What does cryptography mean?

Cryptography, or cryptology(from Ancient Greek: κρυπτός, romanized: kryptós"hidden, secret"; and γράφεινgraphein, "to write", or -λογία-logia, "study", respectively), is the practice and study of techniques for secure communicationin the presence of adversarialbehavior.

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.
