Constructor Detail

HKDFExtractParameterSpec

public HKDFExtractParameterSpec(byte[] inKeyMaterial,
                                byte[] salt,
                                java.lang.String keyAlgorithm)

Constructs a parameter set for HKDFExtractParameterSpec from the given input key material, the salt and the Key Algorithm. The parameters are copied from the parameters to protect against subsequent modification.

Parameters:

inKeyMaterial - the inKeyMaterial.

salt - the salt.

keyAlgorithm - the name of the algorithm to use when creating SecretKey.

Throws:

java.lang.IllegalArgumentException - if input key material is null

HKDFExtractParameterSpec

public HKDFExtractParameterSpec(SecretKey inKey,
                                byte[] salt,
                                java.lang.String keyAlgorithm)

Constructs a parameter set for HKDFExtractParameterSpec from the given input key, the salt and the Key Algorithm. The parameters are copied from the parameters to protect against subsequent modification.

Parameters:

inKey - The secret input key. Cannot be null.

salt - the salt.

keyAlgorithm - the name of the algorithm to use when creating SecretKey.

Throws:

java.lang.IllegalArgumentException - if input key is null
