Packaging and signing databases
If you want to convey to users of a database executable file that they can trust the file,
use the Package And Sign tool to create an Access Deployment (.accdc) file. An .accdc
file contains one database that has been compressed. The file is signed by using a
digital signature, signifying that no changes have been made since the package was
created.
TIP
You can purchase a digital signature from a third-party company. For information,
search for
digital signature
in Access Help.
