测试ssl/tls版本支持时openssl实现的差异
我正在尝试使用测试ssl/tls版本支持时openssl实现的差异,openssl,Openssl,我正在尝试使用openssl测试tls/ssl版本支持。我看到3个不同版本的OpenSSL的结果有所不同 OpenSSL 1.0.1j 2014年10月15日：请注意，在这种情况下，我可以使用OpenSSL建立连接，甚至可以测试ssl2、tls1等。但以下输出仅在尝试测试ssl3时出现。所以，我无法理解这种行为 C:\Users\himanshu.agrawal>openssl s_client -connect facebook.com:443 -ssl3 WARNING: can't
opensslC:\Users\himanshu.agrawal>openssl s_client -connect facebook.com:443 -ssl3
WARNING: can't open config file: /apache24/conf/openssl.cnf
unknown option -ssl3
usage: s_client args
-host host - use -connect instead
-port port - use -connect instead
-connect host:port - who to connect to (default is localhost:4433)
-verify arg - turn on peer certificate verification
-verify_return_error - return verification errors
-cert arg - certificate file to use, PEM format assumed
-certform arg - certificate format (PEM or DER) PEM default
-key arg - Private key file to use, in cert file if
not specified but cert file is.
-keyform arg - key format (PEM or DER) PEM default
-pass arg - private key file pass phrase source
-CApath arg - PEM format directory of CA's
-CAfile arg - PEM format file of CA's
-reconnect - Drop and re-make the connection with the same Session-ID
-pause - sleep(1) after each read(2) and write(2) system call
-prexit - print session information even on connection failure
-showcerts - show all certificates in the chain
-debug - extra output
-msg - Show protocol messages
-nbio_test - more ssl protocol testing
-state - print the 'ssl' states
-nbio - Run with non-blocking IO
-crlf - convert LF from terminal into CRLF
-quiet - no s_client output
-ign_eof - ignore input eof (default when -quiet)
-no_ign_eof - don't ignore input eof
-psk_identity arg - PSK identity
-psk arg - PSK in hex (without 0x)
-srpuser user - SRP authentification for 'user'
-srppass arg - password for 'user'
-srp_lateuser - SRP username into second ClientHello message
-srp_moregroups - Tolerate other than the known g N values.
-srp_strength int - minimal mength in bits for N (default 1024).
-ssl2 - just use SSLv2
-ssl3 - just use SSLv3
-tls1_2 - just use TLSv1.2
-tls1_1 - just use TLSv1.1
-tls1 - just use TLSv1
-dtls1 - just use DTLSv1
-fallback_scsv - send TLS_FALLBACK_SCSV
-mtu - set the link layer MTU
-no_tls1_2/-no_tls1_1/-no_tls1/-no_ssl3/-no_ssl2 - turn off that protocol
-bugs - Switch on all SSL implementation bug workarounds
-serverpref - Use server's cipher preferences (only SSLv2)
-cipher - preferred cipher to use, use the 'openssl ciphers'
command to see what is available
-starttls prot - use the STARTTLS command before starting TLS
for those protocols that support it, where
'prot' defines which one to assume. Currently,
only "smtp", "pop3", "imap", "ftp" and "xmpp"
are supported.
-engine id - Initialise and use the specified engine
-rand file;file;...
-sess_out arg - file to write SSL session to
-sess_in arg - file to read SSL session from
-servername host - Set TLS extension servername in ClientHello
-tlsextdebug - hex dump of all TLS extensions received
-status - request certificate status from server
-no_ticket - disable use of RFC4507bis session tickets
-nextprotoneg arg - enable NPN extension, considering named protocols supported (comma-separated list)
-legacy_renegotiation - enable use of legacy renegotiation (dangerous)
-use_srtp profiles - Offer SRTP key management with a colon-separated profile list
-keymatexport label - Export keying material using label
-keymatexportlen len - Export len bytes of keying material (default 20)

任何人都知道或看到了这些差异，尤其是前2个。您的第一个测试无法连接，因为它不支持ssl3。未知选项-ssl3Stack Overflow是一个解决编程和开发问题的网站。这个问题似乎离题了，因为它与编程或开发无关。请参见帮助中心中的。也许或者会是一个更好的提问的地方。此外，SSLv3在测试后被所有人有效关闭。使用
