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. Xbase++

LOCAL nSuccess
LOCAL x
LOCAL y
LOCAL oPubkey

nSuccess := 0

//  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"

oPubkey := CreateObject("Chilkat.PublicKey")
nSuccess := oPubkey:LoadEcdsa("secp256r1", x, y)
IF (nSuccess == 0)
    ? oPubkey:LastErrorText
    oPubkey:destroy()
    RETURN
ENDIF

? "Success."

oPubkey:destroy()
