//  This example assumes the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

oPrivKey := CreateObject("Chilkat.PrivateKey")

//  We have the hexidecimal encoded bytes of the private key and public key:
cPrivKeyHex := "d4ee72dbf913584ad5b6d8f1f769f8ad3afe7c28cbf1d4fbe097a88f44755842"
cPubKeyHex := "19bf44096984cdfe8541bac167dc3b96c85086aa30b6b6cb0c5c38ad703166e1"

//  Load these values into the Chilkat private key object:
nSuccess := oPrivKey:LoadEd25519(cPrivKeyHex, cPubKeyHex)
IF (nSuccess == 0)
    ? oPrivKey:LastErrorText
    oPrivKey:destroy()
    RETURN
ENDIF

//  ---------------------------------------------------------------
//  We don't actually need the public key.  If we pass an empty string for the public key,
//  Chilkat will automatically compute it.
oPrivKey2 := CreateObject("Chilkat.PrivateKey")
nSuccess := oPrivKey2:LoadEd25519(cPrivKeyHex, "")

//  Let's get the public key to see that it computed the same value.
oSbPubKeyHex := CreateObject("Chilkat.StringBuilder")
cPrivKeyHex := oPrivKey2:GetRawHex(oSbPubKeyHex)
? "computed public key = " + oSbPubKeyHex:GetAsString()

//  The output should be:
//  computed public key = 19bf44096984cdfe8541bac167dc3b96c85086aa30b6b6cb0c5c38ad703166e1
