Definition of SSH | | | | | Secure Shell (SSH) secures connections over the network by encrypting passwords and other data. SSH is a program for logging into and executing commands on a remote machine, and it is intended to replace rlogin and rsh, and provide secure encrypted communications between two untrusted hosts over an insecure network.
As an authentication method, SSH supports RAS-based authentication. In this method, encryption and decryption are done using separate keys, and it is not possible to derive the decryption key from the encryption key. Each user creates a public/private key pair for authentication purposes. The server knows the public key, and only the user knows the private key. | | | |
