Anyone who accesses your private keyfile can then assume your identity on any SSH server you use to establish key-based authentication. Initializing a connection in SSH consists of: negotiating version of the protocol for using negotiated cryptographic algorithms and other options to use negotiate a one-time session key to encrypt the rest of the session to authenticate server host using its host key authenticate the user using a password, authenticating public keys or otherwise. If you generate the keys, do it Use the ssh keygen to store the keys in a safe place, so you can bypass the login prompt when you connect your instances. However, it is possible to specify which filename, location, and pathname whenever you create a private key. The option -i for the SSH client. Its function is similar to the username and password, but the keys are mainly used for automated processes and to implement simple login by sister em administrators and advanced users. Create a new key pair for authentication To create a new pair of keys, select the type of key to generate at the bottom of the screen (with SSH-2 RSA with 2048 bit key size, this is a good option for most) is ECDSA. Instead, while it may be invoked by the ssh add program, which then downloads the decrypted keys into the ssh agent, configures the following sentences x11-ssh-askpass to be invoked by the above-mentioned keychain script. The security has been improved by eliminating the need to save the password in the files and eliminating the possibility of a compromised server that steals the user password. The server already had the original message and session ID so that it could compare an MD5 hash generated by these values ​​and decide that the client must have the private key. If you want to use the key to access an external computer in an automated script, you can enter an empty password so that the script does not require any user interaction.
