This document discusses cryptography and some of its key concepts and developments. It covers symmetric and asymmetric encryption, hash functions, digital signatures, and key agreement. It specifically examines the RSA cryptosystem developed in 1977, noting it uses a public and private key approach for encryption, signatures, and key exchange. It also lists some examples of protocols and schemes that employ RSA primitives like SSL, PGP, and digital signature verification.
