Generate RSA keys with SSH by using PuTTYgen

May 02, 2014  We will next see the RSA algorithm, which uses public key cryptography and is the basis of the PuTTYgen program. RSA Algorithm. As already stated, ‘RSA’- stands for R on Rivest, Adi S hamir and Leonard A dleman, who designed the algorithm. Most cryptographic algorithms involve tremendous amount of mathematics and the RSA algorithm is no exception. Generate SSH keys using the PuTTY key generator (PuTTYgen): Procedure. Start PuTTYgen by clicking Start Programs PuTTY PuTTYgen. The PuTTY Key Generator panel is displayed. Click SSH-2 RSA as the type of key to generate. Note: Leave the number of bits in a generated key. Puttygen on Linux - SSH Key Generator. This page is about PuTTYgen on Linux. For the Windows version.t keytype Specifies to the type of a new key to generate. Acceptable values include rsa and dsa. Rsa1 is also supported to generate legacy SSH-1 keys. To create an SSH2 key using PuTTYGen, do the following: Double-click puttygen.exe, select SSH2 RSA key type, key strength is 1024 by default. Click 'Generate'. Next, move your mouse around the blank area to create 'randomness' in the key generation.

One effective way of securing SSH access to your cloud server is to usea public-private key pair. This means that a public key is placed onthe server and a private key is placed on your local workstation.Using a key pair makes it impossible for someone to log in by using justa password, as long as you set up SSH to deny password-basedauthentication.

Generate Rsa Key Using Puttygen

This article provides steps for generating RSA keys by using PuTTYgen onWindows for secure SSH authentication with OpenSSH.

May 05, 2019 To generate an SSH key pair on Windows using PuTTYgen perform the following steps: Start the PuTTYgen tool, by double-clicking on its.exe file or going to the Windows Start menu → PuTTY (64-bit) → PuTTYgen. For “Type of key to generate” leave the default RSA. The “Number of bits in a generated key”, 2048 is sufficient for most people. 'ssh-rsa AAAAB3. 6yIK9Nbw rsa-key-20150709' This works fine, however I would like to attempt to create such a file using OpenSSL instead. Mostly because I just want to convert/create a private key later in PKCS#8 format using: openssl pkcs8 -topk8 -v2 des3. I read this can be done independent of the public key after the fact. To create an SSH2 key using PuTTYGen, do the following: Double-click puttygen.exe, select SSH2 RSA key type, key strength is 1024 by default. Click 'Generate'. Next, move your mouse around the blank area to create 'randomness' in the key generation.

Generate keys

In Windows, use PuTTYgen to generate your public and private keys.

  1. If needed, download PuTTYgen from the PuTTY download page.(PuTTYgen might have been installed previously with PuTTY or WinSCP.)
  2. Launch the program, and then click the Generate button.The program generates the keys for you.
  3. Enter a unique key passphrase in the Key passphrase andConfirm passphrase fields.For additional information about using passphrases,see Log in with a SSH Private Key on Windows.
  4. Save the public and private keys by clicking the Save public keyand Save private key buttons.
  5. From the Public key for pasting into OpenSSH authorized_keys filefield at the top of the window, copy all the text (starting with ssh-rsa)to your clipboard by pressing Ctrl-C.You need this key available on your clipboard to paste eitherinto the public key tool in the Control Panel or directly into theauthorized keys on your cloud server.

Use the key pair

You can use the RSA key pair in the following ways.

Specify your SSH key when creating a new cloud server

Generate Private Key Using Puttygen

When you create a cloud server, you can assign a public key from the list of keys.If your key is not already in the list, you may add it, and then assign it.

Add a new public key to the list

  1. Under Advanced Options on the Create Server page, click Manage SSHKeys.
  2. Select public key for the cloud server from the SSH Keys listand click Add Public Key.
  3. Enter the key name, select the region, and paste the entire publickey into the Public Key field. Then click Add Public Key.
  4. Go back to the Create Server page, and confirm that your key is listedin the SSH Key list.

Assign a public key

  1. Under Advanced Options on the Create Server page, select the publickey you want to use from the SSH key drop-down menu.
  2. When you are done specifying the all the other details for the server,click Create Server.

Assign your SSH Key to an existing cloud server

To make use of your newly generated RSA key pair, you must tell PuTTY touse it when connecting to your cloud server.

  1. To edit the file (or create it), run the following command on the cloud server:

  2. Paste the text onto its own line in the file.

    You must have the key available in your clipboard to paste it. The key and itsassociated text (the ssh-rsa identified at the start and the comment at the end)must be on one line in the file. If the text is word-wrapped onto multiple linesan error might occur when connecting.

  3. If you created the authorized_keys file, change its permissionsafter you’re done editing it by running the following command:

  4. Open PuTTY, and go to the SSH > Auth section.

  5. Browse to the location of the key file, and load the private key.

  6. Go to the Session page, and save the session. This saves the configurationso that PuTTY uses the key every time that you connect to your cloudserver.

After you save your session, your key is loaded automatically when youconnect to your server.
