# CGI::Application::Plugin::Authentication::Driver::Filter::md5(3pm)

MD5 filter

## NAME

CGI::Application::Plugin::Authentication::Driver::Filter::md5 - MD5 filter

## METHODS

### filter ( (hex base64 binary), $string )

This will generate an MD5 hash of the string in the requested format.  By default, hex encoding is used.

```
 my $filtered = $class->filter('base64', 'foobar'); # OFj2IjCsPJFfMAxmQxLGPw
 -or-
 my $filtered = $class->filter(undef, 'foobar'); # 3858f62230ac3c915f300c664312c63f
```

### check ( (hex base64 binary), $string, $md5 )

This will generate an MD5 hash of the string, and compare it against the provided MD5 string. If no encoding type is specified, the length of the MD5 string will be tested to see what format it is in.

```
 if ($class->check(undef, 'foobar', '3858f62230ac3c915f300c664312c63f')) {
     # they match
 }
```
