To generate an SSH-2 RSA key pair and save it in PuTTY's own format (you will be prompted for the passphrase): puttygen -t rsa -C 'my home key' -o mykey.ppk To generate a larger (2048-bit) key: puttygen -t rsa -b 2048 -C 'my home key' -o mykey.ppk To change the passphrase on a key (you will be prompted for the old and new passphrases). The Key passphrase and Confirm passphrase boxes allow you to choose a passphrase for your key. The passphrase will be used to encrypt the key on disk, so you will not be able to use the key without first entering the passphrase. When you save the key, PuTTYgen will check that the Key passphrase and Confirm passphrase boxes both contain exactly the same passphrase, and will refuse to save the key otherwise. You will see the PuTTY key generator dialog box on your screen You will find a “Generate” button in that dialog. Clicking on it will lead to generating the keys for you. Now you will need to add a unique key passphrase in the Key passphrase and Confirm passphrase field. For Type of key to generate, select SSH-2 RSA. For Number of bits in a generated key, enter 2048. Click Generate. When prompted, move the mouse around the specified section of the window. Optional: Enter a passphrase for the private key in Key passphrase and Confirm passphrase.
You can generate an SSH key on Windows using the PuTTY SSH client. You can download PuTTY for free from this URL. Generating ssh keys on mac windows 10.
To generate a key with PuTTY, you should:
Ssh Key Without Passphrase
Powershell Passphrase Generator
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.
