Cryptographic systems

Cryptographic systems are the backbone of secure digital communication, ensuring that data remains confidential, authentic, and tamper-proof. These systems employ complex algorithms to encrypt information, making it accessible only to those with the correct decryption key. From protecting sensitive financial transactions to securing personal communications and safeguarding critical infrastructure, cryptographic systems are fundamental in today's interconnected world. They use key principles such as encryption, decryption, digital signatures, and hash functions to provide security services including confidentiality, integrity, and authentication. Whether it's Public Key Infrastructure (PKI) or Advanced Encryption Standard (AES), these systems are crucial for maintaining trust and privacy in the digital realm.
