PuTTY is a free implementation of SSH and Telnet for Windows and Unix platforms, along with an xterm terminal emulator.
PuTTY 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. The name “PuTTY” has no official meaning.[5]
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 macOS, and unofficial ports have been contributed to platforms such as Symbian,[6][7] Windows Mobile and Windows Phone.
PuTTY was written and is maintained primarily by Simon Tatham, a British programmer.
Latest news
These features are new in 0.85 (released 2026-08-16):
Security issue: fixed a remotely triggerable use-after-free in Pageant. (Might be exploitable to execute code, although this is not proved.)
Security issue: fixed a remotely triggerable buffer overflow if the OpenSSH encrypt-then-MAC cipher modes are in use. (However they are only used if a server supports nothing else.)
Security issue: fixed a buffer overflow in private key decryption, if the private key is constructed maliciously. (Only triggerable on purpose if you let somebody else generate your key for you.)
Denial-of-service security fixes: a server can trigger a tight loop in PuTTY, and even a MITM can make it consume unlimited memory at startup.

Better client is Bitvise SSH Client, in case you did not know. Give it a look.
