See Calculate RSA key fingerprint.

See also a relevant section of WinSCP FAQ on host keys.

You can execute the ssh-keygen on any *nix machine, you have an access to.

Or you can download Microsoft build of OpenSSH for Windows. On Windows 10 version 1803 or newer, you already have OpenSSH built-in. On older versions of Windows 10, it can be installed as an optional Windows feature. On older versions of Windows, you can just extract the ssh-keygen.exe from a .zip (latest release), no installation is need.

Show us a format of the public key you have. Or even a complete public key. It's public after all.
