PuTTY (/ˈpʌti/[2]) is a free and open-source terminal emulator, serial console and network file transfer application. It supports several network protocols, including SCP, SSH, Telnet, rlogin, and raw socket connection. It can also connect to a serial port (since version 0.59). The name "PuTTY" has no definitive meaning,[3] 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[4][5] and Windows Mobile.
PuTTY was written and is maintained primarily by Simon Tatham and is currently beta software.
Features
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 (no certificate support)
- Support for local serial port connections
- Self-contained executable requires no installation
- Supports the zlib@openssh.com delayed compression scheme (as of r9120 2011-03-05)

History
PuTTY's development dates back to late 1998,[1] and it has been a usable SSH-2 client since October 2000.[6][7]
Components
PuTTY consists of several components:
- PuTTY: the Telnet, rlogin, and SSH client itself, which can also connect to a serial port (since version 0.59)
- 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

[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.
