The problem is that the encryption key is stored on the machine in a local plain text file. Any malware able to read unencrypted local files could obtain the key, and therefore decrypt the messages.

A mistake in the process used by the Signal Desktop application to encrypt locally stored messages leaves them wide open to an attacker.

Researchers have developed a proof-of-concept side-channel attack that allows them to pull encryption keys from a single decryption for a modern version of OpenSSL.

Signal has announced that it upgraded its end-to-end communication protocol to use quantum-resistant encryption keys to protect users from future attacks.

The Signal Protocol used by 1+ billion people is getting a post-quantum makeover Update prepares for the inevitable fall of today's cryptographic protocols.

To guarantee high data security, encryption must be unbreakable while the data remains rapidly and easily readable. A novel strategy for optical encryption/decryption of information has now been ...
