Using a VPN is a terrific way to protect your internet traffic when you're traveling, but it is not a solution for encrypting your regional files. .

When the FBI needed information from the San Bernardino shooter's iPhone, they asked Apple to get a back door to get past the encryption. But no such back door existed, and Apple refused to make one. The FBI had to employ hackers to get into the phone.

Why wouldn't Apple help Because the moment a rear door or comparable hack is different, it will become a target, a prize for the poor guys. It'll flow sooner or later. In a talk at Black Hat this past summer, Apple's Ivan Krstic disclosed that the company has done something similar in their cryptographic servers.

All the products in this roundup explicitly state that they have no rear door, and that's as it ought to be. It does mean that in the event you encrypt an essential document and then forget the encryption password, then you've lost it for good.

Back in the day, in the event that you wanted to maintain a document key you could use a cipher to encrypt it and then burn the original. Or you could lock it up in a protected. The two main approaches in encryption utilities parallel with those options.

One sort of product simply processes files and folders, turning them into impenetrable encrypted versions of themselves. Another creates a virtual disc that, when open, acts like any other drive on your system. When you lock the virtual drive, each of the documents you put into it are entirely inaccessible. .

Similar to the virtual drive solution, a few products store your encrypted information in the cloud. This approach requires extreme caution, obviously. Encrypted data in the cloud has a much larger attack surface than encrypted data on your own PC.

That is better It actually depends on how you plan on using encryption. If you are not sure, take advantage of the 30-day free trial offered by each one of these products to have a sense of the different options.

Once you copy a document into secure storage, or create an encrypted version of it, then you absolutely need to wipe the unencrypted original. Just deleting it isn't sufficient, even if you skip the Recycle Bin, since the information still exists on disc, and data recovery utilities can often get it back. .

Some encryption products prevent this issue by encrypting the document in location, literally overwriting it on disk with an encrypted version. It is more common, however, to offer safe deletion as an option. If you select a product that lacks this feature, you ought to find a free secure deletion tool to use along with it. .

Overwriting information before deletion is sufficient to balk software-based recovery tools. Hardware-based forensic retrieval works because the magnetic recording of data on a hard drive isn't actually digital. It is more of a waveform. In simple terms, the process involves nulling out the known information and reading around the borders of what is left.

An encryption algorithm is similar to a black box. Dump a document, picture, or other document into it, and you get back what seems like gibberish. Run that gibberish back via the box, using the same password, and you get back the original.

The U.S. government has settled on Advanced Encryption Standard (AES) as a standard, and every one the products gathered here support AES. Even those that support other algorithms tend to recommend using AES.

If you are an encryption expert, you may prefer another algorithm, Blowfish, possibly, or the Soviet government's GOST. For the typical user, however, AES is just fine.

Passwords are important, and you must keep them confidential, right Well, not view it when you use Public Key Infrastructure (PKI) cryptography.

With PKI, you get two keys. One is public; you can discuss it with anyone, register it in an integral exchange, tattoo it on your foreheadwhatever you prefer. The other is he said private, and should be closely guarded. If I want to send you a secret document, I simply encrypt it with your public key.

Simple! .

Using this system in reverse, you can make an electronic signature which shows that your document came from you and hasn't been modified. How Just encrypt it with your private key. The simple fact your public key decrypts it is all of the evidence you need. PKI service is less common than support for traditional symmetric algorithms. .

If you want to share a document with someone and your encryption tool doesn't support PKI, there are different options for sharing. Many products allow creation of a self-decrypting executable file. You could also find that the recipient can use a free, decryption-only tool.
