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

When the FBI needed information from the San Bernardino shot's iPhone, they asked Apple for a rear 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 rear door or comparable hack exists, it becomes a goal, a prize for the bad guys. It will flow sooner or later. In a discussion at Black Hat this past 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. .

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

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

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

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

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

Once you copy a file into secure storage, or make an encrypted version of it, you definitely need to wipe out the unencrypted original. Just deleting it isn't sufficient, even in the event that you bypass the Recycle Bin, because the data still exists on disk, and data retrieval utilities can often get it back. .

Some encryption products avoid this problem by encrypting the document in place, literally overwriting it on disk using an encrypted version. It is more common, though, to provide secure deletion as an option. If you select something that lacks this feature, you ought to find a free secure deletion tool to use along with it. .

Overwriting data before deletion is sufficient to balk software-based retrieval tools. Hardware-based forensic retrieval works because the magnetic recording 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 data and reading around the borders of what's 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 through the box, with the same password, and you get back the original.

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

If you're an encryption specialist, you might want another algorithm, Blowfish, possibly, or the Soviet government's GOST. For the average consumer, 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 discuss it with anyone, enroll it in a key exchange, tattoo it on your foreheadwhatever you like. Another is personal, and should be closely guarded. If I want to send you a key document, I just 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 is all the evidence you need. PKI service is less common than service for traditional symmetric algorithms. .

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