We respect your privacy and want you to be able to choose to be anonymous if you so choose. So most of our services have corresponding Tor .onion sites.
Note that the certificate used for these sites is the same as the one used for clearnet ~vern sites, so the browser will issue an SSL_ERROR_BAD_CERT_DOMAIN error, meaning that the domain you are connecting to and the domain defined by the certificate are not the same. Click "Advanced..." then click "Accept the Risk and Continue" to visit them.
Currently, only two certificate authorities provide certificates for .onion domains, neither of which being Let's Encrypt, so it will take a while for us to get fifteen of them.
