cryptologic
Concerning secret codes
Cryptologic relates to cryptology—the science of making and breaking codes and ciphers.
The term appears most often in military and intelligence contexts: cryptologic operations, cryptologic analysts.
The National Security Agency describes itself as a cryptologic organization.
Also spelled cryptological.
