ZOC Terminal is a professional ssh client and terminal emulator. With its modern user interface, it has many ways of making your life easier.
In its own way, ZOC is the Swiss Army Knife of terminal emulators:
versatile, robust, proven.
Technical SSH BasicsThe SSH protocol is described in RFC 4253. The document defines a protocol that provides encryption, cryptographic host authentication, and data integrity.

SSH Client Features and RequirementsIn other words, there are many benefits to using a SSH client. The SSH protocol offers safe authtication, encryption and verification that you are connected to the correct computer. Since most part of the communication path runs over networks that are in control of somebody else (the internet providers, etc.), they could potentially reroute the traffic to another computer. This computer could then play the role of the server which you actually wanted to connect to (man-in-the-middle attack). A SSH feature called known_hosts can prevent this. SSH-clients should also provide a variety of authentication methods. These include public/private key, username/password and custom formats. The latter can include a systems where the user provides information that only the authorized users know, e.g. by using a SecurID card or by entering an access code from his mobile phone. To connect to a variety of different servers, the ssh-client software it has to support latest encryption protocols and key exchange mthods. Many servers over time switch to better encryption methods, so the ssh clients need to support these as well, because encryption methods that seemed secure a few years ago, are no longer unbreakable today. Other typical must have features for a ssh client would be:

To use SSH, You Also Need a Good Terminal EmulatorHowever, the SSH protocol only defines the connection and transmission of data between the client and server. But the purpose of the client side software usually is terminal emulation, a software is required that lets the user control a remote computer by sending keyboard input to, and receive formatted text (color, cursor placement, etc.) from the server (displaying it on the user's computer). Therefore the user's software at least needs to be able to perform these functions (i.e. those of a terminal emulator: supporting various terminal emulations, file transfer, printing), but it should also offer convenience functions like host directory, script-automation, logging and so on. ZOC Terminal offers all those features and a lot more. With secure-shell features like latest encryption and public key authentication, tunneling, port forwarding, smart card auth, etc. this makes ZOC an SSH client that you should try.
