A new development promises to make our mobile conversations nearly impossible to tap into. The solution called CryptTalk can be decrypted of course, but reverse-engineering would take decades, according to its developers.
CryptTalk, developed by Arenim, is not a simple smartphone app, but a communication service system that needs to be activated first. The encryption is using AES-256 and Blowfish-448 methods, the key exchange is based on RSA-4096 standards.
The developers claim that the encryption cannot be cracked even if someone is in possession of the source code and has access to the central server of the service. Voice communication is made directly between the endpoints: conversations are not going through central servers and are not logged either.
