NAME
Crypt::Digest::MD2 - Hash function MD2 [size: 128 bits]
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
DESCRIPTION
Provides an interface to the MD2 digest algorithm.
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';
FUNCTIONS
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');
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');
md2_b64
Logically joins all arguments into a single string, and returns its MD2 digest encoded as a Base64 string, with trailing '=' padding.
$md2_b64 = md2_b64('data string'); #or $md2_b64 = md2_b64('any data', 'more data', 'even more data');
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');
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);
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);
BEWARE: You have to make sure that the filehandle is in binary mode before you pass it as argument to the addfile() method.
md2_file_b64
Reads file (defined by filename or filehandle) content, and returns its MD2 digest encoded as a Base64 string, with trailing '=' padding.
$md2_b64 = md2_file_b64('filename.dat'); #or $md2_b64 = md2_file_b64(*FILEHANDLE);
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);
METHODS
The OO interface provides the same set of functions as Crypt::Digest.
new
$d = Crypt::Digest::MD2->new();
clone
$d->clone();
reset
$d->reset();
add
$d->add('any data'); #or $d->add('any data', 'more data', 'even more data');
addfile
$d->addfile('filename.dat'); #or $d->addfile(*FILEHANDLE);
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);
hashsize
$d->hashsize; #or Crypt::Digest::MD2->hashsize(); #or Crypt::Digest::MD2::hashsize();
digest
$result_raw = $d->digest();
hexdigest
$result_hex = $d->hexdigest();
b64digest
$result_b64 = $d->b64digest();
b64udigest
$result_b64url = $d->b64udigest();
