THE LATEST SECURITY FUNCTIONS

Chiffry uses the BSI guidelines for encryption and uses the latest end-to-end encryption with 256-bit AES in GCM mode. All messages and phone calls are encrypted on the sender's device and decrypted on the recipient's device. The encryption key is generated anew before each message or telephone call and 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 tamper-proof and every user is identified thanks to Chiffry 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)


SECURE DATA TRANSFER

Chiffry focuses on data protection. The data transfer takes place via the Chiffry communication server. This is located in the high-performance data center of envia TEL, which is one of the safest in Germany and meets the highest requirements for security, connection and availability and is certified according to the IT security standard ISO 27001 & management standard ISO 9001. Only the telephone number and public keys for communication are recorded on the Chiffry server during registration. All messages remain encrypted on the server 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, since the encryption key is only at the sender and recipient in order to encrypt and decrypt information.

- Secure phone calls, encrypted
