|
|
$d->add('any data');

=head1 DESCRIPTION
|
|
|
|
Provides an interface to the Keccak256 digest algorithm.
|
|
|
|
=head1 EXPORT
|
|
|
|
Nothing is exported by default.
|
|
|
|
You can export selected functions:
|
|
|
|
use Crypt::Digest::Keccak256 qw(keccak256 keccak256_hex keccak256_b64 keccak256_b64u
|
|
keccak256_file keccak256_file_hex keccak256_file_b64 keccak256_file_b64u);
|
|
|
|
Or all of them at once:
|
|
|
|
use Crypt::Digest::Keccak256 ':all';
|
|
|
|
=head1 FUNCTIONS
|
|
|
|
=head2 keccak256
|
|
|
|
Logically joins all arguments into a single string, and returns its Keccak256 digest encoded as a binary string.
|
|
|
|
$keccak256_raw = keccak256('data string');
|
|
#or
|
|
$keccak256_raw = keccak256('any data', 'more data', 'even more data');
|
|
|
|
=head2 keccak256_hex
|
|
|
|
Logically joins all arguments into a single string, and returns its Keccak256 digest encoded as a hexadecimal string.
|
|
|
|
$keccak256_hex = keccak256_hex('data string');
|
|
#or
|
|
$keccak256_hex = keccak256_hex('any data', 'more data', 'even more data');
|
|
|
|
=head2 keccak256_b64
|
|
|
|
Logically joins all arguments into a single string, and returns its Keccak256 digest encoded as a Base64 string, B<with> trailing '=' padding.
|
|
|
|
$keccak256_b64 = keccak256_b64('data string');
|
|
#or
|
|
$keccak256_b64 = keccak256_b64('any data', 'more data', 'even more data');
|
|
|
|
=head2 keccak256_b64u
|
|
|
|
Logically joins all arguments into a single string, and returns its Keccak256 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).
|
|
|
|
$keccak256_b64url = keccak256_b64u('data string');
|
|
#or
|
|
$keccak256_b64url = keccak256_b64u('any data', 'more data', 'even more data');
|
|
|
|
=head2 keccak256_file
|
|
|
|
Reads file (defined by filename or filehandle) content, and returns its Keccak256 digest encoded as a binary string.
|
|
|
|
$keccak256_raw = keccak256_file('filename.dat');
|
|
#or
|
|
$keccak256_raw = keccak256_file(*FILEHANDLE);
|
|
|
|
=head2 keccak256_file_hex
|
|
|
|
Reads file (defined by filename or filehandle) content, and returns its Keccak256 digest encoded as a hexadecimal string.
|
|
|
|
$keccak256_hex = keccak256_file_hex('filename.dat');
|
|
#or
|
|
$keccak256_hex = keccak256_file_hex(*FILEHANDLE);
|
|
|
|
B<BEWARE:> You have to make sure that the filehandle is in binary mode before you pass it as argument to the addfile() method.
|
|
|
|
=head2 keccak256_file_b64
|
|
|
|
Reads file (defined by filename or filehandle) content, and returns its Keccak256 digest encoded as a Base64 string, B<with> trailing '=' padding.
|
|
|
|
$keccak256_b64 = keccak256_file_b64('filename.dat');
|
|
#or
|
|
$keccak256_b64 = keccak256_file_b64(*FILEHANDLE);
|
|
|
|
=head2 keccak256_file_b64u
|
|
|
|
Reads file (defined by filename or filehandle) content, and returns its Keccak256 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).
|
|
|
|
$keccak256_b64url = keccak256_file_b64u('filename.dat');
