PuTTY

Description

PuTTY is a free SSH and Telnet client suite for Windows and Unix platforms. It includes the PuTTY terminal client along with companion tools for secure copy, SFTP sessions, command-line connections, SSH authentication, and key generation.

The official project describes PuTTY as an implementation of SSH and Telnet with an xterm terminal emulator, maintained primarily by Simon Tatham. It remains widely used because it is lightweight, portable, scriptable through companion utilities, and familiar to administrators who manage remote systems.

This FossHub page records PuTTY 0.84 as a reviewed release entry and links users to the official project release page. The package row keeps the version, filename, size, and release metadata from the release inventory without adding a direct binary download.

PuTTY Features

PuTTY's main role is remote terminal access, but the suite is broader than the main putty.exe client. The official release page includes PSCP for secure copy, PSFTP for file-transfer sessions, Plink for command-line use of PuTTY back ends, Pageant as an SSH authentication agent, and PuTTYgen for key generation.

The project also publishes installer packages, standalone executables, source archives, documentation, signatures, and checksum files. That matters for administrators who need to verify releases, keep a portable toolkit, or install only the utilities required for a specific support workflow.

• SSH and Telnet terminal client for Windows and Unix platforms.
• PSCP and PSFTP utilities for secure copy and SFTP file-transfer workflows.
• Plink command-line interface for scripted or terminal-based connections.
• Pageant SSH authentication agent and PuTTYgen key-generation utility.
• Official documentation, source archives, signatures, and checksum files for release verification.

Release and License Notes

PuTTY is listed here as open source under MIT terms. The current FossHub record is based on the official PuTTY 0.84 release dated May 22, 2026, and the release inventory metadata has been preserved.

FossHub is not the maintainer of PuTTY and does not redistribute the installer from this page. The official project page should be used for the current stable release, development snapshot distinction, checksum files, signatures, legal notices about encryption, and release-specific security notes.

PuTTY Review

PuTTY remains useful because it is focused and predictable. It is a good fit for administrators, developers, network engineers, and support teams who need quick SSH or Telnet access without installing a large terminal environment.

The companion utilities are a major part of the value. PSCP, PSFTP, Plink, Pageant, and PuTTYgen cover common remote-access tasks that often sit around an SSH client, which makes PuTTY practical as a small toolkit rather than a single terminal window.

For modern environments, PuTTY should be evaluated alongside key-management policy, supported algorithms, release notes, and operating-system deployment requirements. Keeping current matters because recent PuTTY releases have included security fixes as well as protocol and usability improvements.
