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 local files. .
When the FBI needed information from the San Bernardino shot's iPhone, they asked Apple to get a back door to get beyond the encryption. But 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 rear door or comparable hack is different, it becomes a goal, a decoration for the bad guys. It'll leak sooner or later. In a discussion at Black Hat this past summer, Apple's Ivan Krstic disclosed 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. .
Back in the day, in the event that you wanted to keep 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 those options.
One type of product simply processes files and folders, turning them into impenetrable encrypted versions of these. Another creates a virtual disk that, when open, behaves like any other drive on your system. When you lock the virtual drive, each the files you put into it are 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 far bigger 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 one of these products to have a sense of the different options.
Once you copy a document into secure storage, or make an encrypted version of it, then you absolutely need to wipe out the unencrypted original. Simply deleting it isn't sufficient, even if you bypass the Recycle Bin, because the data still exists on disk, and data recovery utilities can often get it back. .
Some encryption products prevent this issue by encrypting the file in location, literally overwriting it on disc using an encrypted version. It's more common, though, to offer safe deletion as an option. If you select a product that lacks this attribute, you should 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 recovery functions since the magnetic recording of data on a hard drive isn't actually digital. It is more of a my blog waveform. In simple terms, the procedure involves nulling out the known information and reading around the edges of what's left.
An encryption algorithm is like 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 depended on Advanced Encryption Standard (AES) as a standard, and all the products accumulated here service AES. Even those that support other algorithms tend to recommend using AES.
If you're an encryption expert, you may prefer another algorithm, Blowfish, perhaps, or the Soviet government's GOST. For the typical user, however, AES is just fine.
Passwords are important, and you must keep them secret, 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 prefer. Another is private, and needs to be carefully guarded. If I want to send you a key document, I simply encrypt it with your public key.
Simple! .

Using this program in reverse, you can create a digital signature that proves your document came from you and hasn't been altered. How Just encrypt it with your private key. The fact your public key decrypts it's all of the proof you need. PKI service is less common than support for traditional symmetric algorithms. .
If you want to share a file with someone and your encryption tool doesn't support PKI, there are other options for sharing. Many products allow creation of a self-decrypting executable file. You may also find that the recipient can use a complimentary, decryption-only tool.
