Signing Packages
Package signing is available with the purpose of ensuring the security and integrity of processes and libraries published from Studio.
NuGet offers two ways in which packages can be signed, either by an author or by a repository.
To enforce the use of signed packages, the
signatureValidationMode parameter in the Nuget.config file must be set to require. The file is located at %ProgramFiles%\UiPath\Studio. You can do this in one of two ways:
-
During installation, by installing from the command line with the option
ENFORCE_SIGNED_EXECUTION=1.For example, the following command installs Studio, a Robot as a Windows service, the local activities packages, and enforces the usage of signed packaged in your UiPath environment:UiPathStudio.msi ADDLOCAL=DesktopFeature,Studio,Robot,RegisterService,Packages ENFORCE_SIGNED_EXECUTION=1. -
After installation, by manually editing the
Nuget.configfile.If you set the parameter after installation, the changes take effect after you:
- Restart the Robot Service.
- Remove all existing .NuGet packages from
%ProgramFiles%\UiPath\Studio\Packagesand%userprofile%\.nuget\packages. - Restart Studio/Assistant.
By default, UiPath packages are repository and author-signed. This means that such packages can be downloaded and installed using Manage Packages without having to perform any additional actions. For information on how to add additional trusted authors, repositories, and/or owners, see following sections on this page.
Important: When multiple feeds are used, NuGet chooses the feed that responds the fastest. If one of the feeds does not include signed
packages and dependencies, the Robot might receive a package or dependency that is not signed, causing the automation to fail.
In order to avoid this, make sure that all configured feeds have packages and dependencies signed.
To download, install, and run packages signed with a certain certificate, add the certificate
as a trusted source. To do so, modify the
nuget.config file in the
installation folder, mainly the section <trustedSigners>.
To add a trusted author, you need to open the
NuGet.config file located at
%ProgramFiles%\UiPath\Studio\NuGet.config. Then, provide the
certificatefingerprint and hashAlgorithm. Check this
page to get more information
about the certificate fingerprint.
Set the
allowUntrustedRoot to true or
false:
allowUntrustedRoot = "true"- trusted signer should be allowed to chain to an untrusted root.allowUntrustedRoot = "false"- trusted signer should not be allowed to chain to an untrusted root.
The entry should be similar to the example below:
<trustedSigners>
<author name="UiPath">
<certificate fingerprint="1234512345123451234512345123123123123123123123123123112312312E5" hashAlgorithm="SHA256" allowUntrustedRoot="true"/>
</author>
</trustedSigners><trustedSigners>
<author name="UiPath">
<certificate fingerprint="1234512345123451234512345123123123123123123123123123112312312E5" hashAlgorithm="SHA256" allowUntrustedRoot="true"/>
</author>
</trustedSigners>For more information on adding UiPath as a trusted signer, see Package Signature Verification in the Robot guide.
Adding a trusted repository is done roughly the same as adding an author, with the
difference that the
serviceIndex must also be added.
Below is an example of a trusted repository added to the
NuGet.config
file:
<trustedSigners>
<repository name="UiPath Repository" serviceIndex="https://uipath.repository">
<certificate fingerprint="1234512345123451234512345123123123123123123123123123112312312E5" hashAlgorithm="SHA256" allowUntrustedRoot="true" />
</repository>
</trustedSigners><trustedSigners>
<repository name="UiPath Repository" serviceIndex="https://uipath.repository">
<certificate fingerprint="1234512345123451234512345123123123123123123123123123112312312E5" hashAlgorithm="SHA256" allowUntrustedRoot="true" />
</repository>
</trustedSigners>A repository may have multiple author-signed packages. In this case, the
<owners> tag can be used for allowing only packages signed by
trusted authors to be installed.
Add the trusted authors between the
<owners> tags, as in the example
below:
<trustedSigners>
<repository name="UiPath Repository" serviceIndex="https://uipath.repository">
<certificate fingerprint="1234512345123451234512345123123123123123123123123123112312312E5" hashAlgorithm="SHA256" allowUntrustedRoot="true" />
<owners>Author1;Author2</owners>
</repository>
</trustedSigners><trustedSigners>
<repository name="UiPath Repository" serviceIndex="https://uipath.repository">
<certificate fingerprint="1234512345123451234512345123123123123123123123123123112312312E5" hashAlgorithm="SHA256" allowUntrustedRoot="true" />
<owners>Author1;Author2</owners>
</repository>
</trustedSigners>-
In the Certificate signing tab, add the certificate path on your local
machine. Use the
button to navigate to the path if
needed. Only .pfx and .p12 certificate file formats are accepted.
Timestamps are a secure way of keeping track of the date and time when a package was signed. To learn more about timestamping in the context of NuGet package signing, check out this link.
If the certificate timestamper is invalid, an error message containing the project name is thrown in Studio after clicking the Publish button. A similar error message is also logged in the Output panel.
Note: If signature verification is NOT enforced, processes created with Studio prior to v2019.4 are still executed, regardless
if they are signed or not.
Use the Mass Update Command Line tool to sign multiple packages and then publish them to a location.
Note: Having an unsigned dependency in the project may prevent other dependencies from being resolved when using the Repair Dependency feature. Remove the unsigned package from the project to resolve signed dependencies.
