Oct 06, 2018  Generate SSH Private and Public Keys in macOS Mojave. October 6, 2018 2 Comments. This guide goes through setting up SSH keys on macOS Mojave 10.14 back to Mac OSX 10.11 and also a secure password-less SSH connection between a local macOS workstation and a remote server also running a Linux variant operating system. The standard OpenSSH suite of tools contains the ssh-keygen utility, which is used to generate key pairs. Run it on your local computer to generate a 2048-bit RSA key pair, which is fine for most uses. Ssh-keygen The utility prompts you to select a location for the keys. To generate a new Key pair, run the following commands on your home computer. Open your terminal and run the following command under your username. local$ ssh-keygen -t rsa This creates a public/private keypair of the type (-t) rsa.

You can create keys directly from your account:

  1. Log in into your account as the master user or as an admin user.
  2. Pick the user you want to create keys for and choose the Generate SSH Keys button from the drop-down menu. This will create the .sftp folder in the home folder of the user, and the public key will be added to the authorized_keys file and placed inside the .sftp folder ( e.g. /.sftp/authorized_keys). You will be prompted to download the private key file.
  3. Import the private key into your SFTP software on your local computer.

You should now be able to connect without a password.

Linux / Mac OS X - Manual Key Creation (Experts Only)

  1. Open a terminal and use OpenSSH to generate a public/private key pair. You should not enter a password when prompted (e.g. just press return):
  2. Convert the public key to RFC-4716 format, which is the only format our SFTP server accepts for public keys:


    Prior to OpenSSH v5.4, there was a bug which allows for comments longer than 72 characters, which is in violation of the RFC-4716 spec. Our FTP server will reject such keys as invalid. If you're using a version of OpenSSH prior to v5.4, you should open the key file and delete any comment longer than 72 characters.

  3. Change the name of the public key to read authorized_keys.
  4. Using an SFTP client with a username and password, upload the RFC-4716 format key to your ExaVault SFTP server. It must be placed inside of a folder named .sftp in the home folder of the user (e.g. /.sftp/authorized_keys ).
  5. Import the private key into your SFTP software on your local machine. There are many ways to do this, depending on the software. For example, if you use sftp you would enter:

You should now be able to connect without a password.

Windows - Manual Key Creation (Experts Only)

Due to the multiple applications necessary to create an SSH key in Windows, we strongly recommend using an ExaVault-generated SSH key for Windows machines. However, ExaVault does support the use of SSH keys manually created in Windows as long as they are converted properly.

  1. Download and install the PuTTy application from http://www.putty.org/. Version 0.70 is the latest version. Install the 32-bit version of the application. When installing, use the default settings for installation.
  2. Start the PuTTyGen application. This application is installed as part of the PuTTy installation. Under the Key menu, verify that the key is set to SSH-2 RSA key. Under the Parameters section, confirm that the type of key is set to RSA. Confirm that the number of bits is set to 2048.
  3. Click the Generate button. When prompted move the mouse over the blank area in the application.
  4. Click the Save Public Key button. When prompted, name the file authorized_keys and make note of where you save this file.
  5. Click the Save Private Key button. Take note of the name and location of this file. When prompted, click the Yes button if you do not want to include a passphrase on the key.
  6. Convert the public key (the one you named authorized_keys) to a UNIX file format. The key will not be recognized by the server if it contains Windows line endings. Open the file in a text editor that can convert line endings from Windows to UNIX. Notepad++ is a free software that can convert Windows line endings to UNIX line endings. Save the file after converting the line endings.
  7. Using an SFTP client with a username and password, upload the authorized_keys file to your ExaVault SFTP server. It must be placed inside of a folder named .sftp in the home folder of the user (e.g. /.sftp/authorized_keys ).
  8. Import the private key into your SFTP software on your local machine. There are many ways to do this, depending on the software.

You should now be able to connect without a password.

Example SSH Keys

If you are having trouble generating your SSH keys, you can find an example pair here to verify that your keys are formatted correctly. These keys are for verification purposes only. Because both the public and private keys are provided in this example to anyone, please do not upload the public key to your SFTP server!

SSH Keys FAQ

Can I use multiple SSH keys with SFTP?

Yes! Simply append each additional public key into the authorized_keys file on the FTP server asdescribed above.

Can I use a key that was provided to me?

You may have a customer or client who already has an SSH key pair that you need to import.

You can upload a public key that was provided to you as long as it conforms to the RFC-4716 format. Often you will need to convert your key to the RFC-4716 format. To convert the key, see Steps 2 and 3 of the Linux/Mac OS X key creation instructions.

If the key was created on a Windows machine, you may need to edit the public key so that it does not contain Windows line endings using a text editor that can convert Windows line endings to UNIX line endings.

  1. Keyfile – It is the name of the existing key file to read at the time of changing the current key.
  2. –t keytype – The command specifies the type of key to creating. Its acceptable values are RSA and dsa.rsa1.
  3. -b bits – This command specifies a total number of bit in a particular key. 1024 is the perfect size for DSA key, while 2048 or 4096 are the perfect size for RSA keys.
  4. –q – The command suppresses the message about progress at the time of key generation.
  5. -C new-comment – The command will specify the comment to describe the key. It can be used for the new and/or existing key. Key operation is not affected by a comment. However, it is used to recognize the key owner, it’s not reliable completely as any value can be applied to it.
  6. –P – Using the command will update the passphrase of a key. Passphrase helps to encrypt the private key. As passphrase can’t add or update on a command line, it prompts a new passphrase tool to alter it.
  7. –old-passphrase-file – The old password of the key remains in this file. The command is used when the key is protected by a passphrase.
  8. –new-passphrase file – This command prompts the new passphrase of the key. It comes in the action either at the time of generating a new key or while applying –P command to change the passphrase.
  9. -O output-type – This command defines what to give in output. By default, the private key is the output.
