11 $encoded = encode_base32("\x3a\x27\x0f\x93");
12 $decoded = decode_base32($encoded);

15 This module provides functions to convert string from / to Base32
16 encoding, specified in RACE internet-draft. The Base32 encoding is
17 designed to encode non-ASCII characters in DNS-compatible host name
18 parts.
19
20 See http://tools.ietf.org/html/draft-ietf-idn-race-03 for more details.
21
23 Following functions are provided; like "MIME::Base64", they are in
24 @EXPORT array. See Exporter for details.
25
26 encode_base32($str)
27 Encode data by calling the encode_base32() function. This function
28 takes a string of bytes to encode and returns the encoded base32
29 string.
30
31 decode_base32($str)
32 Decode a base32 string by calling the decode_base32() function.
33 This function takes a string to decode and returns the decoded
34 string.
35
36 This function might throw the exceptions such as "Data contains
37 non-base32 characters", "Length of data invalid" and "Padding bits
38 at the end of output buffer are not all zero".
39
40 decode_base32 differs from the specification in that upper case
41 letters are treated as their lower case equivalent rather than
42 producing an error.
