Class Ed25519

java.lang.Object

com.wireguard.crypto.Ed25519

public final class Ed25519
extends java.lang.Object

Implementation of Ed25519 signature verification.

This implementation is based on the ed25519/ref10 implementation in NaCl.

It implements this twisted Edwards curve:

 -x^2 + y^2 = 1 + (-121665 / 121666 mod 2^255-19)*x^2*y^2
