Using a VPN is a great way to protect your internet traffic when you're traveling, but it is not a solution for encrypting your local 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. However, no such back door existed, and Apple refused to create 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 is different, it becomes a goal, a prize for the poor guys. It will flow 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 them, but the poor guys can't get in either. .
Back in the day, in the event that you wanted to keep a document key 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 approaches in encryption utilities parallel these options.
One type of product simply procedures files and folders, turning them into impenetrable encrypted versions of themselves. Another creates a virtual disk drive that, when open, behaves like any other drive on your system. When you lock the virtual drive, all the files you put into it are entirely inaccessible. .
Similar to the digital drive solution, some goods save your encrypted data in the cloud. This strategy demands extreme care, 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 to use encryption. If you're not sure, take advantage of the 30-day free trial offered by each one of those products to have a sense of the different options.
After you copy a file into secure storage, or make an encrypted version of it, then you absolutely need to wipe the unencrypted original. Just deleting it isn't sufficient, even if you bypass the Recycle Bin, since the information still exists on disc, and data recovery utilities can often get it back. .
Some encryption products avoid this problem by encrypting the file in location, literally overwriting it on disc using an encrypted version. It's more common, however, to offer safe deletion as an option. If you select something that lacks this attribute, you should find a free secure deletion tool to use his response along with it. .
Overwriting information before deletion is sufficient to balk software-based recovery tools. Hardware-based forensic retrieval functions since the magnetic recording of information on a hard drive isn't actually digital. It is more of a waveform. In simple terms, the process 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 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 all of the products gathered here service AES. Even those that support other algorithms tend to recommend using AES.
If you are an encryption expert, you might prefer another algorithm, Blowfish, possibly, or the Soviet government's GOST. For the average 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 receive two keys. One is public; you can share it with anyone, enroll it in an integral exchange, tattoo it on your foreheadwhatever you like. Another is personal, 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 program in reverse, you can create an electronic signature which proves your document came from you and hasn't been modified. How Exactly To encrypt it with your private key. The fact your public key decrypts it is all of the proof you need. PKI support is less common than support for traditional symmetric algorithms. .
If you want to talk about a file with someone and your encryption application doesn't support PKI, there are other 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.
