- All Implemented Interfaces:
A class representing elliptic curve public keys as defined in RFC 7748, including the curve and other algorithm parameters. The public key is a particular point on the curve, which is represented using only its u-coordinate. A u-coordinate is an element of the field of integers modulo some value that is determined by the algorithm parameters. This field element is represented by a BigInteger which may hold any value. That is, the BigInteger is not restricted to the range of canonical field elements.
public XECPublicKeySpec(AlgorithmParameterSpec params, BigInteger u)Construct a public key spec using the supplied parameters and u coordinate.
params- the algorithm parameters
u- the u-coordinate of the point, represented using a BigInteger which may hold any value
public AlgorithmParameterSpec getParams()Get the algorithm parameters that define the curve and other settings.
- the parameters
public BigInteger getU()Get the u coordinate of the point.
- the u-coordinate, represented using a BigInteger which may hold any value
