Passwordless SSH

A user can create an SSH identity and tell other hosts to trust it without asking for a password: the password never goes through the network.

The identity has a public and a private part.

• The public part is transmitted through the network.
• The private part is kept locally under a passphrase and used to sign the public part.

The passphrase can be kept in local memory so that it only needs to be entered once.
