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

Local $bSuccess = 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).
Local $sX = "1ccbe91c075fc7f4f033bfa248db8fccd3565de94bbfb12f3c59ff46c271bf83"
Local $sY = "ce4014c68811f9a21a1fdb2c0e6113e06db7ca93b7404e78dc7ccd5ca89a4ca9"

$oPubkey = ObjCreate("Chilkat.PublicKey")
$bSuccess = $oPubkey.LoadEcdsa("secp256r1",$sX,$sY)
If ($bSuccess = False) Then
    ConsoleWrite($oPubkey.LastErrorText & @CRLF)
    Exit
EndIf

ConsoleWrite("Success." & @CRLF)
