You cannot generate private key from public key but you can generate public key from the private key using puttygen. As @alfasin mentioned if you could generate the private key from public key then RSA would be useless and this would make you vulnerable to attack.FYI the public key is used for encryption and private key is used for decryption. Dec 01, 2016 putty ssh private + public key windows and linux with puttygen. Easily setup PuTTY SSH keys for passwordless logins. Generate SSH Key Pairs to Access Linux instances in the Oracle Cloud. To use WinSCP, you need the private key that you generated in Convert Your Private Key Using PuTTYgen. You also need the public DNS address of your Linux instance. You also need the public DNS address of your Linux instance.
You can generate an SSH key on Windows using the PuTTY SSH client. You can download PuTTY for free from this URL.
To generate a key with PuTTY, you should:
- Download and start the puttygen.exe generator.
- In the 'Parameters' section choose SSH2 DSA and press Generate.
- Move your mouse randomly in the small screen in order to generate the key pairs.
- Enter a key comment, which will identify the key (useful when you use several SSH keys).
- Type in the passphrase and confirm it. The passphrase is used to protect your key. You will be asked for it when you connect via SSH.
- Click 'Save private key' to save your private key.
- Click 'Save public key' to save your public key.

-->To use an open SSH connection from your development machine to the server VM in your Azure Stack Hub instance that hosts your web app, you might need to create a Secure Shell (SSH) public and private key pair.
In this article, you create your keys and then use them to connect to your server. You can use an SSH client to get a bash prompt on the Linux server or use a Secure FTP (SFTP) client to move files to and from the server.

Create an SSH public key on Windows
In this section, you use PuTTY Key Generator to create a public SSH key and private key pair to use when you create a secure connection to Linux machines in your Azure Stack Hub instance. PuTTY is a free terminal emulator that can allow you to connect to a server via SSH and Telnet.
- Open PuTTY Key Generator.
- Under Parameters, select RSA.
- In the Number of bits in a generated key box, enter 2048.
- Select Generate.
- In the Key area, generate some random characters by moving the cursor over the blank area.
- Enter a Key passphrase and confirm it in the Confirm passphrase box. Note your passphrase for later use.All the raw material for calculating public/private key, but I don't want the raw material.ExportCspBlob(x) provides a key, but when I try to verify it online, the key pair verification fails.So, is there any way to create RSA public private key pair in powershell without using any external programs, which can be directly copy-pasted into a certificate format(the one with -BEGIN PRIVATE KEY- stuff)? It should be able to encrypt/decrypt data on any online public/private key verification service.Purpose- Strictly Educational. I'm very well aware that you shouldn't export your private key online for security purposes.So far I've triedssh-keygen and $RSA = New-Object System.Security.Cryptography.RSACryptoServiceProvider(2048)System.Convert::ToBase64String($rsa.ExportCspBlob(1))System.Convert::ToBase64String($rsa.ExportCspBlob(0))System.Security.Cryptography.RSACryptoServiceProvider creates P, Q etc. Generate ssh key pair windows. I want to generate an RSA public private key pair in powershell without using external software and I want to test it.
- Select Save public key, and save it to a location where you can access it.
- Select Save private key, and save it to a location where you can access it. Remember that it belongs with the public key.
Your public key is stored in the text file you saved. The text looks like the following:
When an application requests the key, you copy and paste the entire contents of the text file.
Connect with SSH by using PuTTY
When you install PuTTY, you have both PuTTY Key Generator and an SSH client. In this section, you open the SSH client, PuTTY, and configure your connection values and SSH key. If you're on the same network as your Azure Stack Hub instance, you connect to your VM.
Before you connect, you will need:
- PuTTY
- The IP address and username for the Linux machine in your Azure Stack Hub instance that uses an SSH public key as the Authentication type.
- Port 22 to be open for the machine.
- The public SSH key that you used when you created the machine.
- The client machine that runs PuTTY to be on the same network as your Azure Stack Hub instance.
- Open PuTTY.
- In the Host Name (or IP address) box, enter the username and public IP address of the machine (for example, [email protected]).
- Validate that the Port is 22 and the Connection type is SSH.
- In the Category tree, expand SSH and Auth.
- Next to the Private key file for authentication box, select Browse, and then search for the private key file (<filename>.ppk) of your public and private key pair.
- In the Category tree, select Session.
- Under Saved Sessions, enter a name for the session, and then select Save.
- In the Saved Sessions list, select the name of your session, and then select Load.
- Select Open. The SSH session opens.
Connect with SFTP with FileZilla
To move files to and from your Linux machine, you can use FileZilla, an FTP client that supports Secure FTP (SFTP). FileZilla runs on Windows 10, Linux, and macOS. The FileZilla client supports FTP, FTP over TLS (FTPS), and SFTP. It is open-source software that's distributed free of charge under the terms of the GNU General Public License.
Set your connection
- Download and install FileZilla.
- Open FileZilla.
- Select File > Site Manager.
- In the Protocol drop-down list, select SFTP - SSH File Transfer Protocol.
- In the Host box, enter the public IP address for your machine.
- In the Logon Type box, select Normal.
- Enter your username and password.
- Select OK.
- Select Edit > Settings.
- In the Select page tree, expand Connection, and then select SFTP.
- Select Add key file, and then enter your private key file (for example, <filename>.ppk).
- Select OK.
Open your connection
- Open FileZilla.
- Select File > Site Manager.
- Select the name of your site, and then select Connect.
