javax.crypto.KeyGeneratorSpi

iaik.security.mac.HMacSha256KeyGenerator

public class HMacSha256KeyGenerator
extends VarLengthKeyGenerator

This class provides the functionality of KeyGenerator for generating keys to be used by the HmacSHA256 MAC algorithm.

An application uses

 KeyGenerator keyGen = KeyGenerator.getInstance("HmacSHA256");
 

for creating a KeyGenerator object for the HmacSHA256 algorithm. For actually generating the requested secret key from the KeyGenerator object just created, an application calls the generateKey method after optionally having initialized the generator with some random seed and/or the required key length:

 SecretKey key = keyGen.generateKey();
