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. DataFlex

Use ChilkatAx-win32.pkg

Procedure Test
    Boolean iSuccess
    String x
    String y
    Handle hoPubkey
    String sTemp1

    Move False To iSuccess

    // 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).
    Move "1ccbe91c075fc7f4f033bfa248db8fccd3565de94bbfb12f3c59ff46c271bf83" To x
    Move "ce4014c68811f9a21a1fdb2c0e6113e06db7ca93b7404e78dc7ccd5ca89a4ca9" To y

    Get Create (RefClass(cComChilkatPublicKey)) To hoPubkey
    If (Not(IsComObjectCreated(hoPubkey))) Begin
        Send CreateComObject of hoPubkey
    End
    Get ComLoadEcdsa Of hoPubkey "secp256r1" x y To iSuccess

        Get ComLastErrorText Of hoPubkey To sTemp1
        Showln sTemp1
