(PHP Extension) Password_Digest = Base64 (SHA-1 ( nonce + created + SHA-1 (password) ) )

Demonstrates how to compute:

Password_Digest = Base64 (SHA-1 ( nonce + created + SHA-1 (password)))

Chilkat PHP Downloads PHP Extension for Windows, Linux, MacOS, Alpine Linux, Solaris

<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

//  This example requires the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

$password = 'secret';

$crypt = new CkCrypt2();
$crypt->put_HashAlgorithm('SHA-1');
$crypt->put_EncodingMode('base64');

//  Generate a 16-byte random nonce
$prng = new CkPrng();
$bd = new CkBinData();
$prng->GenRandomBd(16,$bd);

//  Get the current date/time in a string with this format: 2010-06-08T07:26:50Z
$dt = new CkDateTime();
$dt->SetFromCurrentSystemTime();
$created = $dt->getAsTimestamp(false);
$bd->AppendString($created,'utf-8');

//  This example wishes to calculate a password digest like this:
//  Password_Digest = Base64 ( SHA-1 ( nonce + created + SHA-1(password) ) )

//  First SHA-1 digest the password...
$passwordSha1 = $crypt->hashStringENC($password);
//  Append the 20 binary bytes of the SHA1 hash to bd, which already contains the nonce and created date/time.
$bd->AppendEncoded($passwordSha1,'base64');

$passwordDigest = $crypt->hashBdENC($bd);

print 'Base64 password digest = ' . $passwordDigest . "\n";
