Be sure to follow the instructions carefully. If the SSH Key you copied starts with "- BEGIN SSH2 PUBLIC KEY .", it is in the wrong format. NOTE: PuTTY and OpenSSH use different formats for public SSH keys. Now add the public key hash to the authorized key file on the target server (may need to have someone do this for you), restart sshd and you can begin logging into that specific server with keys.Right-click again in the same text field and choose Copy.Right-click in the text field labeled Public key for pasting into OpenSSH authorized_keys file and choose Select All.Click the Save private key button & choose whatever filename you'd like (you can save it in the same location as the public key, but it should be a location that only you can access and that you will NOT lose! If you lose your keys and have disabled username/password logins, you will no longer be able log in!).Click the Save public key button & choose whatever filename you'd like (some users create a folder in their computer named my_keys).Optional: Type a passphrase in the Key passphrase field & re-type the same passphrase in theConfirm passphrase field (if you would like to use your keys for automated processes, however, you should not create a passphrase).your e-mail address home office etc.) - the key comment is particularly useful in the event you end up creating more than one key pair In the Key comment field, enter any comment you'd like, to help you identify this key pair, later (e.g.A private/ public key pair has now been generated.

How to Generate a Public and Private Keypair Windows Users
In terms of server administration, any device that has your public key installed will be able to authenticate you using your private key when you send it. The public key is like the keyhole, as it can be installed on any door or device that the matching private key should have access to. This key should belong only to you and can be used anywhere that has a matching keyhole. The private key is much like the key that you have to a building or a car. Using an analogy related to real keys and door access mechanisms, it is easy to explain PKC at a high level. PKC is based on using special algorithms based on the mathematical concept of logarithms in order to generate two specific keys for a user. They keys themselves are based on a security design referred to as Public Key Cryptography (PKC). Public and private keys are a method of user authentication that is prevalent in the field of server administration.
