application which can act as a client for the SSH,
Telnet, rlogin, and raw TCP computing protocols. The name
"PuTTY" has no definitive meaning, 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.
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.
- Self-contained executable requires no installation.
