00b20a20ed perform SNI enabled scan 
for example, youtube requires SNI extension to be present to return
ECDSA certificates, use it for scanning

5dfa3c444e put ECDSA ciphers before RSA ciphers 
Google servers (like youtube) negotiate ECDSA variant
of ciphersuite only if the RSA variant is also present,
so to return more comple cipher listing, we need to move
ECDSA ciphers before RSA ciphers

8817a7b1c8 testtop1m.sh: correct counting of background jobs 
`jobs` command returns multiple lines for a jobs with `if` so counting
number of background jobs was off

92851d7c74 Merge pull request #17 from tomato42/proper-quit 
use proper quit semantic for openssl s_client

dca614d218 use proper quit semantic for openssl s_client 
openssl s_client expect "Q" as the first character on a line,
with case being significant. Also, the \n marker is unnecessary
the echo command prints a newline automatically, additionally,
for the \n to be actually interpreted, the -e option must be used

d7b99f125e restore timeout 
some servers have port 443 open but won't reply to ClientHello
requests, this hangs openssl s_client, as such we need to kill it
after some timeout

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 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.

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

1     ECDHE-RSA-AES128-GCM-SHA256  TLSv1.2                      ECDH,P-256,256bits
