NAME
Crypt::Digest::Keccak512 - Hash function Keccak-512 [size: 512 bits]
SYNOPSIS
### Functional interface:
use Crypt::Digest::Keccak512 qw( keccak512 keccak512_hex keccak512_b64 keccak512_b64u
keccak512_file keccak512_file_hex keccak512_file_b64 keccak512_file_b64u );
# calculate digest from string/buffer
$keccak512_raw = keccak512('data string');
$keccak512_hex = keccak512_hex('data string');
$keccak512_b64 = keccak512_b64('data string');
$keccak512_b64u = keccak512_b64u('data string');
# calculate digest from file
$keccak512_raw = keccak512_file('filename.dat');
$keccak512_hex = keccak512_file_hex('filename.dat');
$keccak512_b64 = keccak512_file_b64('filename.dat');
$keccak512_b64u = keccak512_file_b64u('filename.dat');
# calculate digest from filehandle
$keccak512_raw = keccak512_file(*FILEHANDLE);
$keccak512_hex = keccak512_file_hex(*FILEHANDLE);
$keccak512_b64 = keccak512_file_b64(*FILEHANDLE);
$keccak512_b64u = keccak512_file_b64u(*FILEHANDLE);
### OO interface:
use Crypt::Digest::Keccak512;
$d = Crypt::Digest::Keccak512->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 Keccak512 digest algorithm.
EXPORT
Nothing is exported by default.
You can export selected functions:
use Crypt::Digest::Keccak512 qw(keccak512 keccak512_hex keccak512_b64 keccak512_b64u
keccak512_file keccak512_file_hex keccak512_file_b64 keccak512_file_b64u);
Or all of them at once:
use Crypt::Digest::Keccak512 ':all';
FUNCTIONS
keccak512
Logically joins all arguments into a single string, and returns its Keccak512 digest
encoded as a binary string.
$keccak512_raw = keccak512('data string');
#or
$keccak512_raw = keccak512('any data', 'more data', 'even more data');
keccak512_hex
Logically joins all arguments into a single string, and returns its Keccak512 digest
encoded as a hexadecimal string.
$keccak512_hex = keccak512_hex('data string');
#or
$keccak512_hex = keccak512_hex('any data', 'more data', 'even more data');
keccak512_b64
Logically joins all arguments into a single string, and returns its Keccak512 digest
encoded as a Base64 string, with trailing '=' padding.
$keccak512_b64 = keccak512_b64('data string');
#or
$keccak512_b64 = keccak512_b64('any data', 'more data', 'even more data');
keccak512_b64u
Logically joins all arguments into a single string, and returns its Keccak512 digest
encoded as a Base64 URL Safe string (see RFC 4648 section 5).
$keccak512_b64url = keccak512_b64u('data string');
#or
$keccak512_b64url = keccak512_b64u('any data', 'more data', 'even more data');
keccak512_file
Reads file (defined by filename or filehandle) content, and returns its Keccak512 digest
encoded as a binary string.
$keccak512_raw = keccak512_file('filename.dat');
#or
$keccak512_raw = keccak512_file(*FILEHANDLE);
keccak512_file_hex
Reads file (defined by filename or filehandle) content, and returns its Keccak512 digest
encoded as a hexadecimal string.
$keccak512_hex = keccak512_file_hex('filename.dat');
#or
$keccak512_hex = keccak512_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.
keccak512_file_b64
Reads file (defined by filename or filehandle) content, and returns its Keccak512 digest
encoded as a Base64 string, with trailing '=' padding.
$keccak512_b64 = keccak512_file_b64('filename.dat');
#or
$keccak512_b64 = keccak512_file_b64(*FILEHANDLE);
keccak512_file_b64u
Reads file (defined by filename or filehandle) content, and returns its Keccak512 digest
encoded as a Base64 URL Safe string (see RFC 4648 section 5).
$keccak512_b64url = keccak512_file_b64u('filename.dat');
#or
$keccak512_b64url = keccak512_file_b64u(*FILEHANDLE);
