DESCRIPTIONThis 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://tools.ietf.org/html/draft-ietf-idn-race-03 for more details.
FUNCTIONSFollowing functions are provided; like "MIME::Base64", they are in @EXPORT array. See Exporter for details.
- Encode data by calling the encode_base32() function. This function takes a string of bytes to encode and returns the encoded base32 string.
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 bits at the end of output buffer are not all zero''.
decode_base32 differs from the specification in that upper case letters are treated as their lower case equivalent rather than producing an error.
