Load EC Public Key from X,Y Values

See more ECC Examples

Demonstrates how to load an EC public key from X and Y values. Go

    success := false

    // We have the following x and y values in base64 (for an EC point on the P-256 curve).
    x := "Dn7uB1O7kgk74G6qfQwFJESeDnxO6lLjGZFWZJE16tw"
    y := "iOWA5DInzK6nuUGvHJbMVq1Dpj248FqSV2teN3HzmhU"

    // Build a JWK that looks like this:

    // {
    //   "kty": "EC",
    //   "crv": "P-256",
    //   "x": "Dn7uB1O7kgk74G6qfQwFJESeDnxO6lLjGZFWZJE16tw",
    //   "y": "iOWA5DInzK6nuUGvHJbMVq1Dpj248FqSV2teN3HzmhU"
    // }

    json := chilkat.NewJsonObject()
    json.UpdateString("kty","EC")
    json.UpdateString("crv","P-256")
    json.UpdateString("x",x)
    json.UpdateString("y",y)

    // Load from the JWK.
    pubkey := chilkat.NewPublicKey()
    success = pubkey.LoadFromString(*json.Emit())
    if success == false {
        fmt.Println(pubkey.LastErrorText())
        json.DisposeJsonObject()
        pubkey.DisposePublicKey()
        return
    }

    fmt.Println("Success.")

    json.DisposeJsonObject()
    pubkey.DisposePublicKey()
