#  A hash algorithm needs to be set for PBES1:
$crypt->put_HashAlgorithm("md5");

#  Indicate that the encrypted bytes should be returned
#  as a hex string:
$crypt->put_EncodingMode("hex");

#  The output should be: E729548140D20B14E9140F832A7E980AA449A84B295C75CE
print $encryptedText . "\r\n";

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

print $decryptedText . "\r\n";

The code above duplicates this Java JCE example:

	public static void main(String args[]) throws Exception
	{
	    PBEKeySpec pbeKeySpec;
	    PBEParameterSpec pbeParamSpec;
	    SecretKeyFactory keyFac;

	    // Salt
	    byte[] salt = {
		(byte)0xc7, (byte)0x73, (byte)0x21, (byte)0x8c,
		(byte)0x7e, (byte)0xc8, (byte)0xee, (byte)0x99
	    };

	    // Iteration count
	    int count = 20;

	    // Create PBE parameter set
	    pbeParamSpec = new PBEParameterSpec(salt, count);

	    String password = "secret";
	    pbeKeySpec = new PBEKeySpec(password.toCharArray());
	    keyFac = SecretKeyFactory.getInstance("PBEWithMD5AndDES");
	    SecretKey pbeKey = keyFac.generateSecret(pbeKeySpec);

	    // Create PBE Cipher
	    Cipher pbeCipher = Cipher.getInstance("PBEWithMD5AndDES");

	    // Initialize PBE Cipher with key and parameters
	    pbeCipher.init(Cipher.ENCRYPT_MODE, pbeKey, pbeParamSpec);

	    // Our cleartext
	    byte[] cleartext = "This is another example".getBytes();
	    
	    // Encrypt the cleartext
	    byte[] ciphertext = pbeCipher.doFinal(cleartext);
	    
     	System.out.print("ciphertext: ");
        System.out.println(toHex(ciphertext));
	}
