I've got a file, which is digitally signed, but I would like to know how (the method/format/...)A binwalk on the file reveals a JFFS2 archive (after an offset of 64 bytes... that's maybe something ?), which I can extract, edit and browse ; but nothing about any signature.Have you any experience with this kind of stuff ? Could the first 64 bytes be a signature ? What kind of format ? Is there any tools (openssl ?) alowing to detect a signature (in any possible format) in a file ?
