Reliable implementation of PBKDF2-HMAC-SHA256 for JAVA

Question

UPDATED 2019: Bouncycastle now support PBKDF2-HMAC-SHA256 since bouncycastle 1.60

---

Is there any reliable implementation of PBKDF2-HMAC-SHA256 f

Answer 1

It is available in Java 8:

public static byte[] getEncryptedPassword(
                                         String password,
                                         byte[] salt,
                                         int iterations,
                                         int derivedKeyLength
                                         ) throws NoSuchAlgorithmException, InvalidKeySpecException {
    KeySpec spec = new PBEKeySpec(
                                 password.toCharArray(),
                                 salt,
                                 iterations,
                                 derivedKeyLength * 8
                                 );

    SecretKeyFactory f = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA256");

    return f.generateSecret(spec).getEncoded();
}
