Deprecated: see getEncoded(int).
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.
See Also: DHKeyPairRawCodec
A class method that takes the output of the encodePublicKey()
method of a DH keypair codec object (an instance implementing
IKeyPairCodec for DSS 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.
