# [NAME](#NAME)

MIME::Base32 - Base32 encoder and decoder

# [SYNOPSIS](#SYNOPSIS)

```
    #!/usr/bin/env perl
    use strict;
    use warnings;
    use MIME::Base32;
    my $encoded = encode_base32('Aladdin: open sesame');
    my $decoded = decode_base32($encoded);
```

# [DESCRIPTION](#DESCRIPTION)

This module is for encoding/decoding data much the way that MIME::Base64 does.

Prior to version 1.0, MIME::Base32 used the "base32hex" (or "\[0-9A-V]") encoding and decoding methods by default. If you need to maintain that behavior, please call "encode\_base32hex" or "decode\_base32hex" functions directly.

Now, in accordance with RFC-3548, Section 5 <https://tools.ietf.org/html/rfc3548#section-5>, MIME::Base32 uses the "encode\_base32" and "decode\_base32" functions by default.

# [FUNCTIONS](#FUNCTIONS)
