PRODUCT DESCRIPTION

 

Chiffry Secure Messenger is an app for smartphones with which you can communicate confidentially and securely. Thanks to the latest encryption standards, you can:

- send messages securely
- share confidential pictures, videos, contacts and locations
- make tap-proof phone calls

The Chiffry Basic version is the free, tap-proof Whatsapp alternative for those who value security and privacy. This encrypted messenger is available for Android, iOS and Windows Phone. It allows private individuals, companies and authorities to share information confidentially.

When it comes to encryption, Chiffry follows the BSI guidelines and uses state-of-the-art end-to-end encryption with 256-bit AES in GCM mode. All messages and telephone calls are encrypted on the sender's device and decrypted on the recipient's device. The encryption key is regenerated before each message or telephone call and transmitted to the recipient according to the letterbox principle using modern elliptic curve cryptography (512-bit ECDH).

In addition, all messages are forgery-proof with 512-bit ECDSA signatures and each user is identified thanks to cipher certificates. For comparison: online banks usually use 2,048 to 4,096-bit RSA encryption. The 512-bit EC encryption used by Chiffry corresponds to 15,500-bit RSA encryption. The effort to guess this key is at least 3.4*1038 times higher. (Sources: BSI TR-02102-1, TR-03111)
