haydIT : An Encryptor and Decryptor Application

Abstract

Encryption is a method of hiding data so that it cannot be read by anyone who does not know the key. The key is used to lock and unlock data. In a hack-prone society like ours now, this method would prevent unauthorized individuals from understanding your most protected correspondences. Hence, the development of an encryptor and decryptor is necessary. haydIT offers a user-friendly interface using intuitive icons that most of us are familiar with. Users can encrypt data, generate private key that serves as a unique lock of encryption, and send it thru any means to its recipient. Receivers can also use the same system to decrypt the data using the private key that must be manually entered to the system. haydIT prides itself in supporting the conversion of different language scriptures, providing asymmetrical way of data conversion through double encryption of randomly selected characters. It also supports multi- level of encryption and applies parity checking for data integrity. Thus, provides a virtually- pattern-less way of encoding and decoding data. The developers utilized the Spiral Methodology in developing the project. It combines the elements of both design and prototyping-in-stages, in an effort to combine advantages of top- down and bottom-up concepts. The developed PC app was tested by 15 IT Professionals based on several metrics and proved that haydIT is performing efficiently as expected with a grand mean of 4.75 interpreted as Excellent. With haydIT, everyone can guarantee that messages will be understood only by its intended reader.
