In order to present info to the user, QSslCipher lets you see things like
the cipher, key length, key exchange method etc. etc. however in SSL these
are all bundled together as a cipher suite - this is just a 16 bit number
(24 bits in SSLv2). What we'd ideally do is just store the number and then
look up the other info as needed. Ideally we'd just query the openssl in
use for the list of available ciphers which we could store as a list/vector
globally. Unfortunately openssl doesn't provide any API for looking up the
info given the id (though i've at least partially got this addressed in
openssl 1.1). At the moment the code has to do some horrendous parsing of a
