On macOS, your agent uses your keychain, so pass in `-K` to ssh-add, e.g. If your key is in a non-standard location, you can manually specify it with `ssh-add /path/to/the/ssh/key`. The ssh-agent is usually automatically started on Linux, and you can load the key into your agent by typing `ssh-add`. If you do not want to have to type your key's passphrase every time, you can load the key into your SSH agent once. Then you can invoke `ssh somename` and it will pass in all of the above options. Create and/or append to the file ~/.ssh/config on your local computer and enter the following: Host somename Since you may not want to type that every time, you can configure an ssh host alias.
HOW TO SET UP SSH ON MAC PASSWORD
You can explicitly tell your ssh program to use your ssh key and not your password with `ssh -o preferredauthentications=publickey. See the UNIX instructions for these steps above as they are identical. Click Save public key to save your public key.
Click Save private key to save your private key.The passphrase is used to protect your key and you will be asked for it when you connect via SSH using public key authentication. You may choose to enter a key comment which can be used by you to identify the key (useful when you use several SSH keys).You will need to move your mouse about in the small window area in order to generate randomness that the process requires. In the Parameters section choose SSH2 RSA as the key type and press Generate.Start the puttygen.exe program included with the Putty installer.Otherwise see the more brief step-by-step instructions below.
HOW TO SET UP SSH ON MAC HOW TO
You may choose to follow the thorough Putty documentation directly on how to create an SSH keypair on Windows.
HOW TO SET UP SSH ON MAC DOWNLOAD
Download the complete Windows installer rather than just the putty.exe file. The most popular Windows SSH client today is Putty which is available from. Otherwise, on the remote computer: $ cat id_ed25519.pub > ~/.ssh/authorized_keys On Windows If you are not the owner of the remote account you will need to have the owner perform this step. Once the key has been transfered to the remote machine, its contents will need to be appended to ~/.ssh/authorized_keys within the remote account. The public key file is actually just a text file. You can transfer the public key in any number of ways, such as by emailing it to the owner of the remote account or an administrator, or FTP, SCP, or SFTP if you have access. Once you have generated the key pair, you will need to transfer the public key, e.g. For security reasons you should not use empty passphrases. If you already have a keypair with the standard names, you may choose to create additional keypairs with different names. Your public key has been saved in $HOME/.ssh/id_ed25519.pub. Your identification has been saved in $HOME/.ssh/id_ed25519. Generating public/private ed25519 key pair.Įnter file in which to save the key ($HOME/.ssh/id_ed25519):Įnter passphrase (empty for no passphrase): You can generate keys with the ' ssh-keygen' command: $ ssh-keygen -t ed25519 This is why you must keep the private key to yourself, otherwise people who have a copy of it can pass through all the doors in which you left your public key. The door will only open if you have the associated private key as you approach. Think of this process as leaving a real key (the public key) in a remote door. The other key, the public key, is put into the remote account by the owner of that account (which may be you) or by the server administrator. The private key stays on the machine you will connect from which is usually the machine where it is created (for example, your laptop).
You create a pair of files known as "keys", one private and one public, to facilitate this process. This is useful if you'd like to not have to enter the password to an account you own and access frequently, or if you need to connect to a shared account where you are not its owner and do not know its password. SSH key pairs allow users to connect to remote accounts without having to use the password of the remote account.
