Does public key go on server or client?
In SSH, the public key cryptography is used in both directions (client to server and server to client), so two key pairs are used. One key pair is known as a host (server) key, the other as a user (client) key.
How does client get public key?
It uses a symmetric session key which is negotiated and calculated independently by both peers. PKI is only used in SSL to authenticate the peers to each other. In any case your questions about ‘generating’ a public/private keypair at runtime don’t make sense.
What is public key and private key in SSH?
The private key is secret, known only to the user, and should be encrypted and stored safely. The public key can be shared freely with any SSH server to which the user wishes to connect.
Why is a private key required from s _ client?
During the SSL/TLS handshake, the server sends its certificate (in clear) and proves to the client that it has the corresponding private key using an authenticated key exchange. In your case, you also want to use client-certificate authentication.
Can a server assign a public key to a user?
The server administrator can then assign the public key to the user’s account. This approach ensures that the client is the only entity to ever possess the private key, and removes the need to securely deliver the private key to the client.
What happens if the client does not have the public key?
If the client doesn’t have the public key, or has a different public key you will get a scary warning. If the server doesn’t have the clients public key, you will not be allowed in. You as the user are the one to provide the information that you are you when you log in.
Why do you need a private key for a certificate?
Certificates on their own are only public pieces of information. What links a public key certificate to the name it contains is the fact that whoever has legitimate control over that name (e.g. your name or your server’s name) also has the private key for it.
