Generate RSA Key Pair on Windows

Those instructions apply to users who are receiving their statements via sFTP. If you elected to receive your statements in that way, you would first need to generate an RSA Key pair. Here is how to do that:

1. Download WinSCP and PuTTYgen.

2. Run the installer and make sure to check PuTTYgen (key generator) as one of the components to install.

3. Start WinSCP and PuTTYgen.

4. On PuTTYgen, click Generate.  Enter your sFTP username in the Key Comment field, select RSA as Type of key to generate, 2048 as Number of bits in generated key and click on the button Generate.

5. Click on "Save private key" and give the file a name (like private). Leave the extension as .ppk  ('ale.ppk', in the picture below is an example filename):

6. Open WinSCP, create a new connection and:
  • Select SFTP as File protocol.
  • Enter xfer.interactivebrokers.com in the Host name field.
  • Enter 32 in the Port number field.
 
7. Click on the button Advanced.

8. In the Advanced Site Settings screen, left side menu, expand SSH and select Authentication. Click on the button ... at the end of the field Private Key file and open the private key you previously saved at point 5):

9. Click on the button Display public key:
 
10. Click on the button Copy Key.

11. Open Notepad, press CTRL+V to paste the key string (which is one string of characters without spaces) and then save the file with the name public.key in a folder of your preference:


12. Send the file you saved at the previous step to us via Message Center ticket or email as per instructions on IBKB3842
 
13. In the WinSCP Window, click on "OK" in the information pop-up showing the key, then "OK" in the Advanced Site Settings screen, then click on Save to save the new connection you have created.
 
14. Once the IBKR Sales Engineering Team has configured the parameters for your connection on our servers, you will be able to access your SFTP repository by using the connection you have created.
