Example 96 with PBEKeySpec

use of javax.crypto.spec.PBEKeySpec in project sling by apache.

the class TopologyRequestValidator method getCiperKey.

/**
     * @param salt number of the key.
     * @return the CupherKey.
     * @throws UnsupportedEncodingException
     * @throws NoSuchAlgorithmException
     * @throws InvalidKeySpecException

    SecretKeyFactory factory = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1");
    // hashing the password 65K times takes 151ms, hashing 256 times takes 2ms.
    // Since the salt has 2^^72 values, 256 times is probably good enough.
