The study and practice of analyzing and breaking codes or ciphers used in secret communication.
Cryptanalysis is essential for understanding how secure communication can be compromised.
Cryptanalysis → It is formed from "crypto-" (from Greek "kryptos", meaning hidden) and "analysis" (from Greek "analusis", meaning a breaking up or loosening). The word refers to the process of breaking down or analyzing hidden or encoded information.
Think of 'hidden' ('crypto-') information being 'broken down' ('analysis') — that's what cryptanalysis means.
