Abstract- Cryptography plays a critical role in modern information security, safeguarding communications and data in an increasingly interconnected world. From classical encryption techniques to modern symmetric and asymmetric systems, cryptography underpins essential services such as online commerce, secure messaging, and password protection. With the rise of sophisticated cyber threats—including data breaches, denial of-service attacks, and identity theft—ensuring data confidentiality, integrity, authentication, and non-repudiation has become paramount. Although contemporary cryptographic systems offer robust protection, vulnerabilities often lie outside these schemes, necessitating broader security strategies. The advancement of quantum computing introduces both challenges and opportunities, especially with quantum key distribution (QKD) offering unprecedented levels of secure communication. Continued research in classical and quantum cryptography remains vital to addressing current and emerging security needs in digital communication and commerce.
