PuTTY is a terminal emulator application which can act as a client for the SSH, Telnet, rlogin, and raw TCP computing protocols. The name "PuTTY" has no definitive meaning [ cite web | quote = [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. | url = http://www.chiark.greenend.org.uk/~sgtatham/putty/faq.html#faq-meaning | title = PuTTY FAQ ] , though 'tty' is the name for a terminal in the Unix tradition, usually held to be short for teletype.

PuTTY was originally written for Microsoft Windows, but it has been ported to various other operating systems. Official ports are available for some Unix-like platforms, with work-in-progress ports to Classic Mac OS and Mac OS X, and unofficial ports have been contributed to platforms such as Symbian and Windows Mobile.

PuTTY was written and is maintained primarily by Simon Tatham and is currently beta software. Licensed under the MIT License, PuTTY is free and open source software.


Some features of PuTTY are:
* The storing of hosts and preferences for later use.
* Control over the SSH encryption key and protocol version.
* Command-line SCP and SFTP clients, called "pscp" and "psftp" respectively.
* Control over port forwarding with SSH (local, remote or dynamic port forwarding), including built-in handling of X11 forwarding.
* Emulates most xterm, VT102 control sequences, as well as much of ECMA-48 terminal emulation.
* IPv6 support.
* Supports 3DES, AES, Arcfour, Blowfish, DES.
* Public-key authentication support.
* Support for local serial port connections.

Version history

Prior to 0.58, three consecutive releases (0.55–0.57) were made to fix significant security holes in previous versions, some allowing client compromise even before the server is authenticated.

Version 0.58, released in April 2005, contained several new features, including improved Unicode support, for international characters and right-to-left or bidirectional languages.

Version 0.59, released in January 2007, implemented new features such as connection to serial ports, local proxying, sports SSH and SFTP speed improvements, changes the documentation format (for Vista compatibility) and has several bugfixes.

The 0.60 version implements three new features and some bugfixes.


Main functions are realized by PuTTY files themselves:

* PuTTY - the Telnet and SSH client itself;
* PSCP - an SCP client, i.e. command-line secure file copy;
* PSFTP - an SFTP client, i.e. general file transfer sessions much like FTP;
* PuTTYtel - a Telnet-only client;
* Plink - a command-line interface to the PuTTY back ends;
* Pageant - an SSH authentication agent for PuTTY, PSCP and Plink;
* PuTTYgen - an RSA and DSA key generation utility;
* pterm - a standalone terminal emulator.
