(Java) Load EC Public Key from X,Y Values (easier)
Demonstrates how to load an ECDSA public key from X and Y values using the LoadEcdsa method introduced in Chilkat v9.5.0.85.
import com.chilkatsoft.*;
public class ChilkatExample {
static {
try {
System.loadLibrary("chilkat");
} catch (UnsatisfiedLinkError e) {
System.err.println("Native code library failed to load.\n" + e);
System.exit(1);
}
}
public static void main(String argv[])
{
// Note: This example requires Chilkat v9.5.0.85 or greater.
boolean success;
// We have the following x and y values in hex (for an EC point on the P-256 curve).
String x = "1ccbe91c075fc7f4f033bfa248db8fccd3565de94bbfb12f3c59ff46c271bf83";
String y = "ce4014c68811f9a21a1fdb2c0e6113e06db7ca93b7404e78dc7ccd5ca89a4ca9";
CkPublicKey pubkey = new CkPublicKey();
success = pubkey.LoadEcdsa("secp256r1",x,y);
if (success == false) {
System.out.println(pubkey.lastErrorText());
return;
}
System.out.println("Success.");
}
}
