docs: Gets the OCSP responses. These responses are used to determine
  the revocation status of the specified certificates when OCSP is used.
  
  @return a map of OCSP responses. Each key is an
  {@code X509Certificate} that maps to the corresponding
  DER-encoded OCSP response for that certificate. A deep copy of
  the map is returned to protect against subsequent modification.
  Returns an empty map if no responses have been specified.
