cryptologist

This term refers to a professional or academic specialist in the science of secret writing. While often used interchangeably with cryptographer, a cryptologist typically encompasses both the creation of codes (cryptography) and the breaking of them (cryptanalysis), representing a broader theoretical and practical mastery of the field.

In modern usage, the term is frequently associated with national security, intelligence agencies, and cybersecurity firms. It carries a connotation of high technical expertise and intellectual rigor, often implying a background in advanced mathematics or computer science.
