 // SECURITY WARNING

 // Using self-signed certificates has the following security risks:
 // 1. Encryption without authentication and thus vulnerable to
 //    man-in-the-middle attacks.
 // 2. Self-signed certificates cannot be revoked.
 //
 // Use this certificate only after the above risks are acknowledged.
