Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

' 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 = "1ccbe91c075fc7f4f033bfa248db8fccd3565de94bbfb12f3c59ff46c271bf83"
y = "ce4014c68811f9a21a1fdb2c0e6113e06db7ca93b7404e78dc7ccd5ca89a4ca9"

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.PublicKey")
set pubkey = CreateObject("Chilkat.PublicKey")
success = pubkey.LoadEcdsa("secp256r1",x,y)
If (success = 0) Then
    outFile.WriteLine(pubkey.LastErrorText)
    WScript.Quit
End If

outFile.WriteLine("Success.")

outFile.Close
