The process of converting information into a code to keep it secret.
The encipherment of the message ensured that only the intended recipient could read it.
Encipherment → It is formed from "en-" (meaning to cause to be) and "cipher" (from Old French *cifre*, meaning a code or zero). The suffix "-ment" (meaning the action or result of) indicates the process of converting information into a coded format. Thus, encipherment refers to the process of converting plain text into a coded message.
Think of 'causing to be' ('en-') a 'code' ('cipher') — that's how encipherment means the process of turning information into a code.
