Creating a Catalog File for a Non-PnP Driver Package

You can use the MakeCat tool to create a catalog file for a non-PnP driver package.

Note  You must use the MakeCat tool only to create catalog files for driver packages that are not installed by using an INF file. If the driver package is installed by using an INF file, use the Inf2Cat tool to create the catalog file. Inf2Cat automatically includes all the files in the driver package that are referenced within the package's INF file. For more information about how to use the Inf2Cat tool, see Using Inf2Cat to Create a Catalog File.

To create a catalog file, you must first manually create a Catalog Definition File (..cdf) that describes the catalog header attributes and file entries. After this file is created, you can then run the MakeCat tool to create a catalog file

Creating a catalog file

To create a catalog file for a non-PnP driver package, follow these steps:

  1. Use a text editor to create a ..cdf file that lists the name of the catalog file to be created, its attributes, and the names of the files that are to be listed in the catalog file.

  2. Use the MakeCat command-line tool to create the catalog file. For more information about the MakeCat tool, see the Using MakeCat website.

  3. Install the catalog file on a computer on which the driver will be installed.

Overview of the MakeCat tool

The MakeCat tool does the following when it processes the ..cdf file:

  • Verifies the attributes of the catalog file that is defined by the ..cdf file, and adds the attributes to the catalog file.

  • Verifies the attributes for each file that is listed within the ..cdf file, and adds the attributes to the catalog file.

  • Generates a cryptographic hash, or thumbprint, of each of the listed files.

  • Stores each file's thumbprint in the catalog file.

Use the following MakeCat command to create a catalog file.


MakeCat -v CatalogDefinitionFileName..cdf

Where:

  • The -v option configures MakeCat to print execution and warning messages.

  • CatalogDefinitionFileName..cdf is the name of the catalog definition file.

Examples

The following example shows the contents of a typical catalog definition file that is named Good..cdf. The package to be cataloged contains two files, File1 and File2. The resulting catalog file is named Good.cat.


[CatalogHeader]
Name=Good.cat
PublicVersion=0x0000001
EncodingType=0x00010001
CATATTR1=0x10010001:OSAttr:2:6.0
[CatalogFiles]
<hash>File1=File1
<hash>File2=File2

The options that are used in this example are described below. For more information about these options, see the MakeCat website.

Name=Good.cat

Specifies the name of the catalog file (Good.cat).

PublicVersion=0x0000001

Specifies the version of the catalog file.

EncodingType=0x00010001

Specifies the message encoding type that is used to generate the thumbprint. The value 0x00010001 specifies a message encoding type of PKCS_7_ASN_ENCODING | X509_ASN_ENCODING.

CATATTR1=0x10010001:OSAttr:2:6.0

Specifies an attribute of the catalog file. To specify additional attributes, you must use separate CATATTR options, with each option assigned a unique numeric digit as a suffix. For example, use CATATT1 to specify one catalog file attribute and CATATT2 to specify another.

In this example, the attribute specified by using the CATATTR1 option has the following value:

0x10010001

Specifies the attribute to be the following:

  • 0x10000000 - Authenticated attribute (signed, included in the thumbprint).

  • 0x00010000 - Attribute is represented in plain text.

  • 0x00000001 - Attribute is a name-value pair.

OSAttr:2:6.0

The OSAttr attribute specifies the target Windows version whose signing requirements are compatible with the driver package. The attribute's value specifies the following:

  • The value 2 specifies the catalog file is compatible with NT-based versions of the Windows operating system.

  • The value 6.0 specifies the catalog file is compatible with Windows Vista.

    Note  If the driver package is compatible with multiple Windows versions, you must use separate CATATTR options to specify the OSAttr attribute for each Windows version.

<hash>File1=File1

Specifies a reference tag for the file File1 which is referenced through the catalog file. The value <hash>File1 results in the tag being the file's cryptographic hash, or thumbprint.

<hash>File1=File2

Specifies a reference tag for the file, File2, which is referenced through the catalog file. The value <hash>File2 results in the tag being the file's thumbprint.

The following example shows how to generate the catalog file, Good.cat, from a corresponding catalog definition file Good..cdf. Makecat saves Good.cat in the same folder where File1 and File2 are located.


MakeCat -v Good.cdf
