(AutoIt) RSA Encrypt and Decrypt StringsSee more RSA ExamplesAutoIt sample code to RSA public-key encrypt and decrypt strings using public and private keys.Note: This example requires Chilkat v11.0.0 or greater.
Local $bSuccess = False ; This example assumes the Chilkat API to have been previously unlocked. ; See Global Unlock Sample for sample code. $oRsa = ObjCreate("Chilkat.Rsa") ; This example also generates the public and private ; keys to be used in the RSA encryption. ; Normally, you would generate a key pair once, ; and distribute the public key to your partner. ; Anything encrypted with the public key can be ; decrypted with the private key. The reverse is ; also true: anything encrypted using the private ; key can be decrypted using the public key. ; Generate a 2048-bit key. Chilkat RSA supports ; key sizes ranging from 512 bits to 4096 bits. $oPrivKey = ObjCreate("Chilkat.PrivateKey") $bSuccess = $oRsa.GenKey(2048,$oPrivKey) If ($bSuccess = False) Then ConsoleWrite($oRsa.LastErrorText & @CRLF) Exit EndIf $oPubKey = ObjCreate("Chilkat.PublicKey") $oPrivKey.ToPublicKey($oPubKey) Local $sPlainText = "Encrypting and decrypting should be easy!" ; Start with a new RSA object to demonstrate that all we ; need are the keys previously exported: $oRsaEncryptor = ObjCreate("Chilkat.Rsa") ; Encrypted output is always binary.
