Examples of javax.crypto.SecretKeyFactory.generateSecret()

javax.crypto.SecretKeyFactory.generateSecret()
Generate a secret key from the specified key specification. @param keySpec the key specification. @return a secret key. @throws InvalidKeySpecException if the specified key specification cannot be used to generate a secret key.
