What is signtool.exe for?

I have a feeling it's the equvilent of signing jars in Java, but I'm not开发者_开发问答 entirely sure if that's what it is for.

From MSDN:

Sign Tool is a command-line tool that digitally signs files, verifies signatures in files, and time-stamps files.

Sign Tool is automatically installed with Visual Studio. To start the tool, use the Visual Studio Command Prompt. Sign Tool has the following general syntax:

signtool [command] [options] [file_name | ...]

Regarding the sign command:

Digitally signs files. Digital signatures protect files from tampering, and enable users to verify the signer based on a signing certificate.

It signs files with digital signatures, so I guess you can compare it with signing jars. Here's what MS says about it.
