Cipher / 3DES / CFB / Java and PHP

Question

I have a PHP servor which decrypt data in 3DES with the CFB Mode

I encrypt in PHP :

$montant = "500";
$message_crypte = mcrypt_encrypt(MCRYPT_3DES, "N4y1FRDRJ7wn7eJNnWaahCIS", $montant, ,CRYPT_MODE_CFB, "NCNPJDcR");
$montant = base64_encode($message_crypte);

This script in PHP is OK with other system.

And I want to encrypt in Java :

public class CryptData {
    private KeySpec keySpec;
    private SecretKey key;
    private IvParameterSpec iv;

    public CryptData(String keyString, String ivString) {
        try {
            final MessageDigest md = MessageDigest.getInstance("md5");

            final byte[] digestOfPassword = md.digest(Base64
                    .decodeBase64(keyString.getBytes("ISO-8859-1")));

            final byte[] keyBytes = Arrays.copyOf(digestOfPassword, 24);
            for (int j = 0, k = 16; j < 8;) {
                keyBytes[k++] = keyBytes[j++];
            }

            //keySpec = new DESedeKeySpec(keyBytes);
            keySpec = new DESedeKeySpec(keyString.getBytes());

            key = SecretKeyFactory.getInstance("DESede")
                    .generateSecret(keySpec);

            iv = new IvParameterSpec(ivString.getBytes());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    public String encrypt(String value) {
        try {
            Cipher ecipher = Cipher.getInstance("DESede/CFB/NoPadding");

                    //"SunJCE");
            ecipher.init(Cipher.ENCRYPT_MODE, key, iv);

            if (value == null)
                return null;

            // Encode the string into bytes using utf-8
            byte[] valeur = value.getBytes("ISO-8859-1");
            //byte[] utf8 = value.getBytes();

            // Encrypt
            byte[] enc = ecipher.doFinal(valeur);

            // Encode bytes to base64 to get a string
            return new String(Base64.encodeBase64(enc), "ISO-8859-1");
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }
}

I have not the same result in PHP and in Java

How modify Java treatment to obtain the same result as PHP?

Answer 1

The answer is:

Cipher ecipher = Cipher.getInstance("DESede/CFB8/NoPadding");

I need to use "CFB8"
