cryptographs
Secret written codes
Cryptographs are messages written in code or cipher—text that has been transformed to conceal its meaning from unauthorized readers.
The term also refers to devices or systems used to produce such coded messages.
The spy's cryptographs remained unbroken for decades.
The singular cryptograph can mean either a single encoded message or the apparatus that creates one.
