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 (=)
