An Embedded SSH Client/Server
RomSShell is an optional Secure Shell (SSH) toolkit that is often used in conjunction with RomCLI to deliver secure remote device management capabilities. SSH provides encrypted communications between hosts over an insecure network. SSH and RomSShell offer a range of client authentication options other than X.509 public-key certificates which require a fully functioning public key infrastructure. SSH is also useful for port forwarding (sometimes called SSH tunneling) allowing you to arbitrarily tunnel secure TCP connections.
Although traditionally found in enterprise and networking infrastructure products, SSH popularity has spread to many additional vertical markets and now includes: consumer electronics, defense, gaming devices, medical applications, and the Smart Grid.
Allegro’s RomSShell client/server toolkit supports SSH version 2 and is specifically written for use in resource constrained embedded systems environments.
