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. VB.NET

Dim success As Boolean = 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).
Dim x As String = "1ccbe91c075fc7f4f033bfa248db8fccd3565de94bbfb12f3c59ff46c271bf83"
Dim y As String = "ce4014c68811f9a21a1fdb2c0e6113e06db7ca93b7404e78dc7ccd5ca89a4ca9"

Dim pubkey As New Chilkat.PublicKey
success = pubkey.LoadEcdsa("secp256r1",x,y)
If (success = False) Then
    Debug.WriteLine(pubkey.LastErrorText)
    Exit Sub
End If


Debug.WriteLine("Success.")
