CRYPTOGRAPHY: ENHANCING DIGITAL DATA SECURITY WITH OPENSSL

Abstract

This study explores the fundamentals of cryptography, its evolution throughout history, and contemporary cryptographic algorithms. In today's digital era, cryptography is crucial for securing data. Additionally, practical applications utilizing OpenSSL are demonstrated to highlight cross-platform implementation. Encryption and decryption implementations using AES-256-CBC and RSA Public Key are presented. The study also addresses the dangers associated with unsecured data, emphasizing the importance of robust encryption techniques. Issues such as quantum computing and the future of post-quantum cryptography are also discussed. The findings indicate that continuous advancements in cryptographic techniques are essential to safeguarding sensitive data from escalating cyber threats.
