![]() 1: Install Linux-like software onto your Windows machine To ensure that people who really know what they’re doing with SSH/SFTP, like Linux system administrators, can help troubleshoot any problems you encounter when generating and using keypairs, a best practice is to use Linux-like software to initiate the generation of your keypair, even if you intend to use it from a Windows machine. Therefore, the tooling that people find most familiar for generating a “keypair” runs on Linux. This is still the case for many Linux system administrators. The first thing you’ll want to do is generate a “private key” file and a corresponding “public key” file, which together are known as a “keypair.”īack in the day, most people who were remotely accessing Linux servers over SSH/SFTP were already typing at the command prompt of a computer running Linux. In this article, we’ll covering making a “keypair” if you don’t yet have one, and using it to SSH/SFTP into a Linux server, when your desktop computer runs Windows. Together, these are known as a “ keypair.” It’ll be your job to keep a copy of your “ private key” on the desktop computer from which you’ll be SSH’ing/SFTP’ing into the Linux machine.The Linux server will already have a copy of your “ public key” on file (because you’ll have e-mailed it ahead of time to the server’s system administrator).SSH and SFTP are protocols typically used for “remoting into” a server running the Linux operating system, much like you might use the “Remote Desktop” protocol to remotely operate a Windows machine.Īlthough it can be authenticated into by username and password, many Linux servers force you to SSH/SFTP into them with a username and “key.” 2: Import your Windows-style private key.4: Back up your new passphrase and private keys.2: Re-passphrase your Windows-style private key.1: Re-passphrase your Linux-style private key.Changing the secret passphrase on your private keys.Test your Windows key against a Linux server.Make a Windows-friendly copy of the Linux-style private key.Test your Linux key against a Linux server.Secure your private key with a passphrase.2: Generate a Linux-style private key file.1: Install Linux-like software onto your Windows machine.With the script.txt containing open command at its beginning: Psftp.exe -pw password -hostkey aa:bb:cc. See also Verifying the host key section below.įor example the following PSFTP command-line: While they are not required, it is still recommended to add them as otherwise WinSCP may choose to use a different (better) host key algorithm and the checksum will not match (the same is actually true for PSFTP).Įxample: open -hostkey="ssh-rsa 2048 aa:bb:cc." With WinSCP, you should include key type and size in the signature. Specify the expected hostkey using -hostkey switch in an open command in the script. Specify the private key using -privatekey switch in an open command in the script. Specify the password in a session URL in an open command in the script. Specify the port number in a session URL in an open command in the script. Specify the username in a session URL in an open command in the script. You should better use a Generate Session URL/Code function and use the generated open command in the script. Though this makes the script dependent on GUI configuration (see below). Import your PuTTY stored session to WinSCP and use an open sessname command in the script. ![]() Use an option batch on command at the beginning of the script (to counter the default option batch abort). Use an option echo on command at the beginning of the script. The following table shows how to convert some psftp.exe the username and the hostname in a session URL in an open command in the script. In your command that runs psftp.exe, substitute the psftp.exe with.
