public final class Curve25519
extends Object

Implementation of the Curve25519 elliptic curve algorithm. This implementation is based on that from arduinolibs: https://github.com/rweather/arduinolibs Differences in this version are due to using 26-bit limbs for the representation instead of the 8/16/32-bit limbs in the original. References: http://cr.yp.to/ecdh.html, RFC 7748

Since:

0.9.36 moved from router to core in 0.9.38

Method Detail

eval

public static void eval(byte[] result,
                        int offset,
                        byte[] privateKey,
                        byte[] publicKey)

Evaluates the Curve25519 curve.

Parameters:

result - Buffer to place the result of the evaluation into.

offset - Offset into the result buffer.

privateKey - The private key to use in the evaluation.

publicKey - The public key to use in the evaluation, or null if the base point of the curve should be used.
