cipherBrute.pl – Bruteforce supported SSL/TLS cipher suites and extract SSL Certificate information.
cipherBrute.pl is a Bruteforce supported SSL/TLS cipher suites and extract useful SSL Certificate information.
Note: This tool uses the installed version of OpenSSL on the machine from which it is run as a basis for determining which cipher suites to test. This tool performs a full handshake in order to determine whether a cipher suite is supported much in the same way as the Nmap ssl-enum-ciphers script.
Note: This tool will work perfectly when run from Kali, but requires one Perl module to be installed (Crypt::X509). To install Crypt::X509 run the following command: cpanm install Crypt::X509
Why…?
+ To quickly determine the supported SSL/TLS cipher suites and present results in a clear/concise manner
+ To quickly extract useful information from SSL Certificates and present results in a clear/concise manner.
How to use
To check what SSL/TLS cipher suites are supported :
|
1 |
perl cipherBrute.pl -f lisofipsorhostnames.txt |
Example usage
To help demonstrate how this tool works and what it is useful for follow these steps:
1 – Create a text file called listofipsorhostnames.txt using your favourite editor (vi/pico/nano).
2 – Copy and paste the following sample data into the new text file:
|
1 2 3 4 5 |
www.yourdomaintotest.com www.yourdomaintotest.com:443 test.idontexist.com iptotest.iptotest.iptotest.iptotest maps.yourdomaintotest.org.uk:4444 |
3 – Run the following command and select option 1 at the menu:
|
1 |
perl cipherBrute.pl -f lisofipsorhostnames.txt |
4 – Alternatively, to extract useful SSL Certificate information (eg Valid from, Expires on…) run the following command and select option 2 at the menu:
|
1 |
perl cipherBrute.pl -f lisofipsorhostnames.txt |
