the class SignatureVerifierImpl method doVerifyInternal.

/**
 * Given a request and response, analyze the request Authorization header and
 * look up the appropriate key in the keystore; if the
 * header is missing, incomplete or invalid, will send a 401 error on the response
 * with WWW-Authenticate header and return null.
 *
 * If the request contains a Digest header, the returned HttpServletRequest
 * will wrap the original with one that will lazily verify the request body.
 * Consumers should replace the original ServletRequest with the returned one
 * for further processing, and be prepared for the possible VerificationException
 *
 * @param request
 * @throws IOException
 * @throws GeneralSecurityException
