Method Detail

engineGenerateSecret

public SecretKey engineGenerateSecret(KeySpec keySpec)
                               throws InvalidKeySpecException

Description copied from class: SecretKeyFactorySpi

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

Specified by:

engineGenerateSecret in class SecretKeyFactorySpi

Parameters:

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

Returns:

the secret key

Throws:

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

nativeGetAlgorithm

public static int nativeGetAlgorithm(byte[] algorithm)

Get the supported algorithm native ID.

Parameters:

algorithm - Null terminated string that describes the algorithm

Returns:

algorithm ID on success or -1 on error.

nativeGetCloseId

public static int nativeGetCloseId(int algorithmId)

Gets the id of the native close function.

Parameters:

algorithmId - the algorithm ID

Returns:

the id of the static native close function

Throws:

NativeException - on error
