The Bytejailcore audit is our most comprehensive investigation to date, and we are happy to say that we did not find any security-affecting vulnerabilities or cryptographic weaknesses.
We also did not find any code that could expose the user's credentials or encryption keys to an outside system, trusted or otherwise. (In other words, we did not find anything resembling an intentional or unintentional backdoor.)
Even though we did find a few very minor issues with some parts of the code, they were addressed correctly in less time than it took us to find and analyze them. This shows a commitment to secure software development and demonstrates the willingness to listen to security researchers.
