About putty-ssh.org

What This Site Is

putty-ssh.org is a community reference site providing practical guides, tutorials, and documentation for PuTTY and its companion tools — PuTTYgen, Pageant, Plink, PSCP, and PSFTP. The site covers everything from downloading and verifying PuTTY on Windows to generating SSH key pairs, automating remote commands with Plink, transferring files with PSCP, and hardening SSH connections against common threats.

Why We Built It

PuTTY has been a cornerstone of Windows SSH access since 1999. Despite that, practical documentation scattered across forums and mailing lists makes it harder than it should be for new administrators to get started quickly or diagnose configuration problems.

This site consolidates step-by-step instructions, configuration reference tables, and security guidance into one place — structured for readers who want answers fast rather than having to piece together information from multiple sources.

What We Cover

• Downloading and verifying PuTTY from official sources
• PuTTYgen — generating RSA, Ed25519, and ECDSA key pairs
• Pageant — managing an SSH authentication agent on Windows
• Plink — non-interactive SSH for scripts and automation
• PSCP — secure file copy from the command line
• Session configuration, tunnels, keepalives, and colour schemes
• Detecting and avoiding trojanized PuTTY installers
• SSH key authentication vs password-based login

Relationship to the PuTTY Project

PuTTY is free, open-source software written by Simon Tatham and contributors and distributed under the MIT licence. This site is a community documentation resource with no commercial or organisational relationship to the PuTTY development team. The official PuTTY project is hosted at chiark.greenend.org.uk and putty.software — always download PuTTY from those sources directly.
