 It appears to me that the TLS configurations and ciphers used on several
 Torproject websites are in desperate need of someone love and attention.

 For instance the main website, https://www.torproject.org/ is only
 accessible using the old TLSv1.0 not the currently recommended TLSv1.2
 (nor the upcoming TLSv1.3). Further more it is not only the protocol
 versions which are in need of some attention, the ciphers used include
 also need some improvements. For instance RC4 is used in spite of RFC7465,
 (apparently also MD5 is used).

 If someone site admin where to have a look at it but needs some help along
 the way the Mozilla Foundation have created a recommended list of ciphers
 and protocols which can be used as a sort of "best common  practise" for
 HTTPS configuration. And Qaulys ssllabs provide a quick and easy tool to
 test how it would be handled by various browsers and versions (along with
 some extra tests).
