DESCRIPTION

Provides an interface to the Keccak384 digest algorithm.

EXPORT

Nothing is exported by default.

You can export selected functions:

use Crypt::Digest::Keccak384 qw(keccak384 keccak384_hex keccak384_b64 keccak384_b64u
keccak384_file keccak384_file_hex keccak384_file_b64 keccak384_file_b64u);

Or all of them at once:

use Crypt::Digest::Keccak384 ':all';

FUNCTIONS

keccak384

Logically joins all arguments into a single string, and returns its Keccak384 digest encoded as a binary string.

$keccak384_raw = keccak384('data string');
#or
$keccak384_raw = keccak384('any data', 'more data', 'even more data');

keccak384_hex

Logically joins all arguments into a single string, and returns its Keccak384 digest encoded as a hexadecimal string.

$keccak384_hex = keccak384_hex('data string');
#or
$keccak384_hex = keccak384_hex('any data', 'more data', 'even more data');

keccak384_b64

Logically joins all arguments into a single string, and returns its Keccak384 digest encoded as a Base64 string, with trailing ’=’ padding.

$keccak384_b64 = keccak384_b64('data string');
#or
$keccak384_b64 = keccak384_b64('any data', 'more data', 'even more data');

keccak384_b64u

Logically joins all arguments into a single string, and returns its Keccak384 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).

$keccak384_b64url = keccak384_b64u('data string');
#or
$keccak384_b64url = keccak384_b64u('any data', 'more data', 'even more data');

keccak384_file

Reads file (defined by filename or filehandle) content, and returns its Keccak384 digest encoded as a binary string.

$keccak384_raw = keccak384_file('filename.dat');
#or
$keccak384_raw = keccak384_file(*FILEHANDLE);

keccak384_file_hex

Reads file (defined by filename or filehandle) content, and returns its Keccak384 digest encoded as a hexadecimal string.

$keccak384_hex = keccak384_file_hex('filename.dat');
#or
$keccak384_hex = keccak384_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.

keccak384_file_b64

Reads file (defined by filename or filehandle) content, and returns its Keccak384 digest encoded as a Base64 string, with trailing ’=’ padding.

$keccak384_b64 = keccak384_file_b64('filename.dat');
#or
$keccak384_b64 = keccak384_file_b64(*FILEHANDLE);

keccak384_file_b64u

Reads file (defined by filename or filehandle) content, and returns its Keccak384 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).

$keccak384_b64url = keccak384_file_b64u('filename.dat');
#or
$keccak384_b64url = keccak384_file_b64u(*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;
