// In this example, we map a UUID to another UUID and back using a password.
// This allows us to create UUIDs that are linked in some way and can be used
// to identify the same entity across different systems.

  // Define a list of characters to use for the transformation. Here we use the
  // hexadecimal character list since the input UUID is in hexadecimal format.
  // We can use any character list we like as long as it is unique and contains
  // at least all the characters in the input strings.
  final hexCharList = '0123456789abcdef';

  // Define a seed to use for the transformation. This can be any string.
  // It uses SHA256. Different seeds will produce different transformations.
