class
EdECPublicKeySpec
extends Object
implements
KeySpec
A class representing elliptic curve public keys as defined in
RFC 8032: Edwards-Curve
Digital Signature Algorithm (EdDSA), including the curve and other
algorithm parameters. The public key is a point on the curve, which is
represented using an EdECPoint.
