encrypt

/ɪnˈkrɪpt/
IELTSAcademic
verb

To turn information into a code so that only people with the right key can read it. People encrypt files, messages, and data to protect privacy or security.

  • Please encrypt the file before sending it.
  • The app encrypts your messages automatically.
  • Banks encrypt customer data for safety.

Adinary Nuance

Encrypt is more specific than hide or lock. You use it when information is changed into code, usually for digital security. It is not the same as encode, which can mean putting something into a different form, not always for protection. In formal or technical writing, encrypt is the clearest word when secrecy and security matter.
