To change the passphrase, click on Load to load an existing key, then enter a new passphrase, and click Save private key to save the private key with the new passphrase. These instructions can also be used to add a passphrase to a key that was created without one. Just changing the passphrase is no substitute, but it is better than nothing. The Universal SSH Key Manager can automate this. It is recommended that all SSH keys be regenerated and changed periodically. Any larger organization should ensure they have proper provisioning and termination processes for SSH keys as part of their Identify and Access Management (IAM) practice. It works with legacy keys on traditional servers as well as dynamic and keyless elastic environments in the cloud. Universal SSH Key Manager can manage PuTTY keys in addition to OpenSSH and Tectia keys. In large quantities, SSH keys can become a massive security risk and they can violate compliance requirements. In larger organizations, the number of SSH keys on servers and clients can easily grow to tens of thousands, in some cases to millions of keys.

See configuring public key authentication for PuTTY. Configure PuTTY to use your private key file (here keyfile.ppk).

To install the public key, Log into the server, edit the authorized_keys file with your favorite editor, and cut-and-paste the public key output by the above command to the authorized_keys file. With both Tectia SSH and OpenSSH servers, access to an account is granted by adding the public key to a ~/.ssh/authorized_keys file on the server. Installing the public key as an authorized key on a server If keys are needed for automation (e.g., with WinSCP, then they may be left without a passphrase. We strongly recommended using a passphrase be for private key files intended for interactive use. It may be advisable to also save the public key, though it can be later regenerated by loading the private key (by clicking Load). You should save at least the private key by clicking Save private key. You can now specify a passphrase for the key. When complete, the public key should appear in the Window. This may take from several seconds to several minutes. Once the progress bar becomes full, the actual key generation computation takes place. As you move it, the green progress bar should advance. You may need to move the mouse for some time, depending on the size of your key. The exact way you are going to move your mouse cannot be predicted by an external attacker.

Putty uses mouse movements to collect randomness. Then click Generate, and start moving the mouse within the Window. To create a new key pair, select the type of key to generate from the bottom of the screen (using SSH-2 RSA with 2048 bit key size is good for most people another good well-known alternative is ECDSA).

Go to Windows Start menu → All Programs → PuTTY → PuTTYgen. For detailed installation instructions, see PuTTY installation instructions. There is no need for a separate PuTTYgen download. PuTTYgen is normally installed as part of the normal PuTTY.
