Deployment Method:

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

1. Enter Your Internal Repository Url

(this should look similar to

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 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 checksum -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 checksum -y --source="'INTERNAL REPO URL'" 

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

Exit $exitCode

checksum - Command line file checksum validator.

Determine a checksum for a file

checksum checks a file and returns a checksum for md5, sha1, and sha2 (sha256 and sha512).

To use checksum you would simply provide a file path and it will return the sum for the file.


  • checksum -f="relative\path"
  • checksum "relative\path"
  • checksum -f="c:\absolute\path" -t=sha256

Validate a file against an existing signature

You can also check against an existing signature.
To validate against an existing signature (hash) you would simply provide the file and the expected signature. When checking a signature, if the signature is valid it exits with 0, otherwise it exits with a non-zero exit code.


  • checksum -f="c:\absolute\path" -c=8AC4EA9A7B18E67EA97088220C40041B355A2C3049AA4E290D1F65A94BEFA9EF
  • checksum -f="c:\absolute\path" -c=8AC4EA9A7B18E67EA97088220C40041B355A2C3049AA4E290D1F65A94BEFA9EF -t sha256


checksum [-t=sha1|sha256|sha512|md5] [-c=signature] [-f=]filepath


-?, --help, -h
Prints out the options.
-f, --file=VALUE
REQUIRED: file - The is the name of the file. The file should exist
-t, --type, --hashtype=VALUE
Optional: hashtype - 'md5', 'sha1', 'sha256', or 'sha512'. Defaults to 'md5' or is determined by length of passed check value.
-c, --check=VALUE
Optional: check - the signature you want to check. Not case sensitive.

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.
