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

Demonstrates how to compute:

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

<?php

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

$password = 'secret';

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Crypt2')
$crypt = new COM("Chilkat.Crypt2");
$crypt->HashAlgorithm = 'SHA-1';
$crypt->EncodingMode = 'base64';

// Generate a 16-byte random nonce
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Prng')
$prng = new COM("Chilkat.Prng");
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.BinData')
$bd = new COM("Chilkat.BinData");
$prng->GenRandomBd(16,$bd);

// Get the current date/time in a string with this format: 2010-06-08T07:26:50Z
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.CkDateTime')
$dt = new COM("Chilkat.CkDateTime");
$dt->SetFromCurrentSystemTime();
$created = $dt->getAsTimestamp(0);
$bd->AppendString($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";
