Modify package publisher script

  • Article

The Modify package publisher script in the MSIX Toolkit can be used to update the publisher in the manifest before re-signing the package based on a new certificate. This script is currently limited to MSIX apps, and not MSIX bundles.

Syntax

.\modify-package-publisher.ps1 -directory <String> -redist <String> -certPath <String> [[-pfxPath] <String>] [[-Password] <String>] [[-forceContinue]<Switch>]

Examples

Update the publisher based on the certificate

PS C:\> .\modify-package-publisher.ps1 -directory "C:\MSIX" -redist "C:\MSIX-Toolkit\Redist" -certPath "C:\cert\mycert.cer"

This command recursively searches the contents of C:\MSIX for all MSIX packages and updates the MSIX app publisher to match the publisher of the certificate located at C:\cert\mycert.cer. Signing an MSIX package format application with a SHA1 certificate is unsupported.

Update the publisher and sign the MSIX app

PS C:\> .\modify-package-publisher.ps1 -directory "C:\MSIX" -redist "C:\MSIX-Toolkit\Redist" -certPath "C:\cert\mycert.cer" -pfxPath "C:\cert\CertKey.pfx"

This command recursively searches the contents of C:\MSIX for all MSIX packages and updates the MSIX app publisher to match the publisher of the certificate located at C:\cert\mycert.cer. Then, the command re-signs the identified MSIX packages using the certificate located at C:\cert\CertKey.pfx. Signing the MSIX package format application with a SHA1 certificate is unsupported.

Update the publisher and sign the MSIX app with a password-protected PFX certificate

PS C:\> .\modify-package-publisher.ps1 -directory "C:\MSIX" -redist "C:\MSIX-Toolkit\Redist" -certPath "C:\cert\mycert.cer" -pfxPath "C:\cert\CertKey.pfx" -password "aaabbbccc"

This command recursively searches the contents of C:\MSIX for all MSIX packages and updates the MSIX app publisher to match the publisher of the certificate located at C:\cert\mycert.cer. Then, the command re-signs the identified MSIX packages using the certificate located at C:\cert\CertKey.pfx using the password aaabbbccc to unlock the password protected certificate. Signing the MSIX package format application with a SHA1 certificate is unsupported.

Update the publisher, sign the MSIX app, and force continue to next MSIX app

PS C:\> .\modify-package-publisher.ps1 -directory "C:\MSIX" -redist "C:\MSIX-Toolkit\Redist" -certPath "C:\cert\mycert.cer" -pfxPath "C:\cert\CertKey.pfx" -forceContinue -pfxPath "C:\cert\CertKey.pfx"

This command recursively searches the contents of C:\MSIX for all MSIX packages and updates the MSIX app publisher to match the publisher of the certificate located at C:\cert\mycert.cer. Then, the command re-signs the identified MSIX packages using the certificate located at C:\cert\CertKey.pfx. If any errors occur while processing an MSIX package, the script will continue to update the publisher and re-sign the identified MSIX packages. Signing the MSIX package format application with a SHA1 certificate is unsupported.
