NAME ^

Convert::Base32 - Encoding and decoding of base32 strings

SYNOPSIS ^

  use Convert::Base32;

  $encoded = encode_base32("\x3a\x27\x0f\x93");
  $decoded = decode_base32($encoded);

DESCRIPTION ^

This module provides functions to convert string from / to Base32 encoding, specified in RACE internet-draft. The Base32 encoding is designed to encode non-ASCII characters in DNS-compatible host name parts.

See http://www.ietf.org/internet-drafts/draft-ietf-idn-race-03.txt for more details.

FUNCTIONS ^

Following functions are provided; like MIME::Base64, they are in @EXPORT array. See Exporter for details.

encode_base32($str)

Encode data by calling the encode_base32() function. This function takes a string to encode and returns the encoded base32 string.

decode_base32($str)

Decode a base32 string by calling the decode_base32() function. This function takes a string to decode and returns the decoded string.

This function might throw the exceptions such as "Data contains non-base32 characters", "Length of data invalid" and "PADDING number of bits at the end of output buffer are not all zero".
