Decrypting from RNCryptor-cs on swift 3 and RNCryptor gives me unknown header

[RBabb]

I have a string that I encrypted using RNCryptor-cs and trying to decrypt it on mac osx using RNCryptor decrypt but not having much luck. swift:

public func decrypt(ciphertext: String) -> String {
        do {
            let data = Data(base64Encoded: ciphertext)
            let originalData = try RNCryptor.decrypt(data: data!, withPassword: self.Salt)
            return String(data: originalData, encoding: .utf8)! as String
        } catch {
            self.recordLog(fileName: "error", Msg: "\(error)", Fnc: "decrypt")
            return ""
        }
    }

C#

static public string Encrypt(string strText)
        {
            try
            {
                return new Encryptor().Encrypt(strText, Salt);
            }
            catch (Exception e)
            {
                RecordLog("error", e.Message, "Tools:::Encrypt");
                return string.Empty;
            }
        }

Are they not compatible? Any suggestions how I can make it work? Or maybe I'm just having a bald moment. Any direction would be appreciated. Thank you.

respectively it works from MAC encrypt to PC decrypt but not PC encrypt to mac decrypt

What error are you receiving? Do you have an example of the output?

I am getting null output. And an error of unknown header. The salt (password) is the same. The only thing I think could be the issue is the ivlength.

"Unknown header" means that the data you're passing isn't in RNCryptor format. That usually means it's encoded somehow (like Base64). The first byte of the data you're passing to decrypt should be 03.

Found the issue.... It was in the RnCryptor-cs the default schema was version 2 changed private Schema defaultSchemaVersion = Schema.V2; to private Schema defaultSchemaVersion = Schema.V3; and all is well. Thanks.
