摘要

Cryptography paved the way for making communication more secure by hiding information in a communicated message or making it incomprehensible, which has evolved since ancient times, with each era embracing technological advancements that make encryption and decryption more complex and secure. The application of Cryptography also varies with each era. The technology was primarily used in military and religious communication during ancient and medieval times. The governments and religious institutions found it secure to share sensitive information such as military campaign communication as encryption. The modern era also embraced a similar trend with most Cryptography usage experienced during World War II. Such also influenced the introduction of a cipher. The contemporary era paved the way for the introduction of cryptocurrency widely used, given the advantages involved. The transformation of cryptography captures the historical relevance of the technology across different settings. This essay focuses on reviewing the history of cryptography and its applications.
