RSA Sign with PKCS8 Encrypted Key

Demonstrates how to load a private key from an encrypted PKCS8 file and create an RSA digital signature. AutoIt

Local $bSuccess = False

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

$oPkey = ObjCreate("Chilkat.PrivateKey")

; Load the private key from an RSA PEM file:
$bSuccess = $oPkey.LoadPkcs8EncryptedFile("privateKey.key","myPassword")

$oRsa = ObjCreate("Chilkat.Rsa")

; Import the private key into the RSA object:
$bSuccess = $oRsa.UsePrivateKey($oPkey)
If ($bSuccess = False) Then
    ConsoleWrite($oRsa.LastErrorText & @CRLF)
    Exit
EndIf

; Return the signature in hex
$oRsa.EncodingMode = "hex"

Local $strData = "This is the string to be signed."

; Sign the string using the sha-1 hash algorithm.
; Other valid choices are "md2", "sha256", "sha384", "sha512",  and "md5".
Local $sHexSig = $oRsa.SignStringENC($strData,"sha-1")

ConsoleWrite($sHexSig & @CRLF)
