Cryptology is the practice of secure communication through codes and ciphers. The term can be interchangeable with cryptography sometimes. This area of study has gained increased attention in recent times as more sensitive information is being stored online. Synonyms that can be used instead of cryptology include ciphering, encoding, decoding, encryption, steganography, and cryptanalytics. Each of these terms refers to a specific aspect of secure communication. Ciphering or encoding involves converting plaintext to a code or cipher text. On the other hand, decoding means converting the cipher text to plaintext. Cryptanalytics refers to the study of breaking codes and ciphers. The different synonyms provide a nuanced understanding of this vital area of study.
