Class LunaAlgorithmParameterGeneratorDSA

java.lang.Object

java.security.AlgorithmParameterGeneratorSpi

com.safenetinc.luna.provider.param.LunaAlgorithmParameterGeneratorDSA

public class LunaAlgorithmParameterGeneratorDSA
extends java.security.AlgorithmParameterGeneratorSpi

Engine class for generating DSA key parameters. The following key sizes and corresponding sub-prime sizes are supported:

• 1024 bit key, 160 bit sub-prime (default)
• 2048 bit key, 224 bit sub-prime
• 3072 bit key, 256 bit sub-prime

Generating parameters for larger keys can be time-consuming. Although the average time taken is generally much less, key generation could take a few minutes for 2048 bit keys, and up to half an hour for 3072 bit keys.
