Appx/MSIX Signing (SignTool)
Appx and MSIX are Windows application packaging formats whose manifest publisher identity must be signed with a matching certificate, typically using Microsoft’s Signtool utility.
Use Cases
Sign Windows app packages so the OS trusts the declared publisher identity.
Manifest-Aligned Signing
Aligns the package manifest’s publisher identity with the signing certificate before signing with Signtool.
Repeatable Workflow
Unpacks, aligns, and repacks packages as part of a repeatable signing process.
HSM-Backed Keys
Keeps private keys in the HSM without changing existing packaging processes.
