Public constructor for use from outside this package.
Parameters: N the public shared modulus. g the generator. Y the public exponent of the ephemeral key.
Default constructor. Assumes that N and g are already validated.
Parameters: params an array of 3 values representing N, g and Y; the latter being the client's or server's public exponent.
Returns true if the designated object is an instance of
SRPPublicKeyand has the same SRP parameter values as this one.
Parameters: obj the other non-null SRP key to compare to.
Returns: true if the designated object is of the same type and
value as this one.
Returns the encoded form of this public key according to the designated format.
Parameters: format the desired format identifier of the resulting encoding.
Returns: the byte sequence encoding this key according to the designated format.
Throws: IllegalArgumentException if the format is not supported.
Returns the public exponent of the key as a BigInteger.
Returns: the public exponent of the key as a BigInteger.
A class method that takes the output of the encodePublicKey()
method of an SRP keypair codec object (an instance implementing
IKeyPairCodec for SRP keys, and re-constructs an instance of this
object.
Parameters: k the contents of a previously encoded instance of this object.
Throws: ArrayIndexOutOfBoundsException if there is not enough bytes, in
k, to represent a valid encoding of an instance of this object. IllegalArgumentException if the byte sequence does not represent a
valid encoding of an instance of this object.
