My question is how to create a public key and private key with OpenSSL in windows and how to put the created public key in.crt file and the private one in.pcks8 file in order to use this two keys to sign a SAML assertion in Java. Thanks in advance. Openssl rsa digital-signature saml. Create a key pair. To create a key pair, at a command prompt, type the following command: sn –k file name In this command, file name is the name of the output file containing the key pair. The following example creates a key pair called sgKey.snk. Sn -k sgKey.snk. Generating the Public Key - Windows 1. At the command prompt, type the following: openssl rsa -in rsa.private -out rsa.public -pubout -outform PEM 2. The public key is saved in a file named rsa.public located in the same folder. Generating the Private Key - Linux 1. Open the Terminal. Navigate to the folder with the ListManager directory.

Generate RSA keys with SSH by using PuTTYgen

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.

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

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

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.

Create Public Key

  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.

There are three main ways to generate a public key in Windows. We've tried them all with Windows 7, but given the PuTTY tools are most popular, they are documented first. Whichever method you choose, email your generated key to your designated manager and they will notify you when your account has been created. Note, if you have multiple keys because you have multiple machines, or perhaps you have different keys for different software, send them all to us - we can set you up with as many keys as you want bound to your Code Enigma account.


This is a Free Open Source Software (FOSS) solution for Windows that allows Windows users to generate SSH keys and use them to access Linux servers via an SSH connection.

Generate Ssh Public Key From Private Key

[1] Download and run the PuTTY 'Installer' from this page:

[2] Generate a private and public key pair:

  • Go to the Windows Start menu -> All Programs -> PuTTY and open PuTTYgen
  • Click the 'Generate' button and PuTTYgen will ask you to make some random movement with your mouse until it has enough random data to generate a secure key for you
  • Click the 'Save private key' button and save the resulting file somewhere safe and only accessible by you!

[3] Export Public key to the Linux server:

In the grey box at the top, entitled 'Public key for pasting into OpenSSH authorized_keys file', there will be a string of nonsense. Copy all of this string into an email and send it to us, as per the opening instruction on this page.

That's it, you're done!

Git Bash

This is a light-weight terminal client for using Git from the command line on Windows. It's a sort of scaled down version of CygWin, and one of the nice things about it is it permits normal 'Terminal' access to Linux servers.

[1] Download and run the latest version from this page:

The installer will open msysGit when it completes, follow the instruction to create a shortcut:

[2] Generate a private and public key pair:

Generate Public Key From Ppk File

Follow steps 1 and 2 of the GitHub instructions found here:

At step 3, use the 'clip' command as instructed, but paste the result into an email and send it.


If none of the above works, there's also Bitvise, which is not FOSS, but is freely available for personal use, and even individual use within an organisation, so it's a good and legal option.

[1] Download the Bitvise SSH client software:

[2] Generate a private and public key pair:

  • click the link titled 'User keypair manager' in the Login tab;
  • click the button [Generate New ...];
  • choose ssh-rsa and 1024bits;
  • you can enter passphrase or leave it empty
  • click the button [Generate]

This passphrase is not sent to the remote host, and it is only used to protect your private key. Otherwise, anyone who has access to your private key can authenticate to your account automatically.

[3] Export Public key to the Linux server:

Generate Public Key From Key File Download

  • Go to the 'User keypair manager';
  • click the keypair in the slots;
  • click the button [Export];
  • chose 'Export public key' and 'OpenSSH format';
  • click the button [Export];

The result should look something like:

Email just this public part to Code Enigma, as per instructions.
