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. Unicode C

#include <C_CkPublicKeyW.h>

void ChilkatSample(void)
    {
    BOOL success;
    const wchar_t *x;
    const wchar_t *y;
    HCkPublicKeyW pubkey;

    success = 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).
    x = L"1ccbe91c075fc7f4f033bfa248db8fccd3565de94bbfb12f3c59ff46c271bf83";
    y = L"ce4014c68811f9a21a1fdb2c0e6113e06db7ca93b7404e78dc7ccd5ca89a4ca9";

    pubkey = CkPublicKeyW_Create();
    success = CkPublicKeyW_LoadEcdsa(pubkey,L"secp256r1",x,y);
    if (success == FALSE) {
        wprintf(L"%s\n",CkPublicKeyW_lastErrorText(pubkey));
        CkPublicKeyW_Dispose(pubkey);
        return;
    }

    wprintf(L"Success.\n");


    CkPublicKeyW_Dispose(pubkey);
