converters/p5-MIME-Base64-URLSafe 0.01nb19 NetBSD

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 (=)
