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