Encryption Software: A Pervasive Solution to Protect Important Data

Encryption software is a software that encrypts files and data for security purposes. The software uses a key or a password to secure data. It helps in securing privileged information shared as an email attachment or through USB. Encrypted text is known as cipher text. Known human languages are incapable to access this sensitive information, because readable text is converted into cipher text using a software program. In the first step, a mathematical logic or an algorithm is used to convert readable text into encrypted format. In the next step, decryption is needed to read the file. 

Encryption in history:

In ancient times, Scytale, consisting of a piece of parchment paper wrapped around cylinder of specific diameter was used. Recipient needed to unwrap parchment around the cylinder with similar diameter. The encrypted text was read while unwrapping the parchment. In this method, the diameter of the cylinder was the key. Another method for encryption was known as Ceasar cipher. In this method, number of places were shifted on either direction, left or right side. The decryption was possible only when a recipient knew the direction and the number of shifts. 

Encryption in modern times:

Specialized programs are entering in the market that ensure security for emails, files, and data. Some of the software programs need same software on recipient’s side to decrypt; while some software programs allow other software programs to decrypt. This is beneficial while sending a file through email. There are two types of keys are used – symmetric keys and asymmetric keys. In symmetric key method, sender and recipient use same keys on both sides to decrypt data. On the other hand, in asymmetric key method, both of them use different keys on their sides to decrypt data. 

Features of encryption software:

• It protects files through password and allows access, modification, and browsing only when a correct password is entered. Otherwise, files are hidden, locked, or inaccessible.
• Data backups are provided with the help of USB, flash drive, DVD, and others to ensure better security and integrity of data. 
• Creating a huge number of files on encrypted drive is possible and sometimes, it also works as a virtual drive on computer. 

Types of encryption software:

• Single user file:

When a single user intends to decrypt a single file or multiple files using a key or password, then it is known as a single user file. Only one user is allowed by software to access and modify information by accessing the file through key. 

• Multi-user file

When multiple users with a key or a password are encrypting a file, then it is known as multi user file. The software uses multiple keys or a shared key to provide access to multiple users.
 

• Database

Encryption in database is done in two ways. An information is encrypted before putting into the database, and the other way involves encryption application that encrypts information at the same time it is written or read.
