With a secure shell (SSH) key pair, you can create virtual machines (VMs) in Azure that use SSH keys for authentication, eliminating the need for passwords to sign in. This article shows you how to quickly generate and use an SSH public-private key file pair for Linux VMs. You can complete these steps with the Azure Cloud Shell, a macOS or Linux host, the Windows Subsystem for Linux, and other tools that support OpenSSH.

Note

Jul 09, 2019  This will download a PEM file, containing your Private Key, Certificate and CA-Bundle files (if they were previously imported to the server). The files can be opened in any text editor, such as Notepad. Synology NAS DSM. When generating a CSR in Synology DSM, the Private Key is provided to you in a zip file on the last step. The key code is contained within a server.key file, that can be opened. Enter the name of the.pem file for example: my-certificate.pem. Step by step from generating key to login: Generate the key with $ ssh-keygen -t rsa -b 2048 -v and when asked to enter file in which to save the key, type my-certificate and when asked to enter passphrase, press Enter (empty passphrase) and confirm by Enter. Back to PSCP, users are required to use the private key they generated while converting the.pem file to the.ppk file. Converting a.pem file to a.ppk using PuTTYgen may now seem simple. The above information also briefs users on using PuTTY’s SSH client to connect virtual servers with local machines. Press generate and follow instructions to generate (public/private) key pair. Create a new 'authorizedkeys' file (with Notepad): Copy your public key data from the 'Public key for pasting into OpenSSH authorizedkeys file' section of the PuTTY Key Generator, and paste the key data to the 'authorizedkeys' file. PuTTY does not natively support the private key format for SSH keys. PuTTY provides a tool named PuTTYgen, which converts keys to the required format for PuTTY. You must convert your private key (.pem file) into this format (.ppk file) as follows in order to connect to your instance using PuTTY.

VMs created using SSH keys are by default configured with passwords disabled, which greatly increases the difficulty of brute-force guessing attacks.

Supported SSH key formats

Azure currently supports SSH protocol 2 (SSH-2) RSA public-private key pairs with a minimum length of 2048 bits. Other key formats such as ED25519 and ECDSA are not supported.

Create an SSH key pair

Use the ssh-keygen command to generate SSH public and private key files. By default, these files are created in the ~/.ssh directory. You can specify a different location, and an optional password (passphrase) to access the private key file. If an SSH key pair with the same name exists in the given location, those files are overwritten.

The following command creates an SSH key pair using RSA encryption and a bit length of 4096:

If you use the Azure CLI to create your VM with the az vm create command, you can optionally generate SSH public and private key files using the --generate-ssh-keys option. The key files are stored in the ~/.ssh directory unless specified otherwise with the --ssh-dest-key-path option. The --generate-ssh-keys option will not overwrite existing key files, instead returning an error. In the following command, replace VMname and RGname with your own values:

Provide an SSH public key when deploying a VM

To create a Linux VM that uses SSH keys for authentication, specify your SSH public key when creating the VM using the Azure portal, Azure CLI, Azure Resource Manager templates, or other methods:

Generate Pem File From Private Key To Computer

If you're not familiar with the format of an SSH public key, you can display your public key with the following cat command, replacing ~/.ssh/id_rsa.pub with the path and filename of your own public key file if needed:

A typical public key value looks like this example:

If you copy and paste the contents of the public key file to use in the Azure portal or a Resource Manager template, make sure you don't copy any trailing whitespace. To copy a public key in macOS, you can pipe the public key file to pbcopy. Similarly in Linux, you can pipe the public key file to programs such as xclip.

The public key that you place on your Linux VM in Azure is by default stored in ~/.ssh/id_rsa.pub, unless you specified a different location when you created the key pair. To use the Azure CLI 2.0 to create your VM with an existing public key, specify the value and optionally the location of this public key using the az vm create command with the --ssh-key-values option. In the following command, replace VMname, RGname, and keyFile with your own values:

If you want to use multiple SSH keys with your VM, you can enter them in a space-separated list, like this --ssh-key-values sshkey-desktop.pub sshkey-laptop.pub.

SSH into your VM

With the public key deployed on your Azure VM, and the private key on your local system, SSH into your VM using the IP address or DNS name of your VM. In the following command, replace azureuser and myvm.westus.cloudapp.azure.com with the administrator user name and the fully qualified domain name (or IP address):

If you specified a passphrase when you created your key pair, enter that passphrase when prompted during the login process. The VM is added to your ~/.ssh/known_hosts file, and you won't be asked to connect again until either the public key on your Azure VM changes or the server name is removed from ~/.ssh/known_hosts.

If the VM is using the just-in-time access policy, you need to request access before you can connect to the VM. For more information about the just-in-time policy, see Manage virtual machine access using the just in time policy.

.pem SSL Creation Instructions

SSL .pem files (concatenated certificate container files), are frequently required for certificate installations when multiple certificates are being imported as one file.

This article contains multiple sets of instructions that walk through various .pem file creation scenarios.

Creating a .pem with the Entire SSL Certificate Trust Chain

Generate Pem File From Private Key Tool

  1. Log into your DigiCert Management Console and download your Intermediate (DigiCertCA.crt), Root (TrustedRoot.crt), and Primary Certificates (your_domain_name.crt).

  2. Open a text editor (such as wordpad) and paste the entire body of each certificate into one text file in the following order:

    1. The Primary Certificate - your_domain_name.crt
    2. The Intermediate Certificate - DigiCertCA.crt
    3. The Root Certificate - TrustedRoot.crt

    Make sure to include the beginning and end tags on each certificate. The result should look like this:

    In the git bash terminal type ssh-keygen -t rsa. This will generate public and private key pair Go to the location of the keys (I'd recommend using git bash for it) and open the public key (with cat, for example), copy it Paste the public key on your github account using Account-SSH Keys-Add key. Sep 26, 2019  Generating an SSH key. To generate an SSH key with PuTTYgen, follow these steps: Open the PuTTYgen program. For Type of key to generate, select SSH-2 RSA. Click the Generate button. Move your mouse in the area below the progress bar. When the progress bar is full, PuTTYgen generates your key. Generating a new SSH key. Open Terminal Terminal Git Bash. Paste the text below, substituting in your GitHub email address. $ ssh-keygen -t rsa -b 4096 -C ' youremail@example.com '. This creates a new ssh. When you're prompted to 'Enter a file in which to save the key,' press Enter. Generate an SSH Key on Windows Windows environments do not have a standard default unix shell. External shell programs will need to be installed for to have a complete keygen experience. The most straight forward option is to utilize Git Bash. Generate ssh key in git. Generating Your SSH Public Key Many Git servers authenticate using SSH public keys. In order to provide a public key, each user in your system must generate one if they don’t already have one.
