(AutoIt) RSA Encrypt and OpenSSL Decrypt

Demonstrates how to use Chilkat to RSA encrypt, and then use OpenSSL to decrypt.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows

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

$oRsa = ObjCreate("Chilkat.Rsa")

Local $bSuccess = $oRsa.GenerateKey(2048)

Local $oPrivKey = $oRsa.ExportPrivateKeyObj()
$bSuccess = $oPrivKey.SavePkcs8PemFile("qa_output/privKey.pem")

$oRsa.EncodingMode = "base64"
Local $sPlainText = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz01234567890"
Local $bUsePrivateKey = False
Local $sEncryptedStr = $oRsa.EncryptStringENC($sPlainText,$bUsePrivateKey)

$oBd = ObjCreate("Chilkat.BinData")
$oBd.AppendEncoded($sEncryptedStr,"base64")
$bSuccess = $oBd.WriteFile("qa_output/enc.dat")

; The OpenSSL command to decrypt is:
; openssl pkeyutl -in enc.dat -inkey privKey.pem -keyform PEM -pkeyopt rsa_padding_mode:pkcs1 -decrypt
