Questions tagged [ssh-agent]

'ssh-agent' is a program that used together with OpenSSH or similar SSH programs provides a secure way of storing the private key. Man Page https://www.freebsd.org/cgi/man.cgi?query=ssh-agent&apropos=0&sektion=0&manpath=FreeBSD+13.1-RELEASE+and+Ports&arch=default&format=html

A password-based authentication process (in the common example of OpenSSH) may be vulnerable to brute-force attacks, if no mechanism is in place to detect them. To mitigate this lack of security, ssh supports public key authentication.

In order to log in securely to a remote system via a secure shell, a private key/public key pair is generated. The private key is stored on the local machine. The public key is stored on the target machine in the $HOME/.ssh/authorized_keys file. Public keys are not sensitive information and may be known to anybody, whereas the private key needs to be protected very carefully by a strong passphrase.

ssh-agent remembers the decrypted private key so that the user does not need to type it every time he or she wants to connect or send data to the server.
