Using a VPN is a terrific way to shield 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 for a rear door to get beyond the encryption. But no such back door existed, and Apple refused to make one. The FBI had to hire hackers to get into the phone.

Why wouldn't Apple help Because the moment a back door or similar hack is different, it will become a target, a decoration for the bad guys. It'll leak sooner or later. In a talk at Black Hat this past summer, Apple's Ivan Krstic revealed the company has done something similar in their cryptographic servers.

Apple can't update thembut the bad guys can't get in either. .

All the products in this roundup explicitly state they have no back door, and that is as it should be. It does mean that in the event you encrypt an essential document and then forget that the encryption password, then you have lost it for good.

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

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

Like the virtual drive solution, a few goods save your encrypted data in the cloud. This strategy demands extreme care, obviously. Encrypted data in the cloud has a far bigger attack surface than encrypted data on your own PC.

Which is better It really depends on how you plan to use encryption. If you're not sure, take advantage of this 30-day free trial offered by each one of these products to get 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. Simply deleting it isn't sufficient, even in the event that you bypass the Recycle Bin, since the data still exists on disc, and data retrieval utilities can often return back. .

Some encryption products avoid this issue by encrypting the file in place, literally overwriting it on disk using an encrypted version. It is more common, however, to provide secure deletion as an option. If you choose a product that lacks this feature, you should find a free secure deletion tool to use along with it. .

Overwriting information before deletion is sufficient to balk software-based retrieval tools. Hardware-based forensic retrieval functions since the magnetic recording i was reading this of information on a hard drive isn't actually digital. It's more of a waveform. In simple terms, the procedure involves nulling out the known information and reading around the borders of what is left.

An encryption algorithm is like a black box. Dump a document, picture, or other file into it, and you get back what sounds like gibberish. Run that gibberish back through 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 all of the merchandise gathered here support AES. Even the ones that support other algorithms tend to recommend using AES.

If you're an encryption expert, you might want another algorithm, Blowfish, possibly, or even the Soviet government's GOST. For the typical consumer, however, AES is just fine.

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

With PKI, you get two keys. One is public; you can share it with anyone, register it in an integral exchange, tattoo it on your foreheadwhatever you prefer. Another is personal, and should be carefully 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 create a digital signature that proves your document came from you and hasn't been modified. How Just encrypt it with your private key. The fact that your public key decrypts it's all of the evidence you need. PKI support is less common than service 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.
