SignetSure - Create digital signatures. Authenticate files with single API call.

Consider the following two scenarios.

Scenario One:

You push-publish programs and data over the Internet. Disaster would strike if hackers could impersonate you and send their own files to your subscribers. You have installed a program on the subscriber's machine that receives your files. This program must be able to authenticate files even against a hacker who has reverse-engineered your program.

Scenario Two:

You distribute registered software with a datafile that identifies the registered user (e.g. user name, product serial number, et cetera). It is important that users not be able to modify their own registration information, even if someone reverse-engineers your program.

SignetSure solves the problems of both these scenarios.
