See more Ed25519 Examples

Demonstrates how to load an Ed25519 private key from raw hex bytes.

Note: This example requires Chilkat v9.5.0.83 or greater.

Local $bSuccess = False

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

$oPrivKey = ObjCreate("Chilkat.PrivateKey")

; We have the hexidecimal encoded bytes of the private key and public key:
Local $sPrivKeyHex = "d4ee72dbf913584ad5b6d8f1f769f8ad3afe7c28cbf1d4fbe097a88f44755842"
Local $sPubKeyHex = "19bf44096984cdfe8541bac167dc3b96c85086aa30b6b6cb0c5c38ad703166e1"

; Load these values into the Chilkat private key object:
$bSuccess = $oPrivKey.LoadEd25519($sPrivKeyHex,$sPubKeyHex)
If ($bSuccess = False) Then
    ConsoleWrite($oPrivKey.LastErrorText & @CRLF)
    Exit
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 = ObjCreate("Chilkat.PrivateKey")
$bSuccess = $oPrivKey2.LoadEd25519($sPrivKeyHex,"")

; Let's get the public key to see that it computed the same value.
$oSbPubKeyHex = ObjCreate("Chilkat.StringBuilder")
$sPrivKeyHex = $oPrivKey2.GetRawHex($oSbPubKeyHex)
ConsoleWrite("computed public key = " & $oSbPubKeyHex.GetAsString() & @CRLF)

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