Method Detail

engineGenerateSecret

protected javax.crypto.SecretKey engineGenerateSecret(java.security.spec.KeySpec keySpec)
                                               throws java.security.spec.InvalidKeySpecException

Generates a HMAC SecretKey object from the provided key specification (key material).

Specified by:

engineGenerateSecret in class javax.crypto.SecretKeyFactorySpi

Parameters:

keySpec - specification (key material) of the HMAC secret key

Returns:

HMAC secret key

Throws:

java.security.spec.InvalidKeySpecException - if the given key specification is inappropriate for this key factory to produce a HMAC secret key.
