About this course
Cryptography is the science of protecting information, and it runs silently beneath everything digital: the padlock in the browser, the encrypted messages, the passwords, the digital signatures. This course teaches the complete journey: the history of ciphers, the mechanics of encryption, symmetric and public-key systems, hashing, and the real-world protocols, TLS, certificates, and digital signatures, that protect modern data.
