## Interface JDBCAuth

- All Superinterfaces:
    AuthenticationProvider, AuthProvider

  Deprecated.
  This class has been replaced by the class `JDBCAuthentication` for authentication and `JDBCAuthorization` for authorization

      public interface JDBCAuth
      extends AuthProvider

  Factory interface for creating `AuthenticationProvider` instances that use the Vert.x JDBC client. By default the hashing strategy is SHA-512. If you're already running in production this is backwards compatible, however for new deployments or security upgrades it is recommended to use the PBKDF2 strategy as it is the current OWASP recommendation for password storage.

      Provide a application configuration level on hash nonce's as a ordered list of nonces where each position corresponds to a version.

Leaving the attacker only with the brute force approach. The implementation relays to the JDBCHashStrategy provided.
      Parameters:
        `nonces` - a List of non null Strings.
