The client must begin the SSH connection by initiating the TCP handshake with the server, ensuring a secured symmetric connection, verifying whether the identity displayed by the server match previous records (typically recorded in an RSA key store file), and presenting the required user credentials to authenticate the connection. There are two stages to establishing a connection: first both the systems must agree upon encryption standards to protect future communications, and second, the user must authenticate themselves. If the credentials match, then the user is granted access.
