Microsoft Gave FBI BitLocker Encryption Keys, Exposing Privacy Flaw

The tech giant said providing encryption keys was a standard response to a court order. But companies like Apple and Meta set up their systems so such a privacy violation isn’t possible.

@evacide I still wonder what happened at the end of TrueCrypt, especially since they recommended using Bitlocker when they shut the project down. I've always had the feeling that govt was involved.

VeraCrypt - Free Open source disk encryption with strong security for the Paranoid

VeraCrypt is free open-source disk encryption software for Windows, Mac OS X and Linux. In case an attacker forces you to reveal the password, VeraCrypt provides plausible deniability. In contrast to file encryption, data encryption performed by VeraCrypt is real-time (on-the-fly), automatic, transparent, needs very little memory, and does not involve temporary unencrypted files.
