A person who specializes in creating secret codes, developing encryption systems, or decoding hidden messages.
From 'cryptograph' (secret writing device) with '-er' (one who does), this professional title solidified in the 20th century as cryptography evolved from art to sophisticated mathematical science.
Modern cryptographers use mathematics so complex that the security of your online banking depends on factoring numbers with hundreds of digits—it's math so hard that even all computers combined couldn't break it in reasonable time.
The suffix '-er' and '-grapher' in cryptography traditionally indexed male professionals; cryptographers were predominantly male in academic and military contexts, erasing women's cipher work.
Use 'cryptographer' for any person practicing cryptography; pair with individual names/pronouns to avoid gendered default.
["cipher specialist","encryption expert"]
Women cryptographers including Joan Clarke, Mavis Batey, and many unnamed Bletchley Park operatives broke Enigma codes; institutional history often credits men as sole architects of decryption breakthroughs.
