Inf2Cat

Inf2Cat (Inf2Cat.exe) is a command-line tool that determines whether a driver package's INF file can be digitally-signed for a specified list of Windows versions. If so, Inf2Cat generates the unsigned catalog files that apply to the specified Windows versions.

    Inf2Cat /driver:
    PackagePath
     /os:
    WindowsVersionList [/nocat] [/verbose] [/?] [other switches]

The Inf2Cat tool is located in the Program Files\Windows Kits\8.0\bin\x86 or Program Files (x86)\Windows Kits\8.0\bin\x86 folder of the WDK.

Troubleshooting

If you see DriverVer set to a date in the future when building your driver, change your driver package project settings so that Inf2Cat sets /uselocaltime. To do so, use Configuration Properties->Inf2Cat->General->Use Local Time. Now both Stampinf and Inf2Cat use local time.

If you see An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B) Signability test failed., try one of these workarounds:

1. Set the project's inf2cat settings to /nocat and run inf2cat manually.
2. Delete inf2cat.exe.manifest from the \x86 folder of the active WDK to cause the tool to run in Visual Studio.

Switches and Arguments

/driver:PackagePath

Specifies the path to the directory that contains the INF files for driver packages. If the specified directory contains INF files for multiple driver packages, Inf2Cat will create catalog files for each driver package.

/nocat

Configures Inf2Cat to verify that the driver package complies with the signing requirements for the specified Windows versions, but not to generate a catalog files.

/os:WindowsVersionList

Configures Inf2Cat to verify that a driver package's INF file complies with the signing requirements for the Windows versions that are specified by WindowsVersionList. WindowsVersionList is a comma-separated list that includes one or more of the following version identifiers.

Inf2Cat ignores the case of the alphabetic characters of the version identifier strings. For example, 10_NI_X64 and 10_ni_X64 are both valid identifiers for Windows 11, version 22H2 x64 Edition.

/uselocaltime

Use local timezone while running driver timestamp verification tests. By default UTC is used.

/verbose

Configures Inf2Cat to display detailed information in a command window.

/?

Configures Inf2Cat to display help information in a command window.

/drm

Deprecated command line argument.
Add drm signature attribute in .inf file to add drm signature attribute.

/pe

Deprecated command line argument.
Add petrust signature attribute in .inf file to add petrust signature attribute.

/pageHashes

Include page hashes with files. Optionally followed by a list of files.

Comments

The Inf2Cat tool checks driver package's INF files for structural errors and verifies that a driver package can be digitally-signed. A driver package can be signed only if all of the files that are referenced in an INF file are present and the source files are in the correct location. If an INF file cannot be signed or if it contains structural errors, the driver package might not be installed correctly or might incorrectly display a driver signing warning dialog box during installation.

Inf2Cat generates a catalog file only if the catalog file is specified in the driver package's INF file and the catalog file applies to one or more of the specified Windows versions. If the INF Version section of an INF file supplies only a CatalogFile=filename.cat directive, that catalog file applies to the entire driver package. To support cross-platform installations, the INF file should include CatalogFile.PlatformExtension=unique-filename.cat directives.

For more information about signing a driver package, see Driver Signing.

To use Inf2Cat, you must be a member of the Administrators group on the system.

Examples

In the following example, c:\MyDriver contains a driver package whose INF file is MyInfFile.inf and the INF Version section in the INF file includes only the following CatalogFile directive:

[Version]
. . .
CatalogFile=MyCatalogFile.cat
. . .

For this example, the following Inf2Cat command would verify whether the driver package can be signed for Windows 10, version 21H2, 21H1, 20H2, 2004 x64 Edition and for Windows 11, version 21H2 x64 Edition. If the package can be signed for these versions, Inf2Cat would create the unsigned catalog file MyCatalogFile.cat.

Inf2Cat /driver:C:\MyDriver /os:10_VB_X64,10_CO_X64 

In the following example, c:\MyDriver contains a driver package whose INF file is MyInfFile.inf and the INF Version section in the INF file includes only the following two CatalogFile directives with platform extensions:

[Version]
. . .
CatalogFile.ntx86=MyCatalogFileX86.cat
CatalogFile.ntamd64=MyCatalogFileX64.cat
. . .

For this example, the following Inf2Cat command would verify whether the driver package can be signed for Windows 10, version 1809 x86 Edition and X64 Edition. In addition it checks if it can be signed by Windows Windows 10, version 1909, 1903 x86 Edition and X64 Edition. If the package can be signed for all of these versions, Inf2Cat will create the unsigned catalog files MyCatalogFileX86.cat and MyCatalogFileX64.cat.

Inf2Cat /driver:C:\MyDriver /os:10_RS5_X86,10_RS5_X64,10_19H1_X86,10_19H1_X64
