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);
