Advanced cryptography

Advanced cryptography involves complex techniques to secure data, ensuring confidentiality, integrity, and authenticity. It uses mathematical algorithms such as elliptic-curve cryptography (ECC) and post-quantum cryptography to protect information against modern threats and potential quantum computing attacks. Key concepts include asymmetric encryption (public and private keys), hashing functions for data integrity, and digital signatures for authentication. These methods are foundational in securing communications and data in a digital world.
