b3eb0ac67b Updated cipherscan to handle environmental error conditions better: 
1. If bundled openssl is a bad binary (e.g. wrong glibc), use system openssl
 2. Skip bundled openssl.cnf if it causes failures (e.g. openssl w/o GOST)

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)

8bde9c4d03 do fallback scan in case of problems 
It's unlikely that there are SSLv2 only servers on the 'net, all
that were detected as such and I've checked actually are intolerant
to low placement of RC4 in cipher order or intolerant to large client
hello in general. In case we detect issues with the server, switch to
reduced cipher set and run the test again that should give better results
for about 3% of hosts

224227cc5e force at least TLSv1.0 in curves tolerance test 
because to advertise curves to server we need extensions and
extensions are only available in TLSv1.0 or later, we need to force
OpenSSL not to send SSLv2 compatible hello if it thinks it's ok to
do (when there are SSLv2 ciphers present in cipherstring it will try to)
 2015-03-27 10:04:15 -04:00
Hubert Kario
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.
