Function mul [src]

Multiply a Curve25519 point by a scalar without clamping it. Return error.IdentityElement if the resulting point is the identity element or error.WeakPublicKey if the public key is a low-order point.

Prototype

pub fn mul(p: Curve25519, s: [32]u8) (IdentityElementError || WeakPublicKeyError)!Curve25519

Parameters

p: Curve25519s: [32]u8

Source

  pub fn mul(p: Curve25519, s: [32]u8) (IdentityElementError || WeakPublicKeyError)!Curve25519 {
    _ = try p.clearCofactor();
    return try ladder(p, s, 256);
}
