ba4defb707 Merge pull request #14 from tomato42/scan-improvements-02 
Improve scanning performance and reduce false negatives

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 
Basically all Google servers support Chacha20 now and it is
not a bad choice, so report it as a regular cipher

2b794ebfe0 fix and extend reporting of AES-GCM ciphers 
AES-GCM ciphers don't have "AES-GCM" substring in the openssl name

extend reporting of AES ciphers, split to AES-CBC, AES-GCM and
AES in general

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.

ff620f5b26 report number of servers that use ECDSA and RSA certificates 
Since use of both ECDSA and RSA certificates is easy, it is
relatively simple to support both. Report the total number of
such servers

b6b9a1a364 Improve scanning performance and reduce false negatives 
scan all the machines from top-1m.csv file, wait for completion
of all jobs

i=1 is an off-by-one-error

support top-1m.csv files with arbitrary number of sites

run scans for many hosts at a time, but don't run more than
specified amount

in case where default domain name doesn't resolve or doesn't have
port 443 open, retry with www. prefix

4e0e03b61e make default output more narrow 
If server uses the same certificate for all connections, it's
useless to print the same information over and over.

In such case, omit those columns and print a summary at the end

ac3e5f4d62 Correctly report TLSv1.2 only ciphers as negotiable with TLSv1.2 
Previously scan would report:
prio  ciphersuite                  protocols                    pfs_keysize
1     ECDHE-RSA-AES128-GCM-SHA256  SSLv3,TLSv1,TLSv1.1,TLSv1.2  ECDH,P-256,256bits
2     ECDHE-RSA-RC4-SHA            SSLv3,TLSv1,TLSv1.1,TLSv1.2  ECDH,P-256,256bits

Now it correctly reports:
prio  ciphersuite                  protocols                    pfs_keysize
1     ECDHE-RSA-AES128-GCM-SHA256  TLSv1.2                      ECDH,P-256,256bits
