I had a need to use SVN over encrypted line, so after some research I came up with this solution. I won't go into details on how to install SVN or SSH server, I assume you already got that working. This small guide was written for one of the users, that needed to configure their SVN client to use SSH on non standart port, so here it is:

1. Download the required SSH software for Windows (I assume you already have TortoiseSVN). Clicky 1.
2. Use the SSH keys (not covered on how to make them in this mini-guide) Clicky 2.
3. Change network setting in TortoiseSVN, to use different port for SSH:

   <path_to>\bin\TortoisePlink.exe -P <custom_ssh_port> -l <working_ssh_username>
   

   Clicky 3.
4. Use the checkout function. The URL will need to have to be a little bit different than usual:

   svn+ssh://<hostname>/<full_path_of_svn_on_the_server>
   

   Clicky 4.
5. And that should be working! Clicky 5.
