/**

 *
 * <pre>
 * Replaces an identifier with a surrogate using Format Preserving Encryption
 * (FPE) with the FFX mode of operation; however when used in the
 * `ReidentifyContent` API method, it serves the opposite function by reversing
 * the surrogate back into the original identifier. The identifier must be
 * encoded as ASCII. For a given crypto key and context, the same identifier
 * will be replaced with the same surrogate. Identifiers must be at least two
 * characters long. In the case that the identifier is the empty string, it will
 * be skipped. See https://cloud.google.com/dlp/docs/pseudonymization to learn
 * more.
 * Note: We recommend using  CryptoDeterministicConfig for all use cases which
 * do not require preserving the input alphabet space and size, plus warrant
 * referential integrity.

     * Therefore, choose your custom infoType name carefully after considering
     * what your data looks like. One way to select a name that has a high chance
     * of yielding reliable detection is to include one or more unicode characters
