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.
