Chiffry is an encrypted messaging application that provides users with secure communication options. Known for its commitment to privacy and data protection, Chiffry allows users to send text and voice messages, share images, videos, contacts, and locations securely. The app is available for the Android platform, making it accessible for a wide audience who prioritize confidentiality in their communications.

The primary focus of Chiffry is to ensure that all communication remains private and secure. Users can engage in tap-proof phone calls, which are protected by advanced encryption methods. The app utilizes end-to-end encryption, ensuring that messages and calls are encrypted on the sender's device and only decrypted on the recipient's device. This means that neither Chiffry employees nor unauthorized third parties can access the content of the communication.

Chiffry supports various forms of messaging, including voice messages and short text messages. Users can send encrypted messages and notes, ensuring that their conversations remain confidential. The application also facilitates group chats, allowing up to ten members to communicate securely in a single chat room. This feature is particularly useful for teams or groups that require a secure channel for sharing information.

For users who enjoy making phone calls, Chiffry offers the ability to make free phone calls via the Internet. This feature is beneficial for those who want to connect with others without incurring traditional phone call charges. The application’s tap-proof encrypted calls further enhance the security of voice communication.

The security measures employed by Chiffry are robust and adhere to the guidelines set by the German Federal Office for Information Security (BSI). The app uses 256-bit AES encryption in GCM mode, which is a highly secure encryption standard. Each message and phone call is encrypted with a unique key that is regenerated before each communication, ensuring that the security is maintained throughout the conversation.

Data transmission is another area where Chiffry prioritizes security. The application operates through communication servers located in a high-performance data center in Germany. This facility meets stringent security, connectivity, and availability requirements, holding certifications for IT security standard ISO 27001 and management standard ISO 9001. During registration, only the user's telephone number and public keys for communication are recorded on the Chiffry server. Messages are kept in an encrypted state on the server until they are delivered to the recipient and are deleted after delivery or after 21 days.

Chiffry's encryption employs modern elliptic curve cryptography, specifically using 512-bit ECDH for key exchange and 512-bit ECDSA signatures for message authentication. These cryptographic techniques ensure that messages are forgery-proof and that users are reliably identified through encryption certificates. The level of security provided by Chiffry is significantly higher than that used by many online banking services, making it a suitable choice for individuals who require secure communication methods.

Additionally, Chiffry’s user interface is designed to be intuitive, allowing users to navigate the application easily. The basic version of the app is available for free, enabling smartphone users to experience its features without any financial commitment. This accessibility makes it an appealing option for those new to encrypted messaging services.

Chiffry also places a strong emphasis on user privacy, ensuring that personal data is not misused or collected unnecessarily. The app does not store sensitive information beyond what is required for communication, reinforcing its commitment to maintaining user confidentiality.

With its comprehensive set of features, Chiffry is positioned as a reliable choice for individuals and groups seeking secure communication. Whether sending messages, sharing files, or making phone calls, users can trust that their interactions remain private and protected from unauthorized access. The app’s dedication to security and ease of use makes it a valuable tool for anyone concerned about data privacy in their electronic communications.

For those interested in encrypted messaging, Chiffry offers a modern solution that combines advanced security features with user-friendly functionality. By allowing users to download the app on their Android devices, Chiffry promotes a secure communication environment that prioritizes user privacy and data protection. The commitment to maintaining a high standard of security while providing essential messaging features underscores the app's utility in today's digital landscape.
