Load EC Public Key from X,Y Values (easier)

See more ECC Examples

Demonstrates how to load an ECDSA public key from X and Y values using the LoadEcdsa method introduced in Chilkat v9.5.0.85. Swift

func chilkatTest() {
    var success: Bool = false

    // Note: This example requires Chilkat v9.5.0.85 or greater.

    // We have the following x and y values in hex (for an EC point on the P-256 curve).
    var x: String? = "1ccbe91c075fc7f4f033bfa248db8fccd3565de94bbfb12f3c59ff46c271bf83"
    var y: String? = "ce4014c68811f9a21a1fdb2c0e6113e06db7ca93b7404e78dc7ccd5ca89a4ca9"

    let pubkey = CkoPublicKey()!
    success = pubkey.loadEcdsa(curveName: "secp256r1", qx: x, qy: y)
    if success == false {
        print("\(pubkey.lastErrorText!)")
        return
    }

    print("Success.")
