nptracker NPS-DL API (Driving Licence Check is valid using NPS-DL API ) HEX encoded binary string

Question

I have to check the suspect vehicles in South Africa, For this South Africa provides us with API. In API we have to pass a Driving license number or image that I am confused about.

In API we have to pass a hex-encoded binary string. See this URL: https://api.nptracker.co.za/docs/#/NPS-DL/NPS-DL

But this is not working (I am doing RSA public encryption with 128 bytes).

let gettBas64Text = self.getEncryptedPassword("02/0990016092185")      debugPrint(gettBas64Text)
    
    func getEncryptedPassword(_ getPass: String) -> String? {
        let password = getPass
          let publicKey:PublicKey!
            let encrypted :EncryptedMessage
            let clear:ClearMessage
            do {
                publicKey = try PublicKey(pemNamed: "public", in: .main)
     
     
                do {
                    clear = try ClearMessage(string: password, using: .utf8)
     
                    do {
     
                        encrypted = try clear.encrypted(with: publicKey, padding: .PKCS1SHA256)
     
     
                        let base64String = encrypted.base64String
     
                        return base64String
     
                    }
                    catch{
                        print("Unable to start encrypted-- \(error)")
                    }
                }
                catch{
                    print("Unable to start clear")
                }
            }
            catch{
                print("Unable to start PublicKey-- \(error)")
            }
             return nil
        }
     
        static func getKeyStringFromPEM(name: String) -> String {
            let bundle = Bundle.main
     
            let keyPath = bundle.path(forResource: name, ofType: "pem")!
            let keyString = try! String(contentsOfFile: keyPath, encoding: .utf8)
            let keyArray = keyString.components(separatedBy: "\n") //Remove new line characters
     
            var keyOutput : String = ""
     
            for item in keyArray {
                if !item.contains("-----") { //Example: -----BEGIN PUBLIC KEY-----
                    keyOutput += item //Join elements of the text array together as a single string
                }
            }
            return keyOutput
        }
