Using a VPN is a great way to shield your internet traffic when you're traveling, but it's 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. However, 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 Since the moment a back door or similar hack exists, it becomes a target, a decoration for the bad guys. It'll leak sooner or later. In a talk at Black Hat last summer, Apple's Ivan Krstic revealed that the company has done something similar in their cryptographic servers.

Apple can't update them, but the bad guys can't get in either. .

Each the products in this roundup explicitly state that they have no back door, and that is as it ought to be. It does mean that if you encrypt an essential document and then forget 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 protected. The two main approaches in encryption utilities parallel these options.

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

Like the virtual drive solution, some products save your encrypted information in the cloud. This strategy requires extreme caution, obviously. Encrypted data in the cloud has a far bigger attack surface than encrypted data on your own PC.

Which is better It actually depends on how you plan to use encryption. If you're not sure, take advantage of the 30-day free trial provided by each of these products to get get more a sense of the different options.

After you copy a file into protected storage, or create an encrypted version of it, then you definitely need to wipe out the unencrypted original. Simply deleting it isn't sufficient, even if you bypass the Recycle Bin, because the information still exists on disc, and data recovery utilities can often return back. .

Some encryption products prevent this problem by encrypting the file in location, literally overwriting it on disc using an encrypted version. It is more common, though, to offer secure deletion as an option. If you select something that lacks this attribute, you ought to 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 recovery works since the magnetic recording of information on a hard drive isn't actually digital. It is more of a waveform. In simple terms, the procedure involves nulling out the known data and reading around the edges of what is left.

An encryption algorithm is similar to a black box. Dump a document, image, or other document into it, and you get back what sounds like gibberish. Run that gibberish back via the box, using the exact 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 accumulated here service AES. Even those that support other calculations 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 average user, however, AES is just fine.

Passwords are important, and you must 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 a key exchange, tattoo it on your foreheadwhatever you like. The other is personal, and should be carefully guarded. If I want to send you a secret document, I just encrypt it with your public key.

Simple! .

Using this program in reverse, you can create an electronic signature that shows that your document came from you and hasn't been altered. How Exactly To encrypt it with your private key. The simple fact that your public key decrypts it is all the proof you need. PKI service is less common than support for traditional symmetric algorithms. .

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