54ec2aca99 fix: ignore case in bash version string 
Currently on some systems `bash --version` reports `GNU bash, Version 4[…]` which will fail the test.

Cipherscan fixes, speedups and saving of certificates (v3)
 2014-11-05 12:36:33 -05:00
Hubert Kario
c4a8495a54 limit number of forks needed to speed up execution 
bash has a built in regular expression processor, we can match
lines using =~

moreover, stuff that will match while being inside parentheses is
later available in the BASH_REMATCH array

the IFS (Internal Field Separator) by default includes space, tab and
new line, as such we can use it to split longer lines to separate
words, just as awk '{print $1}' can, just need to put the value to
an array for that

we also don't have to use $(echo $var) when assigning variables, $var
is enough

bash has also built in substitution engine, so we can do ${var/,/ & }
to switch all commas to ampersands when using the variable
 2014-11-05 18:14:30 +01:00
Hubert Kario
9f06829486 make handling of self signed certs more robust 
openssl sometimes will print the filename, then the error, and finish
with OK, matching the colon and space prevents from considering such
certs to be valid
 2014-11-05 18:13:39 +01:00
Hubert Kario
4c22d50f0c few less forks in the script 
again, we can use arrays and a bit advanced awk syntax to reduce
the number of forks necessary to run the script
 2014-11-05 18:13:39 +01:00
Hubert Kario
0f576c1fbc don't calculate sha sums for the certificates over and over 
we can use cksum to calculate simple checksum much faster than
with using openssl, so we can compute sums only once
 2014-11-05 18:13:39 +01:00
Hubert Kario
1eae0cc71b use CApath for certificates and store certificates (v2) 
CApath is about 20% faster than CAfile so use it, also
save the received certificates from the servers for later analysis
(proper hostname checking, looking for certificates sharing private key,
etc.)

Use the mechanism from cipherscan to find location of ca cert bundle
 2014-11-05 18:13:39 +01:00
Hubert Kario
d9b718be12 clean up the extracted certificate 
the certificate extracted in the above way will contain some junk
from openssl s_client output we don't want like verification status
we can remove it ro reduce disk usage for saved certificates
 2014-11-05 18:13:39 +01:00
Hubert Kario
3e37517c96 add ability to also save leaf certificates and untrusted ones 2014-11-05 18:13:39 +01:00
Hubert Kario
826f7b5541 add caching of intermediate CA certificates 2014-11-05 18:13:39 +01:00
Hubert Kario
3b14cd914f no need to grep the input when we're using awk (v2) 
awk has an inbuilt version of grep, also truncate processing as soon
as we find what we're looking for

This version uses slightly different syntax that is compatible with old
awk

Fix delay option
 2014-10-29 17:34:18 -04:00
Hubert Kario
11ce6187de small fixes for delay 
firstly, test_cipher_on_target() will try at least 4 connections before
incurring the sleep, for aggressive rate limiter on server side it may be
too much, so sleep before every connection

secondly, because running external commands like sleep incurs a fork
penalty, we first check if it is necessary
 2014-10-28 16:44:43 +01:00
Hubert Kario
71ba3c88b0 increase timeout 
when some servers notice a scan (because of frequent connections) they
delay further connections, increase the timeout to properly scan them

af2e25ec89 fix EDH checking
