Why is cryptography important?

C ryptography is fundamental to many information security and privacy mechanisms. Today, a variety of cryptographic algorithms are used in many different applications. This article explains cryptography: how it works, key principles or operations of cryptography, types of cryptography, use cases and more! What is cryptography?

When did cryptography start?

Extensive open academic research into cryptography is relatively recent, beginning in the mid-1970s. In the early 1970s IBMpersonnel designed the Data Encryption Standard (DES) algorithm that became the first federal government cryptography standard in the United States.
