Class LunaKeyPairGeneratorDsa

java.lang.Object

java.security.KeyPairGeneratorSpi

com.safenetinc.luna.provider.keygen.LunaKeyPairGeneratorDsa

public class LunaKeyPairGeneratorDsa
extends java.security.KeyPairGeneratorSpi

Engine class for generating DSA key pairs. The Luna provider will only generate DSA keys that have parameters compliant with FIPS 186-3. The prime and subprime must be one of:

• 1024-160
• 2048-224
• 2048-256
• 3072-256

If only a keysize is given, a set of pre-computed parameters is used (a keysize of 2048 will use a sub-prime of length 256). If no initialization is done, the generator will use the pre-computed 2048-256 parameters.

Method Detail

initialize

public void initialize(java.security.spec.AlgorithmParameterSpec params,
              java.security.SecureRandom random)
                throws java.security.InvalidAlgorithmParameterException

Initializes the key pair generator using the specified parameter set. The Luna HSM supplies its own source of randomness so the random parameter is ignored.

Overrides:

initialize in class java.security.KeyPairGeneratorSpi

Parameters:

random - unused

Throws:

java.security.InvalidAlgorithmParameterException

initialize

public void initialize(int keysize,
              java.security.SecureRandom random)
                throws java.security.InvalidParameterException

Specified by:

initialize in class java.security.KeyPairGeneratorSpi

Throws:

java.security.InvalidParameterException

generateKeyPair

public java.security.KeyPair generateKeyPair()

Specified by:

generateKeyPair in class java.security.KeyPairGeneratorSpi
