CipherScan ========== A very simple way to find out which SSL ciphersuites are supported by a target. Run: ./cipherscan www.google.com:443 And watch. The newer your version of openssl, the better results you'll get. Older versions of OpenSSL don't support TLS1.2 ciphers, elliptic curves, etc... Build Your Own! Options ------- Enable benchmarking by setting DOBENCHMARK to 1 at the top of the script. You can use one of the options below (only one. yes, I know...) Use '-v' to get more stuff to read. Use '-a' to force openssl to test every single cipher it know. Use '-json' to output the results in json format ``` $ ./cipherscan -json www.google.com:443 ``` Example ------- ``` $ ./cipherscan www.google.com:443 ................... prio ciphersuite protocols pfs_keysize 1 ECDHE-RSA-CHACHA20-POLY1305 SSLv3,TLSv1,TLSv1.1,TLSv1.2 ECDH,P-256,256bits 2 ECDHE-RSA-AES128-GCM-SHA256 SSLv3,TLSv1,TLSv1.1,TLSv1.2 ECDH,P-256,256bits 3 ECDHE-RSA-RC4-SHA SSLv3,TLSv1,TLSv1.1,TLSv1.2 ECDH,P-256,256bits 4 ECDHE-RSA-AES128-SHA SSLv3,TLSv1,TLSv1.1,TLSv1.2 ECDH,P-256,256bits 5 AES128-GCM-SHA256 SSLv3,TLSv1,TLSv1.1,TLSv1.2 6 RC4-SHA SSLv3,TLSv1,TLSv1.1,TLSv1.2 7 RC4-MD5 SSLv3,TLSv1,TLSv1.1,TLSv1.2 8 ECDHE-RSA-AES256-GCM-SHA384 SSLv3,TLSv1,TLSv1.1,TLSv1.2 ECDH,P-256,256bits 9 ECDHE-RSA-AES256-SHA384 SSLv3,TLSv1,TLSv1.1,TLSv1.2 ECDH,P-256,256bits 10 ECDHE-RSA-AES256-SHA SSLv3,TLSv1,TLSv1.1,TLSv1.2 ECDH,P-256,256bits 11 AES256-GCM-SHA384 SSLv3,TLSv1,TLSv1.1,TLSv1.2 12 AES256-SHA256 SSLv3,TLSv1,TLSv1.1,TLSv1.2 13 AES256-SHA SSLv3,TLSv1,TLSv1.1,TLSv1.2 14 ECDHE-RSA-DES-CBC3-SHA SSLv3,TLSv1,TLSv1.1,TLSv1.2 ECDH,P-256,256bits 15 DES-CBC3-SHA SSLv3,TLSv1,TLSv1.1,TLSv1.2 16 ECDHE-RSA-AES128-SHA256 SSLv3,TLSv1,TLSv1.1,TLSv1.2 ECDH,P-256,256bits 17 AES128-SHA256 SSLv3,TLSv1,TLSv1.1,TLSv1.2 18 AES128-SHA SSLv3,TLSv1,TLSv1.1,TLSv1.2 $ ./cipherscan -starttls xmpp jabber.ccc.de:5222 ......... prio ciphersuite protocols pfs_keysize 1 DHE-RSA-AES256-SHA SSLv3,TLSv1 DH,1024bits 2 AES256-SHA SSLv3,TLSv1 3 EDH-RSA-DES-CBC3-SHA SSLv3,TLSv1 DH,1024bits 4 DES-CBC3-SHA SSLv3,TLSv1 5 DHE-RSA-AES128-SHA SSLv3,TLSv1 DH,1024bits 6 AES128-SHA SSLv3,TLSv1 7 RC4-SHA SSLv3,TLSv1 8 RC4-MD5 SSLv3,TLSv1 ```
