(AutoIt) RSA Sign utf-8 Byte Representation of String

Demontstrates how to sign the utf-8 byte representation of a string.

Note: This example requires Chilkat v11.0.0 or greater.

Local $bSuccess = False

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

; Load an RSA private key for signing.
$oPrivKey = ObjCreate("Chilkat.PrivateKey")
$bSuccess = $oPrivKey.LoadEncryptedPemFile("qa_data/pem/rsa_passwd.pem","passwd")
If ($bSuccess = False) Then
    ConsoleWrite($oPrivKey.LastErrorText & @CRLF)
    Exit
EndIf

$oRsa = ObjCreate("Chilkat.Rsa")
$bSuccess = $oRsa.UsePrivateKey($oPrivKey)
If ($bSuccess = False) Then
    ConsoleWrite($oRsa.LastErrorText & @CRLF)
    Exit
EndIf

Local $sOriginalData = "This is the string to be hashed an RSA signed."

; Indicate that we want the utf-8 byte representation of the string to be signed
$oRsa.Charset = "utf-8"

; We want the RSA signature in base64 format
$oRsa.EncodingMode = "base64"

Local $sigBase64 = $oRsa.SignStringENC($sOriginalData,"sha256")
ConsoleWrite($sigBase64 & @CRLF)
