(PowerBuilder) Load EC Public Key from X,Y Values (easier)
Demonstrates how to load an ECDSA public key from X and Y values using the LoadEcdsa method introduced in Chilkat v9.5.0.85.
integer li_rc
integer li_Success
string x
string y
oleobject loo_Pubkey
// 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"
loo_Pubkey = create oleobject
// Use "Chilkat_9_5_0.PublicKey" for versions of Chilkat < 10.0.0
li_rc = loo_Pubkey.ConnectToNewObject("Chilkat.PublicKey")
if li_rc < 0 then
destroy loo_Pubkey
MessageBox("Error","Connecting to COM object failed")
return
end if
li_Success = loo_Pubkey.LoadEcdsa("secp256r1",x,y)
if li_Success = 0 then
Write-Debug loo_Pubkey.LastErrorText
destroy loo_Pubkey
return
end if
Write-Debug "Success."
destroy loo_Pubkey
