• Subfields include encoding, decoding, cryptanalysis, codes, ciphers, etc.
• In many languages, though less so in English, cognates to "cryptology" are also used with the meaning given above, and even preferred.
• Related to cryptography but distinct, steganography is the art and science of writing hidden messages in such a way that no-one apart from the sender and intended recipient even realizes there is a hidden message.
