| public DSAPublicKey(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.

| protected void parseKeyBits() throws InvalidKeyException Overrides sun. Doc from sun. Parse the key bits. This may be redefined by subclasses to take
advantage of structure within the key. For example, RSA public
keys encapsulate two unsigned integers (modulus and exponent) as
DER values within the This function is called when creating X.509 SubjectPublicKeyInfo
values using the X509Key member functions, such as
