About this app

CryptoKey is the latest mobile application that allows you to sign documents with an electronic signature simply, conveniently and as securely as possible.
The application allows you to sign documents with a qualified and unqualified electronic signature using keys created directly from a mobile device.
Documents can also be signed using hardware tokens connected to a mobile device via a wire or contactlessly via NFC.
The solution uses modern distributed key storage technology, which provides a completely new level of security previously unavailable in other means of electronic signature from a smartphone.
Your keys are reliably protected and cannot be accessed by an intruder not only in the event of loss or theft of a mobile device, but also in the event of a complete compromise of server components or the presence of malware on the smartphone.
