One type of product simply procedures files and folders, turning them into impenetrable encrypted versions of these. Another creates a virtual disc drive that, when open, acts like any other drive on your system. When you lock the digital drive, each the documents you put into it are completely inaccessible. .
Similar to the digital drive solution, a few goods save your encrypted data in the cloud. This approach requires extreme caution, obviously. Encrypted information in the cloud has a far bigger attack surface than encrypted data on your own PC.

Simply deleting it isn't sufficient, even if you skip the Recycle Bin, since the information still exists on disc, and data retrieval utilities can often get it back. .
Some encryption products avoid this problem by encrypting the document in location, literally overwriting it on disk with an encrypted version. It is more common, though, to offer secure deletion as an option. If you choose a product that lacks this attribute, you ought to find a free secure deletion tool to use along with it. .
Overwriting data before deletion is sufficient to balk software-based recovery tools. Hardware-based forensic retrieval functions since the magnetic recording of data on a hard drive isn't actually digital. It's 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 like a black box. Dump a document, picture, or other document into it, and you get back what sounds like gibberish. Run that gibberish back via the box, with the same password, and you get back the original.

Passwords are important, and you have to 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, register it in an integral exchange, tattoo it on your foreheadwhatever you like. Another is personal, and should be carefully guarded. If I want you could try these out to send you a secret document, I just encrypt it with your public key.
Simple! .
