# MIME::Base32(3pm)

Base32 encoder and decoder

## NAME

MIME::Base32 - Base32 encoder and decoder

## 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

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

The following primary functions are provided:

### decode

Synonym for `"decode_base32"`

### decode\_rfc3548

Synonym for `"decode_base32"`

### decode\_base32

```
    my $string = decode_base32($encoded_data);
```

Decode some encoded data back into a string of text or binary data.

### decode\_09AV

Synonym for `"decode_base32hex"`

### decode\_base32hex

```
    my $string_or_binary_data = MIME::Base32::decode_base32hex($encoded_data);
```

Decode some encoded data back into a string of text or binary data.

### encode

Synonym for `"encode_base32"`

### encode\_rfc3548

Synonym for `"encode_base32"`

### encode\_base32

```
    my $encoded = encode_base32("some string");
```

Encode a string of text or binary data.

### encode\_09AV

Synonym for `"encode_base32hex"`

### encode\_base32hex

```
    my $encoded = MIME::Base32::encode_base32hex("some string");
```

Encode a string of text or binary data. This uses the `"hex"` (or `"[0-9A-V]"`) method.
