encode_base64 - Encode string using base64 encoding
decode_base64 - Decode base64 string
SYNOPSIS
use MIME::Base64;
$encoded = encode_base64('Aladdin:open sesame');
$decoded = decode_base64($encoded);
DESCRIPTION
This module provides functions to encode and decode
strings into the Base64 encoding specified in RFC 2045 -
MIME (Multipurpose Internet Mail Extensions). The Base64
encoding is designed to represent arbitrary sequences of
octets in a form that need not be humanly readable. A
65-character subset ([A-Za-z0-9+/=]) of US-ASCII is used,
enabling 6 bits to be represented per printable character.
The following functions are provided:
encode_base64($str, [$eol])
Encode data by calling the encode_base64() function.
The first argument is the string to encode. The
second argument is the line ending sequence to use (it
is optional and defaults to "\n"). The returned
encoded string is broken into lines of no more than 76
characters each and it will end with $eol unless it is
empty. Pass an empty string as second argument if you
do not want the encoded string broken into lines.
decode_base64($str)
Decode a base64 string by calling the decode_base64()
function. This function takes a single argument which
is the string to decode and returns the decoded data.
Any character not part of the legal base64 chars is
ignored.
If you prefer not to import these routines into your
namespace you can call them as:
use MIME::Base64 ();
$encoded = MIME::Base64::encode($decoded);
$decoded = MIME::Base64::decode($encoded);
