<br/><br/> ABSTRACT<br/>The unprotected electronic document may be subjected to a data breach, in which <br/>private or sensitive information is stolen, altered, copied, communicated, viewed, or <br/>used without authorization. This study on Data Protection & Evaluation of <br/>Encryption Algorithms compares four encryption algorithms by performance<br/>evaluation method to know the algorithm that encrypts and decrypts files faster in <br/>different size of the data blocks to determine their performance. The study also <br/>evaluate the four most common encryption algorithms like Rivest Cipher4 (RC4) <br/>Algorithms, Rivest Cpher2 Algorithm (RC2), Advanced Encryption Standard (AES) <br/>and Triple Data Encryption Standard (3DES). These encryption algorithms were <br/>analyzed using different data block sizes ranging from 1MB to 3MB with the help of <br/>a simulation comparison technique to know which among those algorithms <br/>encrypt/decrypt documents faster in terms of performance. Simulation results is <br/>given by demonstrating the effectiveness of each algorithm and recommendation is <br/>given for the fastest in data protection before exposing it online. A cryptography <br/>software prototype that will further showcase sequence, class, storyboard and use <br/>case diagram will be provided. The four Encryption Algorithms were analyzed and <br/>Advanced Encryption Standard (AES) was discovered to encrypt/decrypt faster in<br/>and was chosen for the prototype.<br/>Keywords: Algorithm, Cryptography, Data Protection, Encryption, Evaluation,
