|   Warning: this program illustrates how to use low-level functions in the library. It should not be taken as an example of how to build a secure encryption mechanism. To derive a key from a low-entropy secret such as a password, use a standard key stretching mechanism such as PBKDF2 (provided by the `pkcs5` module). To encrypt and authenticate data, use a standard mode such as GCM or CCM (both available as library module). | ||||
