KDFIeee1363Spec (Java Card API, Classic Edition)

All Superinterfaces:

AlgorithmParameterSpec
```
public interface KDFIeee1363Spec
extends AlgorithmParameterSpec
```
This interface specifies the set of parameters used to instantiate a DerivationFunction implementing the the KDF1 Key Derivation Function defined in the standard IEEE 1363-2000.
This interface is bound to the constant DerivationFunction.ALG_KDF_IEEE_1363.
Computation of the KDF function refers to hash(Z || P) where hash is a digest algorithm, Z is a shared secret and P key derivation parameters.

Since:
