All Shield communications are end-to-end encrypted with carefully selected and expert-approved encryption algorithms, which keeps CRIP.TO a step ahead of other encryption apps. Every single packet of data sent via Shield is encrypted with a new, different key which changes constantly, thus rendering it almost impossible to decode a whole message, file, or picture.
The Shield app, like many other software encryption apps, uses a Pseudo Random Number Generator to generate the encryption keys. The keys to decrypt the information are known only by the sender and the receiver and are stored inside the Shield app, which is itself protected by two factor authentication.
Unlike Shield, Black enables you to perform all encryption directly on its custom-made Field Programmable Gate Array (FPGA) processor unit and stores all your encryption keys physically in your Black device as opposed to your smartphone. Simply said, it allows you to carry your encryption keys physically in your pocket – the safest place for it with absolutely no outside access.
Thanks to the custom-made FPGA chip, Black is able to use a True Random Number Generator (TRNG) which ensures the highest quality of encryption keys and thereby, the highest level of security for its users.
Black connects easily to your smartphone either via a secure USB cable connection or a user-friendly wireless Bluetooth link, allowing you to use CRIP.TO services seamlessly everywhere.
The sender forwards an encrypted message via Shield or Black to the central server in Iceland. The message is temporary saved (still encrypted) in the server until the receiver comes online, in which case the data is delivered to the receiver and permanently deleted from the server, leaving no traces. The receiver will then be able to decrypt the data with the keys that only they have access to and receive the information.
CRIP.TO servers are physically located in Iceland – a country with perhaps the best legislation for supporting “freedom to speech” and user’s privacy. All this has the effect of ensuring that an entire nation is taking care of your data while temporarily stored on those servers.
