Cryptography

"In a world full of noise, cryptography is the whisper only the worthy can hear"

What is cryptography

Cryptography is a field of study, where we primarily focused on securing data by transforming it to ensure confidentiality, integrity, authenticity, and non-repudiation.
It uses mathematical techniques and algorithms to protect information during storage and transmission against unauthorized access or tampering.

(As you know, we are now going to take a deep dive into the sea of cryptography. Same as we do on another topics.)
