Pretty Good Privacy on Online Shopping

ABSTRACT - This study investigates the integration of Pretty Good Privacy (PGP) encryption into e-commerce platforms, focusing on the use of RSA, AES and SHA-256 cryptographic algorithms. PGP enhances the security of online communications and transactions by combining symmetric encryption (AES), asymmetric encryption (RSA) and secure hashing (SHA-256). These mechanisms work together to ensure data confidentiality, authentication, and integrity. The paper presents the principles behind PGP, details the encryption and hashing techniques and examines their practical application in securing e-commerce transactions. Key Words: Pretty Good Privacy (PGP), RSA, AES, SHA-256, Product Authentication, Digital Signatures, Public-Key Cryptography, E-commerce Security, Data Integrity, Online Shopping.
