## Class OwlCurves

- java.lang.Object
- - org.bouncycastle.crypto.agreement.owl.OwlCurves

-     public class OwlCurves
      extends java.lang.Object

  Standard pre-computed elliptic curves for use by Owl. (Owl can use pre-computed elliptic curves or prime order groups, same as DSA and Diffie-Hellman.)

  This class contains some convenient constants for use as input for constructing `OwlClient`s and `OwlServer`.

  The prime order groups below are taken from NIST SP 800-186, "Recommendations for Discrete Logarithm-based Cryptography: Elliptic Curve Domain Parameters", published by NIST.
