general file transfer sessions much like FTP PuTTYtel a Telnet-only client Plink a command-line interface to the PuTTY back ends. Can also use SFTP to perform transfers PSFTP an SFTP client, i.e. PuTTY the Telnet, rlogin, and SSH client itself, which can also connect to a serial port PSCP an SCP client, i.e. PuTTY development began late in 1998, and was a usable SSH-2 client by October 2000. PuTTY does not support session tabs directly, but many wrappers are available that do. PuTTY comes bundled with command-line SCP and SFTP clients, called 'pscp' and 'psftp' respectively, and plink, a command-line connection tool, used for non-interactive sessions. It can also be used with local serial port connections. The network communication layer supports IPv6, and the SSH protocol supports the delayed compression scheme. It also can emulate control sequences from xterm, VT220, VT102 or ECMA-48 terminal emulation, and allows local, remote, or dynamic port forwarding with SSH (including X11 forwarding). PuTTY supports SSO through GSSAPI, including user provided GSSAPI DLLs. PuTTY uses its own format of key files – PPK (protected by Message Authentication Code). 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 AES, 3DES, RC4, Blowfish, DES, and Public-key authentication. PuTTY was written and is maintained primarily by Simon Tatham, a British programmer. Official ports are available for some Unix-like platforms, with work-in-progress ports to Classic Mac OS and macOS, and unofficial ports have been contributed to platforms such as Symbian, Windows Mobile and Windows Phone. PuTTY was originally written for Microsoft Windows, but it has been ported to various other operating systems. The name 'PuTTY' has no official meaning.

It supports several network protocols, including SCP, SSH, Telnet, rlogin, and raw socket connection. PuTTY ( / ˈ p ʌ t i/) is a free and open-source terminal emulator, serial console and network file transfer application.
