Abstract

Currently digital signatures or can also be called digital signatures are increasingly being used, especially for an archive. Digital archival technology is considered as different from traditional archives which refers to the preservation of physical objects such as Photo, Film and Cartography that can carry information. The importance of the right level of security in maintaining the authenticity of the archive requires strong evidence in the form of a digital signature that can be accessed via an Android Smartphone, then the document will be given a digital signature in the form of a hybrid Cryptosystem used for encryption and message description. using the RSA (Rivest Shamir Adleman) algorithm and the AES (Advanced Encryption Standard) algorithm. The reason for using the Hybrid Cryptosystem technique is to make it more secure and efficient.

Abstract

Digital transformation is pushing retailers to adopt online platforms. Hafiz Cell’s offline operations limit market reach and transactional efficiency. This study aims to design and develop an e-commerce website for Hafiz Cell with Midtrans Payment Gateway to enable automated, secure, real-time transactions. The development method uses Extreme Programming (XP), which includes planning, design, coding, and testing. The system is built with Laravel 10 and supported by MySQL for data storage, Cloudinary for media management, and RajaOngkir for shipping cost estimation. Implemented features include product management, cart, checkout, automatic payments through Midtrans (QRIS, e-wallets, bank transfer, credit cards), and an admin dashboard. Black-Box Testing across core modules (homepage, profile, catalog, cart, checkout, payment, order history, and admin pages) shows all scenarios work as expected. The implementation improves transaction efficiency, reduces recording errors, and expands market reach through 24/7 availability. These results indicate that the combination of Laravel and Midtrans, together with XP, is effective for building a functional, production-ready e-commerce system for SMEs.
