Class XECPublicKeySpec
java.lang.Object
java.security.spec.XECPublicKeySpec
- All Implemented Interfaces:
- KeySpec
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.
