How to Set Up SSH Keys Between Windows 10 and Linux?

If you're setting SSH on different ports, you should treat it like any other SSH connection between two Linux machines. Placing your public key in the `authorized_keys` file should work fine for Windows to Linux SSH connections. Just ensure the SSH config is set correctly.

Creating the keys with Git isn't recommended. Normally, you would use `ssh-keygen`. Then, just make sure to copy the public part to the `authorized_keys` on your server. If you're adamant about using different ports, ensure your SSH config is allowing that. It may require permissions adjustments to work efficiently.

You can use `scp` to transfer your public keys the long way; here's how:

```
scp C:UsersUser.ssh*.pub user@hostname:/home/user/
```
And don't forget you can create a config file in your `.ssh` folder on Windows for easier access.

Just a heads up, using different ports for SSH might complicate things without offering much benefit. You can use `ssh-copy-id` to copy your public key to your Linux server, simplifying the setup. Make sure your `sshd_config` is set up correctly and check your file permissions on the `authorized_keys` file as well.

Are you just trying to generate keys? You can use this command: `ssh-keygen`. Also, for specific configurations, consider using a `known_hosts` file to manage settings per host.

To link your Windows machine with the Linux server, make sure you copy the public key to the server using a command like this:

```
Windows:
scp -P .ssh/*.pub username@remote:
Linux:
cat ~/.ssh/*.pub >> ~/.ssh/authorized_keys
```
That should do the trick!
