SSH products are available not only for Unix, but also for Windows, Macintosh, Amiga, OS/2, VMS, BeOS, PalmOS, Windows CE, and Java. Some programs are original, finished products, and others are ports of OpenSSH or of Tectia ancestors, undertaken by volunteers and in various stages of completion.
In the remaining chapters of this book, we cover several robust implementations of SSH for Windows and the Macintosh. But first, in this chapter, we quickly survey SSH products for many platforms.
We have set up a web page pointing to SSH-related products that we know. From this book's catalog page:

Every SSH implementation has a different set of features, but virtually all have one thing in common: a client program for logging into remote systems securely. Some clients are command line-based, and others operate like graphical terminal emulators, opening windows with dozens of configurable settings.
The remaining features vary widely across implementations. Secure file copy (scp and sftp), remote batch command execution, SSH servers, SSH agents, and particular authentication and encryption algorithms are found in only some of the products. Most include a generator of public and private keys.
