This article describe the steps to sign a cabinet (.cab) file.
- The Microsoft .NET Framework software development kit (SDK) 1.1 includes the Crypto API files that you must have to sign a .cab file. To download the SDK, visit the following Microsoft Web site:
- Use the following steps to sign and validate the .cab file:
- Type the following at a command prompt to create a private key file, Mycert.pvk. makecert -sv "mycert.pvk" -n "CN=My Company" mycert.cerThe file created in this step, Mycert.cer, is used to create an .spc file. Type the password in the dialog box.
- Create an .spc file from the certificate file with the correct password. To do so, type the following line at a command prompt: cert2spc mycert.cer mycert.spcNote that this step involves creation of a test private key. Alternatively, valid certificates can be created through Microsoft Certificate Server for Intranet use or purchased from external vendors for Internet use.
- Use the key information to sign the .cab file: signcode -v mycert.pvk -spc mycert.spc new.cab -t [Timestamp server URL]For more information about signtool, visit the following Microsoft Developer Network (MSDN) Web site:Note Specify the timestamp server URL at this step. The timestamp server URL provides a place to enter or edit the location of a timestamp server. A timestamp server validates the date and time that the cabinet file was signed. Certificate files can expire after a certain period of time. Contact your certificate file provider (certificate authority) for the location of their timestamp server.
Starting with Platform SDK February 2003, signcode.exe has been replaced with signtool.exe.
- Type the following at a command prompt to create a private key file, Mycert.pvk.
- Follow this procedure to validate a .cab file:
- Type the following at a command prompt to run Setreg.exe on the client system with the TRUE value so that the test certificates are recognized:setreg -q 1 TRUE
- Run Checktrust.exe to ensure that the CAB file is signing correctly:chktrust new.cab
- Type the following at a command prompt to run Setreg.exe on the client system with the TRUE value so that the test certificates are recognized:
