```{r, include = FALSE}
knitr::opts_chunk$set(
  collapse = TRUE,
  comment = "#>"
)
```

```{r setup}
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):

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

apply_deident(starwars, name_pipe)
```
