PuTTY supports many variations on the secure remote terminal, and provides user control over the [[Secure shell|SSH]] encryption key and protocol version, alternate ciphers such as [[Triple DES|3DES]], [[RC4|Arcfour]], [[Blowfish (cipher)|Blowfish]], and [[Data Encryption Standard|DES]], and [[Public-key]] authentication. It also can emulate control sequences from [[xterm]], [[VT102]] or [[ECMA-48]] [[terminal emulator|terminal emulation]], and allows local, remote, or dynamic [[port forwarding]] with SSH (including [[X11]] forwarding). The network communication layer supports [[IPv6]], and the SSH protocol supports the zlib@openssh.com delayed compression scheme. It can also be used with local serial port connections.

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

PuTTY supports many variations on the secure remote terminal, and provides user control over the SSH encryption key and protocol version, alternate ciphers such as 3DES, Arcfour, Blowfish, and DES, and Public-key authentication. It also can emulate control sequences from xterm, VT102 or ECMA-48 terminal emulation, and allows local, remote, or dynamic port forwarding with SSH (including X11 forwarding). The network communication layer supports IPv6, and the SSH protocol supports the zlib@openssh.com delayed compression scheme. It can also be used with local serial port connections.

PuTTY comes bundled with command-line SCP and SFTP clients, called "pscp" and "psftp" respectively.

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

  3. ^ "PuTTY FAQ". [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.
