DSAParameterSpec

AI-generated Key Takeaways

• DSAParameterSpec defines parameters for the Digital Signature Algorithm (DSA).

• It includes the prime (p), sub-prime (q), and base (g) values.

• This class implements AlgorithmParameterSpec and DSAParams interfaces.

• It provides methods to retrieve the DSA parameters: getP(), getQ(), and getG().

• A constructor allows creating a DSAParameterSpec instance with specified parameter values.
