WebCryptography studies techniques aimed at securing communication in the presence of adversaries. While encryption is probably the most prominent example of a crypto-graphic problem, modern cryptography is much more than that. In this class, we will learn about pseudorandom number generators, digital signatures, zero-knowledge proofs, WebCrypto Presentation templates Who knows what will the future of currency be.
