NAME

Crypt::Digest::SHA512_224 - Hash function SHA-512/224 [size: 224 bits]

SYNOPSIS

### Functional interface:
use Crypt::Digest::SHA512_224 qw( sha512_224 sha512_224_hex sha512_224_b64 sha512_224_b64u
                             sha512_224_file sha512_224_file_hex sha512_224_file_b64 sha512_224_file_b64u );

# calculate digest from string/buffer
$sha512_224_raw  = sha512_224('data string');
$sha512_224_hex  = sha512_224_hex('data string');
$sha512_224_b64  = sha512_224_b64('data string');
$sha512_224_b64u = sha512_224_b64u('data string');
# calculate digest from file
$sha512_224_raw  = sha512_224_file('filename.dat');
$sha512_224_hex  = sha512_224_file_hex('filename.dat');
$sha512_224_b64  = sha512_224_file_b64('filename.dat');
$sha512_224_b64u = sha512_224_file_b64u('filename.dat');
# calculate digest from filehandle
$sha512_224_raw  = sha512_224_file(*FILEHANDLE);
$sha512_224_hex  = sha512_224_file_hex(*FILEHANDLE);
$sha512_224_b64  = sha512_224_file_b64(*FILEHANDLE);
$sha512_224_b64u = sha512_224_file_b64u(*FILEHANDLE);

### OO interface:
use Crypt::Digest::SHA512_224;

$d = Crypt::Digest::SHA512_224->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 SHA512_224 digest algorithm.

EXPORT

Nothing is exported by default.

You can export selected functions:

use Crypt::Digest::SHA512_224 qw(sha512_224 sha512_224_hex sha512_224_b64 sha512_224_b64u
                                    sha512_224_file sha512_224_file_hex sha512_224_file_b64 sha512_224_file_b64u);

Or all of them at once:

use Crypt::Digest::SHA512_224 ':all';

FUNCTIONS

sha512_224

Logically joins all arguments into a single string, and returns its SHA512_224 digest encoded as a binary string.

$sha512_224_raw = sha512_224('data string');
#or
$sha512_224_raw = sha512_224('any data', 'more data', 'even more data');

sha512_224_hex

Logically joins all arguments into a single string, and returns its SHA512_224 digest encoded as a hexadecimal string.

$sha512_224_hex = sha512_224_hex('data string');
#or
$sha512_224_hex = sha512_224_hex('any data', 'more data', 'even more data');

sha512_224_b64

Logically joins all arguments into a single string, and returns its SHA512_224 digest encoded as a Base64 string, with trailing '=' padding.

$sha512_224_b64 = sha512_224_b64('data string');
#or
$sha512_224_b64 = sha512_224_b64('any data', 'more data', 'even more data');

sha512_224_b64u

Logically joins all arguments into a single string, and returns its SHA512_224 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).

$sha512_224_b64url = sha512_224_b64u('data string');
#or
$sha512_224_b64url = sha512_224_b64u('any data', 'more data', 'even more data');

sha512_224_file

Reads file (defined by filename or filehandle) content, and returns its SHA512_224 digest encoded as a binary string.

$sha512_224_raw = sha512_224_file('filename.dat');
#or
$sha512_224_raw = sha512_224_file(*FILEHANDLE);

sha512_224_file_hex

Reads file (defined by filename or filehandle) content, and returns its SHA512_224 digest encoded as a hexadecimal string.

$sha512_224_hex = sha512_224_file_hex('filename.dat');
#or
$sha512_224_hex = sha512_224_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.

sha512_224_file_b64

Reads file (defined by filename or filehandle) content, and returns its SHA512_224 digest encoded as a Base64 string, with trailing '=' padding.

$sha512_224_b64 = sha512_224_file_b64('filename.dat');
#or
$sha512_224_b64 = sha512_224_file_b64(*FILEHANDLE);

sha512_224_file_b64u

Reads file (defined by filename or filehandle) content, and returns its SHA512_224 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).

$sha512_224_b64url = sha512_224_file_b64u('filename.dat');
#or
$sha512_224_b64url = sha512_224_file_b64u(*FILEHANDLE);
