Cryptography is designed to turn information into a format that is difficult to understand in an effort to keep information confidential. Cryptography has been used for centuries, with one cipher being associated with Julius Caesar. Especially over the last few decades, the use and complexity of cryptography has evolved significantly.
As cryptography became a digital security tool, how has its techniques and complexity changed over the last few decades? Conversely, how have cryptographic attacks evolved? How do you think cryptography will evolve in the future?
