Two Main Approachesīack in the day, if you wanted to keep a document secret you could use a cipher to encrypt it and then burn the original.
It does mean that if you encrypt an essential document and then forget the encryption password, you've lost it for good, however. As my colleague Max Eddy pointed out in a past article about one-time Attorney General Barr's ignorance of encryption, "a back door is still a door and even a door with a lock on it can be opened."Īll the products in this roundup explicitly state that they have no back door, and that's as it should be.

Whole-disk encryption is an effective line of defense for a single device, but it doesn't help when you need to share encrypted data. In this roundup, we're specifically looking at products that encrypt files, not at whole-disk solutions like Microsoft's Bitlocker. File Encryption, Whole-Disk Encryption, and
