The simplest way to generate a key pair is to run ssh-keygen without arguments. In this case, it will prompt for the file in which to store keys. From Tools, select Create or Import SSH Keys. From the PuTTY Key Generator dialog, click the Generate button. As the SSH key generates, hover your mouse over the blank area in the dialog. It may take a minute or two.

This guide contains a description of setting up public key authentication for use with WinSCP. You may want to learn more about public key authentication or SSH keys instead.
- Configure Server to Accept Public Key
Advertisement
Before starting you should:
- Have WinSCP installed;
- Know how to connect to the server without public key authentication.
If you do not have a key pair yet, start with generating new key pair.
Connect to your SSH server using WinSCP with the SSH protocol, using other means of authentication than public key, e.g. typically using password authentication.
Once logged in, configure your server to accept your public key. That varies with SSH server software being used. The most common SSH server is OpenSSH.
You can use Session > Install Public Key into Server command on the main window, or Tools > Install Public Key into Server command on SSH > Authentication page page on Advanced Site Settings dialog. The functionality of the command is similar to that of OpenSSH ssh-copy-id
command.
Or you can configure the key manually:
Generate An Ssh Key Linux
- Navigate into a
.ssh
subdirectory of your account home directory. You may need to enable showing hidden files to see the directory. If the directory does not exists, you need to create it first. - Once there, open a file
authorized_keys
for editing. Again you may have to create this file, if this is your first key. - Switch to the PuTTYgen window, select all of the text in the Public key for pasting into OpenSSH authorized_keys file box, and copy it to the clipboard (
Ctrl+C
). Then, switch back to the editor and insert the data into the open file, making sure it ends up all on one line. Save the file. WinSCP can show you the public key too. - Ensure that your account home directory, your
.ssh
directory and fileauthorized_keys
are not group-writable or world-writable. Recommended permissions for.ssh
directory are700
. Recommended permissions forauthorized_keys
files are600
. Read more about changing permissions.
There are some specifics when setting up the public key authentication on OpenSSH server on Windows.
- Save a public key file from PuTTYgen, and copy that into the
.ssh2
subdirectory of your account home directory. - In the same subdirectory, edit (or create) a file called
authorization
. In this file you should put a line likeKey mykey.pub
, withmykey.pub
replaced by the name of your key file.
Ssh Key Setup
For other SSH server software, you should refer to the manual for that server.
When configuring session, specify path to your private key on SSH > Authentication page of Advanced Site Settings dialog.
Alternatively, load the private key into Pageant.
How To Generate An Ssh Key
Cloud providers have typically their own mechanism to setup a public key authentication to virtual servers running in the cloud.

- Amazon EC2;
- Google Compute Engine;
- Microsoft Azure.
