/**
 * 4.2.1.3.  Key Usage
 *    The key usage extension defines the purpose (e.g., encipherment,
 *    signature, certificate signing) of the key contained in the
 *    certificate.  The usage restriction might be employed when a key that
 *    could be used for more than one operation is to be restricted.  For
 *    example, when an RSA key should be used only to verify signatures on
 *    objects other than public key certificates and CRLs, the
 *    digitalSignature and/or nonRepudiation bits would be asserted.
 *    Likewise, when an RSA key should be used only for key management, the
 *    keyEncipherment bit would be asserted.
