# [−][src]Function bulletproofs::util::scalar_exp_vartime

pub fn scalar_exp_vartime(x: &Scalar, n: u64) -> Scalar

Raises `x`

to the power `n`

using binary exponentiation,
with (1 to 2)*lg(n) scalar multiplications.
TODO: a consttime version of this would be awfully similar to a Montgomery ladder.
