# Encrypt Example

    library(deident)

The most direct method of removing identifiability is via ‘encryption’ which comprises two processes:

1. The ‘salting’ of a string by appending a given, unknown string.
2. The ‘hashing’ of the resulting string via an encryption method e.g. MD5 or sha256.

This approach is implemented via the `Encrypter` methods (which uses the `openssl::sha256` implementation by default):

    name_pipe <- starwars |>
      add_encrypt(name, hash_key = "hash123", seed="seed456")

    apply_deident(starwars, name_pipe)
