Concepts Of Decoding in Cryptography

Abstract

The internet has arrived at such a stage that it has merged with our daily life, enlarging rapidly in the last few  years. Data security and privacy has become a main risk and threat to everyone who is using or surfing over  the  internet. Data privacy and security makes  sure  that  data  should  only  be accessible by the authorized user & prevents the alteration and modification of message or data. So as to attain this level     of protection and security, various methods and algorithms are developed. Cryptography is a technique of securing data with  the help of algorithms, so that only the intended user  can  process and access that data. The letter suffix ‘graphy’ stands for ‘writing’ and ‘crypt-’ means ‘hidden’. Cryptography is defined as the method that cipher information, depending on particular algorithms and codes make the info unreadable to the human eyes unless it is decrypted back by the codes that were pre decided by the client/sender  .  Cryptography  is  the  technique of writing secure messages and data. Cryptographic algorithms are used to maintain the accounting and integrity of a system. The fundamental usage of cryptography is the capability to transfer data and messages between two parties in such a way that data is inaccessible to the unintended users. This project  will be able to convert web application based encryption and decryption which convert confidential data into unreadable form by using various encryption techniques i.e converting plain text into hashing format). Base32, Base64, Base84 etc. are the few examples of base encryption techniques.
