 PuTTY 0.53b main configuration dialog on Windows 2000 PuTTY is an SSH, Telnet, rlogin, and raw TCP client. It was originally available only for Windows, but is now also available on various Unix platforms (as well as several other platforms as unofficial ports). It is written and maintained primarily by Simon Tatham, and is open source, licensed under the MIT license.
Recently (as of October 2004) 2 consecutive versions (0.54 and 0.55) have been found to have significant security holes, allowing client compromise even before the server is authenticated. If you use PuTTY and haven't checked the site for updates recently you are strongly encouraged to check your version.
Some features of PuTTY are:
- The storing of hosts and preferences for them for later use.
- Control over the SSH encryption key and protocol version.

There is no definite meaning of what PuTTY stands for but to reference the FAQ on the PuTTY home page this is what it says:
(PuTTY is )"...the name of a popular SSH and Telnet client. Any other meaning is in the eye of the beholder. It's been rumoured that PuTTY is the antonym of getty, or that it's the stuff that makes your Windows useful, or that it's a kind of plutonium Teletype. We couldn't possibly comment on such allegations."
