Class DSAKeyPairGenerator

  • All Implemented Interfaces:
    java.security.interfaces.DSAKeyPairGenerator
    public class DSAKeyPairGenerator
extends java.security.KeyPairGenerator
implements java.security.interfaces.DSAKeyPairGenerator
    This class generates DSA key parameters and public/private key pairs according to the DSS standard NIST FIPS 186. It uses the updated version of SHA, SHA-1 as described in FIPS 180-1.

                       boolean genParams,
                       java.security.SecureRandom random)
                throws java.security.InvalidParameterException
        Initializes the DSA key pair generator. If genParams is false, a set of pre-computed parameters is used. In this case, modelen must be 512, 768, or 1024.

        Overrides:
        initialize in class java.security.KeyPairGenerator
        Parameters:
        params - the parameter set to be used to generate the keys.
        random - the source of randomness for this generator.
        Throws:

        generateKeyPair in class java.security.KeyPairGenerator
        Parameters:
        rnd - the source of random bits from which the random key generation parameters are drawn. In particular, this includes the XSEED parameter.
        Throws:
        java.security.InvalidParameterException - if the modulus is not between 512 and 1024.
