It can handle large bursts of text quickly, support very large scrollback buffers, and it closely matches xterm's behavior. Hterm stands out from many existing web terminals in that it was built from the start to match the performance and correctness of “native” terminals such as xterm and Terminal.app. How do hterm and Secure Shell differ from existing web terminals? You can safely have any of them installed simultaneously. That is why we have a “Secure Shell App” and a “Secure Shell Extension” in the store (as well as “dev” versions of each). Icon shows up in the chrome://apps list (vs in the extension bar).Here are the few features available in the App: If you do not care about the Chrome OS specific features, then the two versions are equivalent.
The only option we’re left with is to maintain both an extension and an app at the same time. Unfortunately, doing so means we‘d lose access to some APIs that we use on Chrome OS specifically. In order to work on non-Chrome OS platforms, we need to migrate it to an extension. That means the Secure Shell App would only be available on Chrome OS. Secure Shell was built on that technology.įast forward a few years and Chrome Apps were deprecated on all non-Chrome OS platforms. What's the difference between the Secure Shell App and Extension?Ĭhrome Apps were launched to create applications using web technology that would work like native apps on any platform Chrome runs on. The crosh shell will use the newer terminal emulator from Secure Shell when possible. TL DR - Don't use crosh for ssh any more, use the Secure Shell app instead. See chromeos-crosh.md in this directory for the details. How do Secure Shell and hterm relate to the “crosh” (Ctrl+Alt+T) command in Chrome OS? It does not provide SSH access (or any other text-based command) on its own. It is intended to be fast enough and correct enough to compete with native terminals such as xterm, gnome-terminal, konsole and Terminal.app. “HTML Terminal”, or hterm, is an xterm-compatible terminal emulator written entirely in JavaScript.

Secure Shell provides similar functionality to PuTTY on Microsoft Windows(c) systems, and the ssh command-line application on Mac OS X and Linux systems. Secure Shell is a Chrome Application that combines the “ssh” command (see for details) ported to NativeClient with the “hterm” terminal emulator to provide a secure shell client for the Chrome browser.
