentation MIME::Base64::URLSafe(3pm) 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); SEE ALSO
