Hubert Kario 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
 2014-04-19 23:14:57 +02:00
Hubert Kario 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
 2014-04-19 23:14:57 +02:00
Hubert Kario fd6fcdd359 fix spelling in TLS stats (TLS1_1 vs TLS1.1) 2014-04-19 23:14:57 +02:00
Hubert Kario 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.
 2014-04-19 23:14:47 +02:00
Hubert Kario 45dc1da3f6 add ability to ignore results from untrusted servers 2014-04-19 23:07:01 +02:00
Hubert Kario 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

Hubert Kario 863441a179 parsing of signature algorithm and key size 
add parsing of signature algorithm and key size from the individual
results, report summary
 2014-04-19 23:07:00 +02:00
Hubert Kario 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

Julien Vehent f703ca9c26 Merge pull request #12 from tomato42/certificate-scanning-02 
Certificate scanning 02 (alternative version)
 2014-04-19 11:46:25 -04:00
Hubert Kario 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

Hubert Kario 9931ca2a2d update README with new examples 
New features = new examples

Hubert Kario f04567d40e check if certificate used by server is trused 
Use system trust anchors to check if certificate chain used by server
is actually valid.

Hubert Kario 946cc6a9ac Report the signature type used on server certificate 
Parse the certificate used by server and report the signature used:

Hubert Kario 32eba4e644 update examples from README

to illustrate that

Hubert Kario 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
