Good job with those tests and good luck with the real site!

First, I did a quick SSLLabs scan on the server. That told me that "sslEnabledProtocols" in an SSLHostConfig was indeed wrong. And it told me that all simulated Chrome handshakes failed, but most other simulated handshakes were fine. Then (directly violating the "change only one variable at a time" principle) I set it back to "protocols," *and* cut out the cipher list entirely. That worked just fine. The weird part is that so far as I can tell, the cipher list looks *exactly* like the cipher list in the original Java Keystore version of the connector I compared the cipher lists given in the SSLLabs reports for three cases: the new connector with the old cipher list, the new connector with no cipher list at all, and (using the live version of the server) the old connector with the old cipher list, and the results were remarkable: test, no cipher list TLS_ECDH_ECDSA_WITH_AES_128_CBC_SHA (0xc004) WEAK 128 TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA (0xc009) ECDH secp521r1 (eq. 15360 bits RSA) FS WEAK 128 TLS_ECDH_RSA_WITH_AES_128_CBC_SHA (0xc00e) WEAK 128 TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256 (0xc023) ECDH secp521r1 (eq. 15360 bits RSA) FS WEAK 128 TLS_ECDH_ECDSA_WITH_AES_128_CBC_SHA256 (0xc025) WEAK 128 TLS_ECDH_RSA_WITH_AES_128_CBC_SHA256 (0xc029) WEAK 128 TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256 (0xc02b) ECDH secp521r1 (eq. 15360 bits RSA) FS 128 TLS_ECDH_ECDSA_WITH_AES_128_GCM_SHA256 (0xc02d) 128 TLS_ECDH_RSA_WITH_AES_128_GCM_SHA256 (0xc031) 128 TLS_ECDH_ECDSA_WITH_AES_256_CBC_SHA (0xc005) WEAK 256 TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA (0xc00a) ECDH secp521r1 (eq. 15360 bits RSA) FS WEAK 256 TLS_ECDH_RSA_WITH_AES_256_CBC_SHA (0xc00f) WEAK 256 TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384 (0xc024) ECDH secp521r1 (eq. 15360 bits RSA) FS WEAK 256 TLS_ECDH_ECDSA_WITH_AES_256_CBC_SHA384 (0xc026) WEAK 256 TLS_ECDH_RSA_WITH_AES_256_CBC_SHA384 (0xc02a) WEAK 256 TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384 (0xc02c) ECDH secp521r1 (eq. 15360 bits RSA) FS 256 TLS_ECDH_ECDSA_WITH_AES_256_GCM_SHA384 (0xc02e) 256 TLS_ECDH_RSA_WITH_AES_256_GCM_SHA384 (0xc032) 256 test, with old cipher list TLS_ECDH_ECDSA_WITH_AES_128_CBC_SHA (0xc004) WEAK 128 TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA (0xc009) ECDH secp521r1 (eq. 15360 bits RSA) FS WEAK 128 TLS_ECDH_RSA_WITH_AES_128_CBC_SHA (0xc00e) WEAK 128 TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256 (0xc023) ECDH secp521r1 (eq. 15360 bits RSA) FS WEAK 128 TLS_ECDH_ECDSA_WITH_AES_128_CBC_SHA256 (0xc025) WEAK 128 TLS_ECDH_RSA_WITH_AES_128_CBC_SHA256 (0xc029) WEAK 128 TLS_ECDH_ECDSA_WITH_AES_256_CBC_SHA (0xc005) WEAK 256 TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA (0xc00a) ECDH secp521r1 (eq. 15360 bits RSA) FS WEAK 256 TLS_ECDH_RSA_WITH_AES_256_CBC_SHA (0xc00f) WEAK 256 TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384 (0xc024) ECDH secp521r1 (eq. 15360 bits RSA) FS WEAK 256 TLS_ECDH_ECDSA_WITH_AES_256_CBC_SHA384 (0xc026) WEAK 256 TLS_ECDH_RSA_WITH_AES_256_CBC_SHA384 (0xc02a) WEAK 256 original connector, with old cipher list TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA (0xc013) ECDH secp521r1 (eq. 15360 bits RSA) FS WEAK 128 TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256 (0xc027) ECDH secp521r1 (eq. 15360 bits RSA) FS WEAK 128 TLS_RSA_WITH_AES_256_CBC_SHA (0x35) WEAK 256 TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA (0xc014) ECDH secp521r1 (eq. 15360 bits RSA) FS WEAK 256 TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 (0xc028) ECDH secp521r1 (eq. 15360 bits RSA) FS WEAK 256 The test with no cipher list produced (I think) five matches with your "acceptable" list, two of which were also on your "ideal" list. The test with the old cipher list on the new connector produced only 12 of the 18 on the "no cipher list" test, none of which were on either of your lists. And the original connector produced what appears to be a completely different list in the report, with nothing in common with the other two, or with your lists, and yet it is TLS 1.2-only, and it seems to get along just fine with Chrome. This is very weird. But at least we have the test working. The next step is to see if we can get the real site working. -- JHHL --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
