2. Setup Your Environment

1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

2. Get the package into your environment

  • Open Source or Commercial:
    • Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to https://community.chocolatey.org/api/v2/. Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
    • You can also just download the package and push it to a repository Download

3. Copy Your Script

choco upgrade putty.install -y --source="'INTERNAL REPO URL'" [other options]

See options you can pass to upgrade.

See best practices for scripting.

Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:

choco upgrade putty.install -y --source="'INTERNAL REPO URL'" 

Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)
if ($validExitCodes -contains $exitCode) {
  Exit 0

  • Portable (*.portable/*.commandline (deprecated naming convention)/*.tool (deprecated naming convention)) - usually zips or archives that require no administrative access to install.
  • Install (*.install/*.app (deprecated naming convention)) - uses native installers, usually requires administrative access to install.

Package Approved

This package was approved as a trusted package on 22 May 2024.


PuTTY is a free implementation of Telnet and SSH for Windows and Unix platforms, along with an xterm terminal emulator.


  • Unicode support
  • Control over the SSH encryption key and protocol version
  • Command-line SCP and SFTP clients, called "pscp" and "psftp" respectively
  • Control over port forwarding with SSH (local, remote or dynamic port forwarding), including built-in handling of X11 forwarding
  • Emulates most xterm, VT102 control sequences, as well as much of ECMA-48 terminal emulation
  • IP Version 6 support
  • Supports 3DES, AES, Arcfour, Blowfish, DES
  • Public-key authentication support
  • Support for local serial port connections


  • PuTTY: the Telnet, rlogin, and SSH client itself, which can also connect to a serial port
  • PSCP: an SCP client, i.e. command-line secure file copy
  • PSFTP: an SFTP client, i.e. general file transfer sessions much like FTP
  • PuTTYtel: a Telnet-only client
  • Plink: a command-line interface to the PuTTY back ends
  • Pageant: an SSH authentication agent for PuTTY, PSCP and Plink
  • PuTTYgen: an RSA, DSA, ECDSA and EdDSA key generation utility
  • pterm: a standalone terminal emulator


  • If the package is out of date please check Version History for the latest submitted version. If you have a question, please ask it in Chocolatey Community Package Discussions or raise an issue on the Chocolatey Community Packages Repository if you have problems with the package. Disqus comments will generally not be responded to.
  • Support for putty 64bit have been added to the package when running chocolatey 0.10.4+, to keep using 32bit version of putty please pass --x86 when installing/upgrading putty.install (64bit installation may fail if 32bit is already installed)
  • Use of PuTTY, PSCP, PSFTP and Plink is illegal in countries where encryption is outlawed.
  • We believe it is legal to use PuTTY, PSCP, PSFTP and Plink in England and Wales and in many other countries, but we are not lawyers, and so if in doubt you should seek legal advice before downloading it.
  • You may find useful information at cryptolaw.org, which collects information on cryptography laws in many countries, but we can't vouch for its correctness.
