=head1 NAME
Crypt::Digest::MD2 - Hash function MD2 [size: 128 bits]
=head1 SYNOPSIS
### Functional interface:
use Crypt::Digest::MD2 qw( md2 md2_hex md2_b64 md2_b64u
md2_file md2_file_hex md2_file_b64 md2_file_b64u );
# calculate digest from string/buffer
$md2_raw = md2('data string');
$md2_hex = md2_hex('data string');
$md2_b64 = md2_b64('data string');
$md2_b64u = md2_b64u('data string');
# calculate digest from file
$md2_raw = md2_file('filename.dat');
$md2_hex = md2_file_hex('filename.dat');
$md2_b64 = md2_file_b64('filename.dat');
$md2_b64u = md2_file_b64u('filename.dat');
# calculate digest from filehandle
$md2_raw = md2_file(*FILEHANDLE);
$md2_hex = md2_file_hex(*FILEHANDLE);
$md2_b64 = md2_file_b64(*FILEHANDLE);
$md2_b64u = md2_file_b64u(*FILEHANDLE);
### OO interface:
use Crypt::Digest::MD2;
$d = Crypt::Digest::MD2->new;
$d->add('any data');
$d->addfile('filename.dat');
$d->addfile(*FILEHANDLE);
$result_raw = $d->digest; # raw bytes
$result_hex = $d->hexdigest; # hexadecimal form
$result_b64 = $d->b64digest; # Base64 form
$result_b64u = $d->b64udigest; # Base64 URL Safe form
=head1 DESCRIPTION
Provides an interface to the MD2 digest algorithm.
=head1 EXPORT
Nothing is exported by default.
You can export selected functions:
use Crypt::Digest::MD2 qw(md2 md2_hex md2_b64 md2_b64u
md2_file md2_file_hex md2_file_b64 md2_file_b64u);
Or all of them at once:
use Crypt::Digest::MD2 ':all';
=head1 FUNCTIONS
=head2 md2
Logically joins all arguments into a single string, and returns its MD2 digest encoded as a binary string.
$md2_raw = md2('data string');
#or
$md2_raw = md2('any data', 'more data', 'even more data');
=head2 md2_hex
Logically joins all arguments into a single string, and returns its MD2 digest encoded as a hexadecimal string.
$md2_hex = md2_hex('data string');
#or
$md2_hex = md2_hex('any data', 'more data', 'even more data');
=head2 md2_b64
Logically joins all arguments into a single string, and returns its MD2 digest encoded as a Base64 string, B<with> trailing '=' padding.
$md2_b64 = md2_b64('data string');
#or
$md2_b64 = md2_b64('any data', 'more data', 'even more data');
=head2 md2_b64u
Logically joins all arguments into a single string, and returns its MD2 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).
$md2_b64url = md2_b64u('data string');
#or
$md2_b64url = md2_b64u('any data', 'more data', 'even more data');
=head2 md2_file
Reads file (defined by filename or filehandle) content, and returns its MD2 digest encoded as a binary string.
$md2_raw = md2_file('filename.dat');
#or
$md2_raw = md2_file(*FILEHANDLE);
=head2 md2_file_hex
Reads file (defined by filename or filehandle) content, and returns its MD2 digest encoded as a hexadecimal string.
$md2_hex = md2_file_hex('filename.dat');
#or
$md2_hex = md2_file_hex(*FILEHANDLE);
B<BEWARE:> You have to make sure that the filehandle is in binary mode before you pass it as argument to the addfile() method.
=head2 md2_file_b64
Reads file (defined by filename or filehandle) content, and returns its MD2 digest encoded as a Base64 string, B<with> trailing '=' padding.
$md2_b64 = md2_file_b64('filename.dat');
#or
$md2_b64 = md2_file_b64(*FILEHANDLE);
=head2 md2_file_b64u
Reads file (defined by filename or filehandle) content, and returns its MD2 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).
$md2_b64url = md2_file_b64u('filename.dat');
#or
$md2_b64url = md2_file_b64u(*FILEHANDLE);
=head1 METHODS

$d = Crypt::Digest::MD2->new();
=head2 clone
$d->clone();
=head2 reset
$d->reset();

=head2 addfile
$d->addfile('filename.dat');
#or
$d->addfile(*FILEHANDLE);
=head2 add_bits
$d->add_bits($bit_string); # e.g. $d->add_bits("111100001010");
#or
$d->add_bits($data, $nbits); # e.g. $d->add_bits("\xF0\xA0", 16);
=head2 hashsize
$d->hashsize;
#or
Crypt::Digest::MD2->hashsize();
#or
Crypt::Digest::MD2::hashsize();
