$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

⚙️ 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);
