NOTE: This applies to both open source and commercial editions of Chocolatey.

1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

  • 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 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. Enter your internal repository url

(this should look similar to

4. Choose your deployment method:

choco upgrade psiphon -y --source="'STEP 3 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 psiphon -y --source="'STEP 3 URL'"

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

Exit $exitCode

Psiphon Circumvention System is an open source relay-based Internet censorship circumventer.

The system consists of a client application, which configures a users computer to direct Internet traffic; and a set of servers, which proxy client traffic to the Internet. As long as a client can connect to a Psiphon server, it can access Internet services that may be blocked to the user via direct connection.

Design goals

  • The Internet is not World Wide if someone somewhere is denied access.
  • The right to freedom of opinion and expression affects us all, even if censorship does not.

Security note

To accomplish its design goals, Psiphon uses computer security technology including encryption and digital signatures. Using these algorithms does not mean Psiphon 3 offers additional security properties such as privacy or authentication of destination sites for users' Internet traffic. [ref]

For additional information about how Psiphon works, please see the FAQ.

Cloud service client

Psiphon is a program that uses various tunnelling technologies to securely connect to a cloud service. Please be aware that this program is anti-censorship and does not guarantee privacy. To determine what information is collected by your usage of the service and how it may be used, please see the privacy policy.

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).

Chocolatey Pro provides runtime protection from possible malware.
