NAME
MIME::Base64::Perl - Encoding and decoding of base64
strings
SYNOPSIS
use MIME::Base64::Perl;
$encoded = encode_base64('Aladdin:open sesame');
$decoded = decode_base64($encoded);
DESCRIPTION
This module provide the same interface as "MIME::Base64",
but these functions are implemented in pure perl.
This module provides functions to encode and decode
strings into and from 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 USASCII is used, enabling 6 bits to be represented per
printable character.
The following functions are provided:
- encode_base64($str)
encode_base64($str, $eol); - Encode data by calling the encode_base64() function.
The first argument is the string to encode. The sec
ond argument is the line-ending sequence to use. It
is optional and defaults to "0. The returned
encoded string is broken into lines of no more than 76
characters each and it will end with $eol unless it is
empty. Pass an empty string as second argument if you
do not want the encoded string to be broken into
lines. - decode_base64($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 65-character base64 sub
set is silently ignored. Characters occurring after a
'=' padding character are never decoded.
