(AutoIt) RSA Sign with PKCS8 Encrypted Key
Demonstrates how to load a private key from an encrypted PKCS8 file and create an RSA digital signature.
; 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:
Local $bSuccess = $oPkey.LoadPkcs8EncryptedFile("privateKey.key","myPassword")
Local $sPkeyXml
; Get the private key in XML format:
$sPkeyXml = $oPkey.GetXml()
$oRsa = ObjCreate("Chilkat.Rsa")
; Import the private key into the RSA object:
$bSuccess = $oRsa.ImportPrivateKey($sPkeyXml)
If ($bSuccess <> True) Then
ConsoleWrite($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)
