Class DSSPublicKey
- DSAKey, DSAPublicKey, Key, PublicKey
public class DSSPublicKey
implements PublicKey, DSAPublicKey
An object that embodies a DSS (Digital Signature Standard) public key.
DSSPublicKey(BigInteger p, BigInteger q, BigInteger g, BigInteger y) - Trivial constructor.
|
boolean | equals(Object obj) - Returns
true if the designated object is an instance of
DSAPublicKey and has the same DSS (Digital Signature Standard)
parameter values as this one.
|
byte[] | getEncoded(int format) - Returns the encoded form of this public key according to the designated
format.
|
BigInteger | getY()
|
static DSSPublicKey | valueOf(byte[] k) - A class method that takes the output of the
encodePublicKey()
method of a DSS keypair codec object (an instance implementing
IKeyPairCodec for DSS keys, and re-constructs an
instance of this object.

DSSPublicKey
public DSSPublicKey(BigInteger p,
BigInteger q,
BigInteger g,
BigInteger y)
Trivial constructor.
p
- the public modulus.q
- the public prime divisor of p-1
.g
- a generator of the unique cyclic group Z*
p
.y
- the public key part.
equals
public boolean equals(Object obj)
Returns true
if the designated object is an instance of
DSAPublicKey
and has the same DSS (Digital Signature Standard)
parameter values as this one.
- equals in interface DSSKey
obj
- the other non-null DSS key to compare to.
true
if the designated object is of the same type and
value as this one.
getEncoded
public byte[] getEncoded(int format)
Returns the encoded form of this public key according to the designated
format.
- getEncoded in interface DSSKey
format
- the desired format identifier of the resulting encoding.
- the byte sequence encoding this key according to the designated
format.
getY
public BigInteger getY()
valueOf
public static DSSPublicKey valueOf(byte[] k)
A class method that takes the output of the
encodePublicKey()
method of a DSS keypair codec object (an instance implementing
IKeyPairCodec
for DSS keys, and re-constructs an
instance of this object.
k
- the contents of a previously encoded instance of this object.
