ZOC is a professional terminal emulation software for Windows and macOS. Its impressive list of emulations and powerful makes it a reliable and elegant tool that connects you to hosts and mainframes via,, serial cable and other methods of communication. With its modern user interface, this terminal has many ways of making your life easier. In its own way, ZOC is the Swiss Army Knife of terminal emulators: versatile, robust, proven.

Zssh (Zmodem SSH) is a program for interactively transferringfiles to/from a remote machine while using the secure shell (ssh).It is intended to be a convenient alternative to scp, avoidingthe need to re-authenticate each time a file is transferred.

ZMODEM is a file transfer protocol developed by Chuck Forsberg in 1986, in a project funded by Telenet in order to improve file transfers on their X.25 network. In addition to dramatically improved performance compared to older protocols, ZMODEM also offered restartable transfers, auto-start by the sender, an expanded 32-bit CRC, and control character quoting, allowing it to be used on.

ZOC as a Secure Shell Client: SSH is a communication protocol that encrypts and transports data over an unsecured network. Its main purpose is to establish an encrypted way of communication with a remote shell account. ZOC Terminal is the software, which runs on your local computer to connect to the remote server. Once connected, it lets you enter commands and see the output of those commands running on the remote computer. Overview of ZOC's SSH Features: • Based on industry reference implementation 7.3 • Client supports latest encryptions like ED25519 SHA256, SHA2 or AES-256ctr • SSH, keyboard interactive or password authentication • Dynamic (client as a SOCKS proxy) • (lets you run X-Windows applications from the remote session) • Static (tunneling of connections to remote destinations) • Proxy support (client connects to server through http/socks4/socks5) • SSH Agent and putty-agent between client and server • Client side SSH • SCP file transfer.

ZOC SSH Features in Detail ZOC is based on OpenSSH and supports the latest key exchange and encryption methods that the has to offer. Unlike OpenSSH, this ssh client is wrapped in a modern tabbed user interface with a powerful host directory, industrial strength emulations and scripting. Below is an overview and explanation of some core SSH features of ZOC Terminal.

Online sketching program. We also have a whitepaper offering a more. Key Exchange An especially difficult part of encrypted communication is the need to negotiate a shared secret (the key to use for encryption) over a public channel that could already be compromised.

The negotiation is performed through the so called Diffie-Hellman exchange or a variant thereof. ZOC supports all official diffie-hellman group exchanges, as well as the more modern ecdsa-sha2 and curve25519-sha256 protocols. Authentication Authenticating describes the process, where the user presents proof of who he is and the server deciding, if the user should be allowed access. The SSH protocol describes various methods that can be used for authentication. Of those, ZOC supports password authentication, pukey exchange and keyboard-interactive challenge. Public-key exchange comes in various flavors. ZOC understands RSA, DSA, ECDSA and ED25519 keys.
