DSAPublicKeySpec

AI-generated Key Takeaways

• DSAPublicKeySpec specifies a DSA public key and its parameters (prime, sub-prime, base).

• It provides methods to retrieve the public key (y) and associated parameters (p, q, g).

• This class implements KeySpec and is used with KeyFactory to generate DSA public keys.

• A constructor is available to create a DSAPublicKeySpec instance with the necessary values.
