SYNOPSIS

  use Web::Transport::Base64;
  
  $encoded = encode_web_base64 $bytes;
  $bytes = decode_web_base64 $string;

DESCRIPTION

The Web::Transport::Base64 module defines an API to encode or decode byte string using Base64.

FUNCTIONS

These functions are exported by default:

$string = encode_web_base64 $bytes

Encode a byte string using Base64 and return the result string (i.e. Base64-encoded ASCII string). The argument must not be a utf8-flagged string.

This function is an implementation of the "forgiving-base64 encode" operation of the Infra Standard.

$bytes = decode_web_base64 $string

Decode a byte or character string using Base64 and return the result byte string. If the input is not interpretable as a Base64-encoded string, undef is returned instead.

This function is an implementation of the "forgiving-base64 decode" operation of the Infra Standard.

$string = encode_web_base64url $bytes

Encode a byte string using base64url and return the result string (i.e. base64url-encoded ASCII string). The argument must not be a utf8-flagged string.

$bytes = decode_web_base64url $string

Decode a byte or character string using base64url and return the result byte string. If the input is not interpretable as a base64url-encoded string, undef is returned instead.

DEPENDENCY

This module is a wrapper of MIME::Base64, which is a core module of Perl.
