If H(pwd) produces the password the server has stored, then the authentication is successful. The server will then store pwd as the current reference. For subsequent authentications, the user will provide password i. (The last password on the printed list, password n, is the first password generated by the server, H(W), where W is
In 1995, Tatu Ylönen, a researcher at Helsinki University of Technology in Finland designed the first version of the protocol (now called SSH-1) prompted by a password-sniffing attack at his university network. [13]
Secure Shell (SSH) is a protocol allowing secure remote login to a computer on a network using public-key cryptography.SSH client programs (such as ssh from OpenSSH) typically run for the duration of a remote login session and are configured to look for the user's private key in a file in the user's home directory (e.g., .ssh/id_rsa).
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. The ssh-keygen utility is used to generate, manage, and convert ...
Featuring Secure Remote Password protocol (SRP) as specified in secsh-srp [7] [8] besides, public-key authentication. Kerberos is somewhat supported as well. [citation needed] Currently however for password verification only, not as a single sign-on (SSO) method. [citation needed] lsh was started from scratch and predates OpenSSH. [9]

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 ...
The SCP is a network protocol, based on the BSD RCP protocol, [5] which supports file transfers between hosts on a network. SCP uses Secure Shell (SSH) for data transfer and uses the same mechanisms for authentication, thereby ensuring the authenticity and confidentiality of the data in transit.
