Abstract: Cryptography is a method of encrypting or decrypting information to conceal its real meaning with other technology and transmit information secretly. In computer science, it refers to utilizing an algorithm that is difficult to decipher, transform messages, and guarantee data security. The Merriam-Webster’s definition of cryptography is the “enciphering and deciphering of messages in secret code” but has recently added the definition “the computerized encoding and decoding of information” to encompass its more commonly known modern definition. The modern definition links cryptography with many more digital terms such as hashes and digital signatures. This section aims to describe a brief history of modern cryptography with a focus specifically on the hash function, public key infrastructure, and digital signature.
