SSH is the name of :
- a secure communication protocole (normalized by the IETF)
- a set of tools using ... the SSH protocole
I know, it's not cool one name for two things ....
The goals of SSH are two :
- strong autentication (by public key autentication)
- strong encryption of communications (AES, Blowfish 3DES etc ...)
You can do a lot of things :
- replace telnet, rcp, rlogin, rsh by ssh (PuTTy est the best client =
on Windows environment, OpenSSH on Unices). The communications are =
encrypte. So noone can use a sniffer to capture your username and =
password during a session starting.
- Tunneling non secure protocols like pop, smtp, snmp etc ....
- create a SSO-like system using a ssh agent (Sigle Sign On =3D ONE =
autentication --> lots of communications (without autentication =
anymore)).
