Encryption software comprise algorithms that allow you to secure all your sensitive, critical, or confidential data by breaking up data in such a manner that it would require a key to recover the actual data stored in the encrypted format. These tools are popularly used, in recent years, to protect data; especially, when it is transmitted or transferred via email or other communication channels. Encryption tools offer the capability to encrypt as well as decrypt the data. Some tools offer the capability to decrypt the data with just a key and do not require the existence of the application in the receiver’s system. Another prominent functionality included in these tools is the file shredding function that ensures that even deleted files are secured to prevent retrieval.
