## Quick Start

### Prerequisites

 * either HC4 Credentials or HC5 Credentials.
 *
 * <p>This class provides a library-independent way to configure
 * authentication credentials that work with both Apache HttpComponents 4.x
 * and 5.x clients.</p>
 *
 * <p>Example usage:</p>
 * <pre>{@code
 * CredentialsConfig config = new CredentialsConfig();
 * config.setUsername("user");
 * config.setPassword("secret");
 *

 * either HC4 Hc4Authentication or HC5 Hc5Authentication.
 *
 * <p>This class provides a library-independent way to configure
 * HTTP authentication that works with both Apache HttpComponents 4.x
 * and 5.x clients.</p>
 *
 * <p>Example usage for Basic authentication:</p>
 * <pre>{@code
 * WebAuthenticationConfig config = new WebAuthenticationConfig();
 * config.setHost("example.com");
