End-to-end encryption is a method used to secure data, particularly messages, in such a way that only the communicating users can read them. The information is encrypted on the sender’s side and only decrypted on the receiver’s end. Even BUMF Chat servers, or any intermediary, cannot decrypt and read the content. It’s like sending a sealed envelope that only the recipient can open.

BUMF Chat’s E2EE ensures that your data is encrypted from the moment it leaves your device until it reaches the intended recipient’s device.

• Keys and Encryption: The heart of E2EE in BUMF Chat is the generation of secure encryption keys. When a user creates an account, a pair of public and private keys is generated. The public key is shared with other users, while the private key remains on the user’s device. When a message is sent, it is encrypted using the recipient’s public key. Upon arrival, the recipient’s private key decrypts the message.

• Perfect Forward Secrecy (PFS): BUMF Chat ensures that even if an attacker were to compromise encryption keys, they would only be able to access a limited amount of data. This is achieved through PFS, where temporary encryption keys are generated for every session, ensuring that past communications remain secure even if a key is compromised in the future.
