cryptology

Cryptology is the study of secure communication techniques that protect information from unauthorized access. It involves creating and analyzing methods to encode messages (encryption) so only intended recipients can understand them. Conversely, it also includes techniques to decode such messages (decryption) and verify their authenticity. Cryptology combines cryptography (building secure systems) and cryptanalysis (breaking them), ensuring data privacy, integrity, and security in digital communications, financial transactions, and more. Overall, it enables confidential and trustworthy exchange of information in an increasingly digital world.
