File encryption or data encryption is a process of transforming your confidential information into an unreadable format which cannot be accessed without correct password or key. It is used in the field of Cryptography which is the science of information security. The information is converted by using a special algorithm which is known as Cipher and cipher makes your data inaccessible for all those people who do not have the correct password or the key.

This procedure of translating your data into indecipherable format is completed by following a proper series of well-defined steps; these steps in turn result in coded information or you can say encrypted information. This encrypted information in cryptography is called as Cipher text.

The purpose of cryptography or file encryption software can be defined as follow:

  • Confidentiality: It means complete privacy and secrecy of your information in such a way that it cannot be understood by those for whom it was not intended.
  • Integrity: It means that encrypted information cannot changed, altered or modified in anyway. Your encrypted information will remain intact in storage containers and in transit between sender and intended receiver.
  • Non- refutation: It means that sender or the creator of the information later cannot deny his or her purpose of creating and sending the encrypted information.
  • Verification: It means authentication is required so that sender and receiver can confirm each other’s identity as well as the origin and destination of the information.
Dating back to early 1970’s, file encryption software were symmetric in nature which means that the key used to encrypt files and folders was the same as the key which was used to decrypt the encrypted information.

Decryption is basically the process of decoding encrypted information that has been previously transformed into a secret format and this decoding requires a password or a secret key.

Asymmetric algorithm was introduced in 1977 by two American mathematicians W. Diffie and M. E. Hellman. Asymmetric algorithm requires two different keys which are mathematically interrelated but cannot be derived from one another.  One key is used for encrypting data while the other key is used to decrypt the encrypted data or information.

Encryption algorithm is conceived to be sensibly secure practice to keep your data safe and protected. There are many encryption algorithms being used in the industry these days which include 64-bit encryption, 128-bit encryption, and 256-bit encryption. Out of them 256-bit encryption algorithm is considered to be most secure and reliable algorithm.

Advanced Encryption Algorithm known as AES is now considered to be most reliable encryption algorithm among all the algorithms available till date. Many file encryption software are deploying this encryption algorithm which makes them even more secure and more reliable when it comes to encrypting confidential data.

Folder Lock is a file encryption software that uses 256-bit AES encryption algorithm that makes it secure and reliable. It is an advanced level of file encryption software that also offers a simple way to lock down personal files and folders so that it will be useful for the techies as well as for casual home users.

It comes with many other useful features which make it stand out of the other ordinary file encryption software like file shredding, stealth mode, USB portability which lets you secure USB drive, hack attempt monitoring, history cleaning, plug & play support and many more. You must got to give it a try!
