Use crypto/elliptic to select standard curves like P256 and perform point operations for cryptographic math.
Use crypto/elliptic to select a standard curve like P256 and perform point operations such as scalar multiplication.
package main
import (
"crypto/elliptic"
"fmt"
)
func main() {
curve := elliptic.P256()
x, y := curve.ScalarBaseMult([]byte{0x01})
fmt.Println(x, y)
}
Note: For key exchange, prefer crypto/ecdh; for signing, prefer crypto/ecdsa.
The crypto/elliptic package in Go lets you work with standard elliptic curves used in encryption. You pick a curve like P256 and use it to do math on points, which is the foundation for secure digital signatures and key exchanges. Think of it as a calculator specifically designed for the math behind modern security protocols.
