Encrypted chat

Secure instant chat

No.1 BC chat is a one-time encrypted conversation between two people. No.1 BC uses hybrid encryption which is made of complex mathematical data processing functions. End-to-end encryption approach ensures that the message is encrypted on one end and decrypted only on another end. No chat history. No chat logs.

Message encryption and decryption is possible only with No. BC cards. Non-No.1 BC users cannot join and cannot be invited to the chat. Men attempting to be in-the-middle will envy how secure your communication is, because they will not get a bit of your information.

Encrypted phone calls

Real-time voice encryption

No.1 BC uses multi-layered encryption environment for secure transmition of real-time voice calls. Combination of asymmetric and symmetric encryption ensures strong protection and high speed of data processing. Regular mobile channels are not secure and if you don’t take care of security yourself — nobody will. Don’t wait until it’s too late!

Hardware and network

No.1 BC is secured on all levels: software, hardware and network infrastructure. It uses secure server connectivity with strict policies on traffic and data transfer. In addition to all, encryption component (No.1 BC card) is hidden inside of your regular phone. Visually it will look just like many other mobile phones and nobody will even guess what exactly you are using.

Secure file transfer

Sending files

You can send files via secure No.1 BC environment and be sure that what you send on one end will be received only on another end. Interception of encrypted data “on the go” is absolutely useless. Only intended user will receive.
