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 sort of product simply processes files and folders, turning them into impenetrable encrypted versions of themselves. The other creates a virtual disk drive that, when open, behaves like any other drive on your system. When you lock the virtual drive, each the files that you put into it are completely inaccessible. .

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

Just deleting it isn't sufficient, even if you skip the Recycle Bin, because the data still exists on disk, and data retrieval utilities can often return back. .

Some encryption products avoid this problem by encrypting the document in place, literally overwriting it on disc with an encrypted version. It's more common, however, to offer safe deletion as an option. If you select a product that lacks this feature, 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 retrieval functions since the magnetic recording of data on Homepage a hard drive isn't actually digital. It is more of a waveform. In simple terms, the process involves nulling out the known information and reading around the borders of what is left.

An encryption algorithm is similar to a black box. Dump a document, picture, or other file into it, and you get back what seems like gibberish. Run that gibberish back via the box, with the exact same password, and you get back the original.
