I’ve got an external hard drive (8TB) filled with videos. My attack scenario: preventing illegal search and seizure and fishing expeditions by law enforcement. My use case: personal video library served up by Plex. Platform: Microsoft Windows 10 Pro.
I’m aware of Bitlocker, but I’m not sure I can trust it not to have backdoor access. I’ve heard of Veracrypt, but I don’t know if that’s still considered a best practice/tool for disk encryption.
I’m also running automated backups of the data on that external disk to another external disk of the same size. Those backups are encrypted at the application layer (by Arq backup), so I don’t need disk-level encryption there – just on the source disk itself.
What’s a good tool that’s maintained, audited/trustworthy and efficient for transparently encrypting/decrypting files on that external disk? What’s the best practice these days? It’s been years since I last looked at this.
