Curve25519 scalar multiplication r = n * p
with context.
A shared secret is computed from the local secret key n
and another party's public key p
and put into r
. The same shared secret is generated when the other party combines its private key with the local public key.
ctx | Context. | |
[out] | r | Resulting curve point. |
[in] | n | Scalar factor. |
[in] | p | Point factor. |
r
may be same as n
.
