NAME
Crypt::Digest::MD4 - Hash function MD4 [size: 128 bits]
SYNOPSIS
### Functional interface:
use Crypt::Digest::MD4 qw( md4 md4_hex md4_b64 md4_file md4_file_hex md4_file_b64 );
# calculate digest from string/buffer
$md4_raw = md4('data string');
$md4_hex = md4_hex('data string');
$md4_b64 = md4_b64('data string');
# calculate digest from file
$md4_raw = md4_file('filename.dat');
$md4_hex = md4_file_hex('filename.dat');
$md4_b64 = md4_file_b64('filename.dat');
# calculate digest from filehandle
$md4_raw = md4_file(*FILEHANDLE);
$md4_hex = md4_file_hex(*FILEHANDLE);
$md4_b64 = md4_file_b64(*FILEHANDLE);
### OO interface:
use Crypt::Digest::MD4;
$d = Crypt::Digest::MD4->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 formDESCRIPTION
Provides an interface to the MD4 digest algorithm.
EXPORT
Nothing is exported by default.
You can export selected functions:
use Crypt::Digest::MD4 qw(md4 md4_hex md4_b64 md4_file md4_file_hex md4_file_b64);Or all of them at once:
use Crypt::Digest::MD4 ':all';FUNCTIONS
md4
Logically joins all arguments into a single string, and returns its MD4 digest encoded as a binary string.
$md4_raw = md4('data string');
#or
$md4_raw = md4('any data', 'more data', 'even more data');md4_hex
Logically joins all arguments into a single string, and returns its MD4 digest encoded as a hexadecimal string.
$md4_hex = md4_hex('data string');
#or
$md4_hex = md4_hex('any data', 'more data', 'even more data');md4_b64
Logically joins all arguments into a single string, and returns its MD4 digest encoded as a Base64 string, with trailing '=' padding.
$md4_b64 = md4_b64('data string');
#or
$md4_b64 = md4_b64('any data', 'more data', 'even more data');md4_file
Reads file (defined by filename or filehandle) content, and returns its MD4 digest encoded as a binary string.
$md4_raw = md4_file('filename.dat');
#or
$md4_raw = md4_file(*FILEHANDLE);md4_file_hex
Reads file (defined by filename or filehandle) content, and returns its MD4 digest encoded as a hexadecimal string.
$md4_hex = md4_file_hex('filename.dat');
#or
$md4_hex = md4_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.
md4_file_b64
Reads file (defined by filename or filehandle) content, and returns its MD4 digest encoded as a Base64 string, with trailing '=' padding.
$md4_b64 = md4_file_b64('filename.dat');
#or
$md4_b64 = md4_file_b64(*FILEHANDLE);METHODS
The OO interface provides the same set of functions as Crypt::Digest.
