Important! You must save the private key, because you need it to connect to your remote machine. You can use a key without a passphrase, so you are not always been asked for a password if you use your key.
Type the same passphrase in the Confirm passphrase field. Type a passphrase in the Key passphrase field.When the progress bar is full, PuTTYgen generates your key pair. Move your mouse in the area below of the progress bar.For Type of key to generate, select SSH-2 RSA.To generate an SSH key with PuTTYgen, follow these steps: PuTTYgen is the utility whith which one you generate your SSH key. You can download PuTTY from When you install the PuTTY client, you also install the PuTTYgen utility. PuTTY is an SSH client for Windows and you can generate your SSH keys. Generate an SSH Key on Windowsįor Windows you need an additional program to create an SSH Key. This is the key you install on your server and you can share. Never share this key, keep it private on your machine. Your public key has been saved in /home/username/.ssh/id_rsa.pub. Your identification has been saved in /home/username/.ssh/id_rsa. The same here: do not enter a passphrase, just hit enter. Let the path as suggested and just hit enter at this question.Įnter passphrase (empty for no passphrase):

How to generate SSH Keys Generate an SSH Key on Mac-OS or Linux It is possible, that a user can authenticate on all servers, where his public key is installed. The user’s private key is the one that grants the authentication.Īnother advantage of SSH-keys is, that you do not need different passwords to log in to different servers. This method consists on authentication via asymmetric cryptography. The preferred way is to leave remote access open, because you need it, but you close the user/password authentication and you log in with an SSH-key. They make bruteforce attacks and if the password is weak, they will get access to your server. Access with username and password is not a very secure way, with SSH Keys it’s not just easier, its also more secure. SSH is a basic tool for system administrators to access your server.
