Chiffry Secure Messenger is the first app with the quality label "IT Security made in Germany", which allows you a safe and comprehensive communication. With Chiffry you can make tap-proof phone calls, send your photos, videos, contacts, voice and text messages confidentially. All data will be securely transmitted using state-of-the-art end-to-end encryption (256 bit AES - GCM 512 bit ECDH) and digital signatures (512 bit ECDSA). With Chiffry you can also read standard and custom QR-Codes! Chiffry is available for: - Windows Phone (No longer in development, only security and certificate updates, limited functionality.) - Android - BlackBerry - iOS For information security the following key lengths and encryption methods are used: Chiffry uses elliptic curve cryptography (ECC) and the industry standard AES. The key lengths used correspond respectively to 15,500 bit RSA keys (Source: BSI TR 02102-1). Other service providers offer usually security equal to a maximum of 4,096 bit RSA keys. According to the BSI (Federal Office for Information Security) directive "BSI TR-03111" the recommended ECC curve "brainpoolP512r1" for asymmetric functions is exclusively used.
