Unsign

Unsign is a specialized software tool designed to completely remove digital signatures from a wide range of executable files, including .exe, .dll, .sys, and .drv formats. This process is essential for developers and security professionals who need to modify, analyze, or re-sign these files. By thoroughly cleaning the signature data, Unsign ensures that the files are ready for new certificates, eliminating common errors that occur during the re-signing process. It is an indispensable utility for software repackaging, testing, and security research workflows.
