Comparative Analysis of Encryption Algorithms Against Text Files

The proliferation of technology and vast amount of data transferred every day has made it imperative to practice security measures to protect people and their information. This issue has been handled by the implementation of cryptography in exchange of data. However, there exist many algorithms that can be used to encrypt and decrypt information and choosing the right one for a specific task is crucial. This paper focuses on effectively comparing four popular encryption ciphers, namely RSA, DES, Triple DES and Blowfish, through a web application that allows for measuring various factors of encryption, to provide a graphical result of the best algorithm to use for encrypting text files.
