Class Overview

An X.509 public key for the Digital Signature Algorithm. The difference between DSAPublicKeyImpl and DSAPublicKey is that DSAPublicKeyImpl calls writeReplace with KeyRep, and DSAPublicKey calls writeObject. See the comments in DSAKeyFactory, 4532506, and 6232513.

Public Constructors

public DSAPublicKeyImpl (BigInteger y, BigInteger p, BigInteger q, BigInteger g)

Make a DSA public key out of a public key and three parameters. The p, q, and g parameters may be null, but if so, parameters will need to be supplied from some other source before this key can be used in cryptographic operations. PKIX RFC2459bis explicitly allows DSA public keys without parameters, where the parameters are provided in the issuer's DSA public key.

Parameters

y	the actual key bits
p	DSA parameter p, may be null if all of p, q, and g are null.
q	DSA parameter q, may be null if all of p, q, and g are null.
g	DSA parameter g, may be null if all of p, q, and g are null.

Throws

InvalidKeyException

public DSAPublicKeyImpl (byte[] encoded)

Make a DSA public key from its DER encoding (X.509).

Throws

InvalidKeyException
