The Evolution of Cryptography

Cryptography has evolved significantly from its early days of simple secret writing to a complex field encompassing various techniques, including encryption and authentication. Initially, cryptography was synonymous with encryption, focusing on methods to obscure messages. However, recent developments have expanded its scope to include digital signatures and advanced techniques like zero-knowledge proofs, demonstrating its vital role in securing not only communication but also computations. The shift toward a more sophisticated understanding of cryptography reflects its increasing importance in maintaining privacy and security in our digital lives.
