Decdh.md10 Some libraries do not check if the elliptic curve points received from another
11 party are points on the curve. Encodings of public keys typically contain the
12 curve for the public key point. If such an encoding is used in the key exchange
14 the shared ECDH secret are using the same curve.
26 ECDH does not check if the points are on the curve.
30 The ECDH implementation does not check if the point is on the curve.
32 on the same curve. It performs a point multiplication \\(x \cdot Y\\) over the
33 curve specified by the public key.
47 * check that public and private key use the same curve
53 If possible I also check if the points are on the curve after point
