a71bfe5ebd detect some TLS intolerancies
buggy servers may choke on large ClientHello's, TLSv1.2 ClientHello's,
etc. try to detect such failures and report them

among tried connections are TLS1.2, TLS1.1, TLS1.0 and SSLv3 with
ability to downgrade to lower protocol versions as well as a size
limited client hello, both TLS1.2 and TLS1.0 version

341f657e83 better detection for EXP and low grade ciphers in stats
EXP is self explanatory - export grade
DES-CBC3-MD5 is available only in SSLv2 - not secure
RC4-64-MD5 is also a weakened version (though not marked as export grade)

c52e008347 add support for testing supported curves
since early versions of 1.0.2 openssl supports -curves command line
option, it allows us to set the curves advertised as supported

use the same approach to testing: advertise all, check what server
accepts, remove the accepted from list, repeat. When server aborts
connection or selects non ECC cipher, we know that we've tested all.

af2e25ec89 fix EDH checking
old ciphers have names that use EDH instead of DHE so we need check

76d791fcbe make cipher selection simulation generic
it's relatively easy to make the cipher selection generic,
so that adding different clients is as easy as converting their
client hello cipher ordering to openssl cipher names

c82bc44558 report cipher ordering in scanning stats, use it to simulate handshakes
since now we know if server honours client order or not, we can use it
to properly simulate handshakes for a given client, also report
the general stats of this server configuration variable

142726c4fd count ECDH-RSA ciphers as ECDSA
the ECDH parameters come from server certificate - the point
on elliptic curve. The RSA comes from the signature on the certificate
which comes from CA

separately, do a total count of servers that support broken and insecure
ciphers

686d7c958b extend reporting of RC4-related stats
While preferring RC4 in TLS1.0 or SSL3 was recommended before,
it was always known that TLS1.1 and TLS1.2 were not vulnerable against
BEAST, so forcing RC4 there is a mistake. Report number of such servers.

21bba67df0 extend SSL stats
Two interesting server configurations are ones that support
only SSL3 or TLS1 only (old, but otherwise correctly configured servers)
and ones that support only TLS1.1 or up (brave admins that support
only new clients)

349d4ebc3c more detailed PFS report
Just because server supports some bad DH params, doesn't mean
it will force them on users. Report number of servers
that prefer specific DH params.

d3b6f9b507 fix reporting of the TLS1.2 but not TLS1.1
Some servers may be configured to support only TLS1.2, it would
count them towards the number of servers affected by the OpenSSL bug

c8abfb53e8 add support for Chacha20 based ciphers

faef8d692f in "no-untrusted mode": filter out ADH and AECDH suites
If server negotiates ADH or AECDH suite, openssl returns "ok" in
cert checking. Don't mark server as trusted because of that.

Don't collect statistics on servers that provide only untrusted
connections.
