What Version of SSH Does OpenSSH Use?
To see what version of SSH your Windows computer is using, you can use the command “sshd -v” in your command prompt. You can also check the version by connecting to a remote server via SSH protocol in verbose mode. SSH is a common method of remote access. It requires a public/private key pair and is considered secure. OpenSSH is the default protocol on Windows.
The OpenSSH protocol contains a server and a client. Microsoft has incorporated both into their Windows operating system and provides them as default programs. These tools allow Windows users to connect to secure devices and transfer data securely. However, Windows users should ensure that they don’t install the SSH client unless they’re using it for business. If you are installing OpenSSH on a Windows computer, you should also check if it conflicts with the internal SSH server that Developer mode uses. You should also ensure that the SSH server doesn’t block port 22.
OpenSSH on Windows reads public keys from the C:ProgramDatasshadministratorsauthorized_keys file. If you don’t have this file, you must create it. Make sure to give it the proper ACL (Access Control List) before you can use it. Then, run ssh-keygen to generate a new key pair for your account.
The first step to install the OpenSSH client is to enable the Developers mode on your operating system. If you’re using Windows 10, this should take only a few minutes and should be the only option available. Once enabled, you can start installing the OpenSSH client and begin working with the secure connection. If you don’t have Developers Mode enabled, you’ll need to download it separately.

OpenSSH configuration files
OpenSSH has configuration files for both server and client settings. OpenSSH is open-source and is added to Windows Server and Windows Client operating systems, starting with Windows Server 2019 and Windows 10 (build 1809). As a result, documentation for OpenSSH configuration files is not repeated here. Client configuration files and can be found on the ssh_config manual page and for OpenSSH Server configuration files can be found on the sshd_config manual page. Further Windows-specific OpenSSH Server configuration is detailed in OpenSSH Server configuration for Windows.
In Windows, the OpenSSH Client (ssh) reads configuration data from a configuration file in the following order:
- By launching ssh.exe with the -F parameter, specifying a path to a configuration file and an entry name from that file.
- A user’s configuration file at %userprofile%\.ssh\config.
- The system-wide configuration file at %programdata%\ssh\ssh_config.
Open SSH Server (sshd) reads configuration data from %programdata%\ssh\sshd_config by default, or a different configuration file may be specified by launching sshd.exe with the -f parameter. If the file is absent, sshd generates one with the default configuration when the service is started.
