javax.crypto.KeyGeneratorSpi

iaik.security.mac.HMacShaKeyGenerator

public class HMacShaKeyGenerator
extends VarLengthKeyGenerator

This class provides the functionality of KeyGenerator for generating keys to be used by the HmacSHA1 MAC algorithm.

An application uses

 KeyGenerator keyGen = KeyGenerator.getInstance("HmacSHA1");
 

for creating a KeyGenerator object for the HmacSHA1 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();
