(AutoIt) RSA Sign with PKCS8 Encrypted KeySee more RSA ExamplesDemonstrates 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) |
