SignetSure is a Win32 security software that digitally signs files to protect them from unauthorized alteration. With a single API call, files can be authenticated using RSA public key cryptography. Available for use with C/C++ or Visual Basic.

There are two scenarios where SignetSure is particularly useful. The first scenario is when you push-publish programs and data over the internet. If hackers impersonate you and send their files to your subscribers, it would be a nightmare. However, if you have installed SignetSure on the subscriber's machine, it would be able to authenticate files even against a hacker who has reverse-engineered your program.
In the second scenario, you distribute registered software with a data file that identifies the registered user, including the user name, product serial number, and more. It is essential that users can’t modify their own registration information, even if someone reverse-engineers your program.
SignetSure offers an outstanding solution to both these scenarios. It uses RSA public key cryptography to create an encryption key and sign your file using a simple GUI application. Afterward, you can authenticate that file with a single API call to SignetSure's runtime library, making it easy for you to develop secure and reliable software.
Overall, SignetSure is a must-have tool for any developer who wants to keep their subscribers’ and users’ data safe and secure. With its easy-to-use interface and advanced features, SignetSure is an excellent investment that can help you create secure software with complete peace of mind.
