(PHP ActiveX) PBES1 Password-Based Encryption (PBE)

Demonstrates how to implement password-based encryption according to the PKCS #5 v2.0: Password-Based Cryptography Standard (published by RSA Laboratories). This example uses PBES1, which ise based on the PBKDF1 function and an underlying block cipher such as RC2, DES, etc.

<?php

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

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Crypt2')
$crypt = new COM("Chilkat.Crypt2");

// Set properties for PBES1 encryption:

$crypt->CryptAlgorithm = 'pbes1';
$crypt->PbesPassword = 'mySecretPassword';

// Set the underlying PBE algorithm (and key length):
// For PBES1, the underlying algorithm must be either
// 56-bit DES or 64-bit RC2 
// (this is according to the PKCS#5 specifications at
// http://www.rsa.com/rsalabs/node.asp?id=2127   )
$crypt->PbesAlgorithm = 'rc2';
$crypt->KeyLength = 64;

// The salt for PBKDF1 is always 8 bytes:
$crypt->SetEncodedSalt('0102030405060708','hex');

// A higher iteration count makes the algorithm more
// computationally expensive and therefore exhaustive
// searches (for breaking the encryption) is more difficult:
$crypt->IterationCount = 1024;

// A hash algorithm needs to be set for PBES1:
$crypt->HashAlgorithm = 'sha1';

// Indicate that the encrypted bytes should be returned
// as a hex string:
$crypt->EncodingMode = 'hex';

$plainText = 'To be encrypted.';

$encryptedText = $crypt->encryptStringENC($plainText);

print $encryptedText . "\n";

// Now decrypt:
$decryptedText = $crypt->decryptStringENC($encryptedText);

print $decryptedText . "\n";

?>
