The process of protecting information by transforming (encrypting) it into an unreadable format is called cryptography. Only those who possess secret key can decipher (decrypt) the message into plain text. Encrypted messages can sometimes be broken by cryptanalysis, also called code breaking, so there is a need for strong and fast cryptographic methods for securing the data from attackers. Although modern cryptography techniques are virtually unbreakable, sometimes they also tend to attack.As the Internet, big data, cloud data storage and other forms of electronic communication become more prevalent, electronic security is becoming increasingly important. Cryptography is used to protect e-mail messages, credit card information, corporate data, cloud data and big data so on... So there is a need for best and fast cryptographic methods for protecting the data. In this paper a method is proposed to protect the data in faster way by using classical cryptography. The encryption and decryption are done in paralleln using threads with the help of underlying hardware. The time taken by sequential and parallel method is analysed.
