Secret Writing

Secret writing involves encoding messages so they are only understood by the intended recipient. This can be achieved through various methods, such as ciphers, codebooks, or hidden messages. The goal is to protect information from unauthorized access, ensuring privacy and security. Techniques range from simple substitutions, where letters are replaced with others, to complex algorithms that scramble data mathematically. Secret writing has been used historically in espionage, military communication, and personal privacy, and remains fundamental to modern encryption systems that safeguard digital data.
