EdECPublicKeySpec
class EdECPublicKeySpec : 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.
Summary
| Public constructors |
|

|
| Public methods |
| NamedParameterSpec |
Get the algorithm parameters that define the curve and other settings.
|
| EdECPoint |
Get the point representing the public key.
