The download of Sentinel-1 products from the Sentinel Hubhttps://scihub.esa.int/userguide/BatchScripting is performed without a certificate (which is maybe dangerous in case of an automated systematic download of multiple files, i.e. Man in the middle attack…).
I wonder if there is a certificate that is available to be used when downloading from the Sentinel Hub?
I wonder why they told you that you should report it here. We have nothing to do with the SciHub except both are ESA projects. We can’t provide a certificate for the SciHub.
