code breaking
Cracking encrypted messages
Code breaking is the practice of deciphering encrypted messages without authorized access to the key or system used to encode them.
The term covers both military intelligence work—cracking enemy communications—and puzzle-solving challenges.
A code breaker analyzes patterns, exploits weaknesses, and tests possibilities: The code breaking at Bletchley Park helped shorten World War II.
Distinct from hacking, which targets computer systems rather than ciphers.
