MOST MODERN SECURITY FUNCTIONS
For encryption, Chiffry follows the BSI guidelines and uses the latest 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 is transmitted to the recipient according to the mailbox principle using modern elliptic curve cryptography (512-bit ECDH). In addition, all messages with 512-bit ECDSA signatures are forgery-proof and every user is identified thanks to encryption certificates. For comparison: online banks generally 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)
SECURE DATA TRANSMISSION
At Chiffry, data protection is a priority. The data transfer is carried out via the Chiffry communication servers. Those are located in envia TEL's high-performance data-centre, which is one of the most secure in Germany and meets the highest requirements for security, connectivity and availability. It is certified according to IT security standard ISO 27001 & management standard ISO 9001. Only telephone number and public keys for communication are recorded on the Chiffry server during registration. All messages remain on the server in an encrypted state until they are delivered to the recipient and are deleted after delivery or after 21 days at the latest. End-to-end encryption means that neither Chiffry employees nor third parties can access the content of these messages, as the encryption key is only located at the sender and recipient's premises to encrypt and decrypt information.

Can use again The application icon had disappeared sometime after the last update. Rooted Samsung Galaxy S5 Android 5.0. Update: Uninstalled then reinstalled and icon reappeared. I wonder if ART odexing corrupted the file when I updated my system partition.
