If necessary, the catalog files are renamed to prevent name conflicts with existing catalog files. Specifies that a unique name is automatically generated for the added catalog files. If this option isn't specified, SignTool adds the specified catalog to the catalog database. Removes the specified catalog from the catalog database.

Specifies that the catalog database identified by the GUID is updated. If you don't use either /d or /g, SignTool updates the system component and driver database. Specifies that the default catalog database is updated. The following table lists the options that can be used with the catdb command.

Global optionĭisplays no output if the command runs successfully, and displays minimal output if the command fails.ĭisplays verbose output regardless of whether the command runs successfully or fails, and displays warning messages. The following options apply to all SignTool commands. For a list of the options supported by the verify command, see verify command options. Determines whether the signing certificate was issued by a trusted authority, whether the signing certificate has been revoked, and, optionally, whether the signing certificate is valid for a specific policy. For a list of the options supported by the timestamp command, see timestamp command options. For a list of the options supported by the sign command, see sign command options. Digital signatures protect files from tampering and enable users to verify the signer based on a signing certificate. For a list of the options supported by the catdb command, see catdb command options.ĭigitally signs files. Catalog databases are used for automatic lookup of catalog files and are identified by GUID. SignTool supports the following commands: CommandĪdds a catalog file to, or removes it from, a catalog database. In addition to the global /q and /v options, each command supports a unique set of options. For a description of each command, see the next table.Īn option that modifies a command.

One of four commands that specifies an operation to perform on a file: catdb, sign, timestamp, or verify. It is considered to be more secure than SHA1 by the industry. In later versions of SignTool, the warning becomes an error. If /fd isn't specified during signing and if /td isn't specified during time stamping, the command throws a warning, error code 0, initially. The SignTool sign command requires the file digest algorithm option ( /fd) and the time stamp digest algorithm option ( /td) during signing and time stamping, respectively. The Windows 10 SDK, Windows 10 HLK, Windows 10 WDK, and Windows 10 ADK builds 20236 and later require that you specify the digest algorithm.
