This 43-minute DevConf talk by Dr. Uma Pujeri traces the evolution of encryption technologies from historical methods to cutting-edge approaches. Journey through the development of cryptographic systems, beginning with basic Caesar ciphers and substitution techniques before exploring how modern computing transformed the field with symmetric key algorithms like DES, 3DES, and AES. Discover the revolutionary impact of asymmetric encryption systems such as RSA and Diffie-Hellman key exchange, and learn about emerging technologies including quantum-resistant and homomorphic encryption designed to address contemporary security challenges. The presentation also features Dr. Pujeri's original "Symmetric Encryption Algorithm using ASCII Values" with implementation details. Access accompanying slides and resources through the provided DevConf link to deepen your understanding of how encryption continues to evolve in response to our changing technological landscape.
