CryptoPro DSS (Digital Signature Server) is a cloud-based service that allows you to use Russian cryptographic algorithms for hash function, digital signature and symmetric encryption on literally any device (laptop, tablet, smartphone) with any platform (Windows, Linux, OS X, iOS, Android, etc.) because everything you need is just any web-browser (Internet Explorer, Chrome, Firefox, Safari, etc.). And you can use any authentication services with SAML 2.0 support (like Gemalto Protiva Strong Authentication Service) for authentication at CryptoPro DSS.
