PuTTY

PuTTY, a popular terminal emulator, is an open-source, light-weight, and free SSH client. It was developed by Simon Tatham in C language. Its primary function is to connect to a computer remotely while offering the facilities of transferring files, manipulating data, etc.

It offers support to a variety of network protocols like SSH, Telnet, Serial, SCP, SFTP, etc. PuTTY also comes with a command-line tool called “psftp” which can securely transfer files between computers over an SSH connection. It is compatible to use in most of the operating systems (for both 32 bit and 64 bit).

PuTTY includes PuTTYgen, a key generator tool for creating pairs of public and private SSH keys. For help with PuTTY SSH, visit the PuTTY SSH FAQ page.

Mac users: The functionality of PuTTY and PuTTYgen is incorporated into macOS. Open Terminal to get started.
