ssh-keygen is a standard component of the Secure Shell (SSH) protocol suite found on Unix, Unix-like and Microsoft Windows computer systems used to establish secure shell sessions between remote computers over insecure networks, through the use of various cryptographic techniques.
Regardless of whether password shadowing is in effect on a given system, the passwd file is readable by all users so that various system utilities (e.g., grep) can work (e.g., to ensure that user names existing on the system can be found inside the file), while only the root user can write to it. Without password shadowing, this means that an ...
A binary string that labels a security principal (i.e., user or service program) - see access control and identity. For example, Kerberos uses names like user@REALM for users and service/hostname@REALM for programs. Credentials Information that proves an identity; used by an entity to act as the named principal.
Once a user has accepted another user's fingerprint, that fingerprint (or the key it refers to) will be stored locally along with a record of the other user's name or address, so that future communications with that user can be automatically authenticated. In systems such as X.509-based PKI, fingerprints are primarily used to authenticate root ...
SSH operates as a layered protocol suite comprising three principal hierarchical components: the transport layer provides server authentication, confidentiality, and integrity; the user authentication protocol validates the user to the server; and the connection protocol multiplexes the encrypted tunnel into multiple logical communication channels.

The OpenSSH server can authenticate users using the standard methods supported by the SSH protocol: with a password; public-key authentication, using per-user keys; host-based authentication, which is a secure version of rlogin 's host trust relationships using public keys; keyboard-interactive, a generic challenge–response mechanism, which ...
It is possible, however, to run it over SSH-1 (and some implementations support this) or other data streams. Running an SFTP server over SSH-1 is not platform-independent as SSH-1 does not support the concept of subsystems. An SFTP client willing to connect to an SSH-1 server needs to know the path to the SFTP server binary on the server side.
