SSH secures information with the use of a private and public key. To generate RSA keys, on the command line, enter: ssh-keygen -t rsa.The Secure SHell (SSH) protocol is used to securely access remote servers. To set up public key authentication using SSH on a Linux or macOS computer: Log into the computer youll use to access the remote host, and then use command-line SSH to generate a key pair using the RSA algorithm. You will need to 'downgrade' your idrsa file using the folloing command in the Terminal app: ssh-keygen -p -m PEM -f /.ssh/idrsa. If you are running a recent version of macOS, including Mojave. Dreamweaver does not like the the SSH Key format generated by the latest version of OpenSSH and the ssh-keygen untility.The private key should be kept private (hence the name) anybody who has the private key can impersonate the person who generated it and steal their private information. Not only do SSH keys help to protect your data, they add convenience. This checking continues as information is sent to you from the server. So when you connect to the remote server, the server confirms your identity by seeing if your private key unlocks the lock.
Ssh Download PuTTYgen OnTo utilize it, go to Finder and then opt for Go -> utilities from the top menu. Mac OS has a built-in command-line SSH client known as Terminal. Below is the detailed guide to download PuTTYgen on Mac operating system. Key Generation and Set up with Linux / Mac / Windows with MobaXtermDownload PuTTYgen for Mac.Open the terminal/command prompt on your computer (for Windows open terminal in MobaXterm). I encourage you to use a passphrase, it is a good security habit. If you don't set a passphrase anyone that has access to your private key file can read it. You'll be prompted for a passphrase when you create the keys. Mac and Linux will look slightly different but follow the same process.On macOS, we can use ssh-keygen utility to generate a new key pair. This is to prevent others from seeing your password). ( NOTE: The terminal will not show the password while typing. Make sure to remember this password for later. Hit enter to continue.Next it will prompt you to enter a passphrase and confirm it. Enter file in which to save the key ( /home/RITusername/.ssh/id_rsa):The default file is usually fine. The terminal will respond with: Generating public/private rsa key pair. The fingerprint of the key and it’s randomart image is also displayed. Nano /home/username/.ssh/id_rsa/pub) and see the keys. You can open these files in a text editor (e.g. If all is right you will not have to enter your RIT password, but instead the passphrase for the key generated. Now the terminal will say that a key was added and ask you to try logging into the machine you just copied the public key to. Next the terminal will ask you to enter your password for the remote machine. The terminal may show you the key fingerprint and ask if you still want to install it. Ssh/id_rsa.pub If the ssh-copy-id command is not available on your machine, skip the following steps and go to the "Alternative to ssh-copy-id heading". It does the same thing as ssh-copy-id.Run this command in your terminal: ~] cat ~/.ssh/id_rsa.pub | - > ~/.ssh/authorized_keys" To install this command on your Mac follow the instructions provided here: If you do not want to or cannot install the shh-copy-id command use this alternative. See the "Using ssh-agent heading".The ssh-copy-id command may not be available on older versions of the Mac OS. You will be asked to move your mouse around the area to generate randomness. Leave all the settings as they are and click Generate. It was installed along with PuTTY so there is no need to download it. Search for PuTTYgen and open the application. Next time you log into the remote machine you will be prompted to enter the passphrase for the private key and then you will be able to access the machine.Key Generation and Setup on Windows with PuTTY Fate go emulator macUse PuTTY to SSH into the remote machine and enter your password. Do not close out of this window. Do not share this file with others. Save the private key as id_rsa.ppk somewhere safe on your computer. These keys can be named anything you want, id_rsa is just the default when generating from the command line. Save the public key as id_rsa.pub somewhere on your computer. It is the authorized_keys file in the vim text editor within PuTTY.Copy the public key from the PuTTYgen window and paste it to the end of the authorized_file. Open the authorized_keys file with a text editor of your choice (the command below opens the key in vim):A window similar to this will pop up. Mkdir ~/.ssh chmod 700 ~/.sshIf the authorized_keys file does not exists:Touch ~/.ssh/authorized_keys chmod 600 ~/.ssh/authorized_keys Because of this, the compiler throws a message that the file already exists. In the picture below, the user has already created the. Ssh file has not been created type the code below. It will return you to the regular PuTTY terminal from before you opened the authorized_keys file.Open PuTTY again and in the menu to the side of the window navigate to Connection → SSH → AuthClick Browse and find where you stored the private key that corresponds to the public key you just pasted into authorized_keys.Go back to the Session tab and enter information as you would regularly.When the terminal is open it will say: Authenticating with public key “rsa-key-#” Passphrase for key “rsa-key-#”Enter the passphrase for the key and you are set.To avoid entering your passphrase every time you use PuTTY for SSH, you can use PuTTY's Pageant. Commands for text editors (such as how to save in vim) are located here. To save and exit out of the authorized_keys file in vim type ESC, and then :wq (save and quit). You must open it from the PuTTYgen window by clicking Load, selecting the corresponding private key, and entering the passphrase.Paste key at the end of the authorized_keys file opened in vim:Save the authorized_keys file and log out of the terminal. Find the private key you want to convert Open PuTTYgen and click Conversions → Import Key in the top menu bar. You must have the public key already on the remote machine. Follow the key generation and setup instructions for Windows with PuTTY. FastX Web Client Windows with PuTTY SetupFastX does not support PuTTY's format for private SSH keys, so we need to first convert them into OpenSSH format. ![]() MobaKeyGen is very similar to PuTTYgen, so you can use the instructions under Key Generation and Set up on Windows with PuTTY. If you are using MobaXterm you cannot use the key generated by ssh-keygen, you must use the generator which is found under Tools → MobaKeyGen. Now that you have connected with the key once, the next time you connect you will only be prompted for the key’s passphrase.Pageant is a tool included with PuTTY that runs as a background process and enters the passphrase for the private keys for you. The first time you use the key you will be prompted to enter your RIT password. ![]() To add a key press Add Key. Or just double-click the icon in the tray. Click either View Keys or Add Key to open the Pageant Key List window. The next time you open Pageant, you must add the key again.Using ssh-agent (Mac / Linux / MobaXterm)The ssh-agent is a background process that automatically enters the passphrase for private keys. Make sure when you are done using SSH to log into the remote machines you right click the Pageant Icon and click Exit. Now if you use PuTTY with SSH keys you will not have to find the private key or enter the passphrase. You will then be prompted to enter the passphrase for the private key. It must be a PuTTY generated key (ppk). Now you can connect through FastX as you normally would without entering your RIT password or passphrase for the private key. You will then be asked to enter the passphrase for the private key. Follow the instructions under Key Generation and Set Up with Linux / Mac / MobaXterm to do this.Open your terminal and starting the program by running:Note: Backquote (`) is located under tilde (~), the backquote is not a single quote (')
