ECDHE support patch by Adrian Kotelba
2011-07-20 23:42:40 +08:00
#define NGX_DEFAULT_CIPHERS "HIGH:!aNULL:!MD5"
SSL: support for multiple curves (ticket #885). OpenSSL 1.0.2+ allows configuring a curve list instead of a single curve previously supported. This allows use of different curves depending on what client supports (as available via the elliptic_curves extension), and also allows use of different curves in an ECDHE key exchange and in the ECDSA certificate. The special value "auto" was introduced (now the default for ssl_ecdh_curve), which means "use an internal list of curves as available in the OpenSSL library used". For versions prior to OpenSSL 1.0.2 it maps to "prime256v1" as previously used. The default in 1.0.2b+ prefers prime256v1 as well (and X25519 in OpenSSL 1.1.0+). As client vs. server preference of curves is controlled by the same option as used for ciphers (SSL_OP_CIPHER_SERVER_PREFERENCE), the ssl_prefer_server_ciphers directive now controls both.

OCSP stapling: loading OCSP responses. This includes the ssl_stapling_responder directive (defaults to OCSP responder set in certificate's AIA extension). OCSP response for a given certificate is requested once we get at least one connection with certificate_status extension in ClientHello, and certificate status won't be sent in the connection in question. This due to limitations in the OpenSSL API (certificate status callback is blocking). Note: SSL_CTX_use_certificate_chain_file() was reimplemented as it doesn't allow to access the certificate loaded via SSL_CTX.

SSL: the "ssl_verify_client" directive parameter "optional_no_ca". This parameter allows to don't require certificate to be signed by a trusted CA, e.g. if CA certificate isn't known in advance, like in WebID protocol. Note that it doesn't add any security unless the certificate is actually checked to be trusted by some external means (e.g. by a backend). Patch by Mike Kazantsev, Eric O'Connor.

OCSP stapling: ssl_trusted_certificate directive. The directive allows to specify additional trusted Certificate Authority certificates to be used during certificate verification. In contrast to ssl_client_certificate DNs of these cerificates aren't sent to a client during handshake. Trusted certificates are loaded regardless of the fact whether client certificates verification is enabled as the same certificates will be used for OCSP stapling, during construction of an OCSP request and for verification of an OCSP response. The same applies to a CRL (which is now always loaded).

SSL: ssl_session_tickets directive. This adds support so it's possible to explicitly disable SSL Session Tickets. In order to have good Forward Secrecy support either the session ticket key has to be reloaded by using nginx' binary upgrade process or using an external key file and reloading the configuration. This directive adds another possibility to have good support by disabling session tickets altogether. If session tickets are enabled and the process lives for a long a time, an attacker can grab the session ticket from the process and use that to decrypt any traffic that occured during the entire lifetime of the process.

OCSP stapling: loading OCSP responses. This includes the ssl_stapling_responder directive (defaults to OCSP responder set in certificate's AIA extension). OCSP response for a given certificate is requested once we get at least one connection with certificate_status extension in ClientHello, and certificate status won't be sent in the connection in question. This due to limitations in the OpenSSL API (certificate status callback is blocking). Note: SSL_CTX_use_certificate_chain_file() was reimplemented as it doesn't allow to access the certificate loaded via SSL_CTX.

OCSP stapling: ssl_stapling_verify directive. OCSP response verification is now switched off by default to simplify configuration, and the ssl_stapling_verify allows to switch it on. Note that for stapling OCSP response verification isn't something required as it will be done by a client anyway. But doing verification on a server allows to mitigate some attack vectors, most notably stop an attacker from presenting some specially crafted data to all site clients.

OCSP stapling: ssl_trusted_certificate directive. The directive allows to specify additional trusted Certificate Authority certificates to be used during certificate verification. In contrast to ssl_client_certificate DNs of these cerificates aren't sent to a client during handshake. Trusted certificates are loaded regardless of the fact whether client certificates verification is enabled as the same certificates will be used for OCSP stapling, during construction of an OCSP request and for verification of an OCSP response. The same applies to a CRL (which is now always loaded).

OCSP stapling: ssl_stapling_file support. Very basic version without any OCSP responder query code, assuming valid DER-encoded OCSP response is present in a ssl_stapling_file configured. Such file might be produced with openssl like this: openssl ocsp -issuer root.crt -cert domain.crt -respout domain.staple \ -url http://ocsp.example.com

* sscf->stapling_file = { 0, NULL };
OCSP stapling: loading OCSP responses. This includes the ssl_stapling_responder directive (defaults to OCSP responder set in certificate's AIA extension). OCSP response for a given certificate is requested once we get at least one connection with certificate_status extension in ClientHello, and certificate status won't be sent in the connection in question. This due to limitations in the OpenSSL API (certificate status callback is blocking). Note: SSL_CTX_use_certificate_chain_file() was reimplemented as it doesn't allow to access the certificate loaded via SSL_CTX.

SSL: ssl_session_tickets directive. This adds support so it's possible to explicitly disable SSL Session Tickets. In order to have good Forward Secrecy support either the session ticket key has to be reloaded by using nginx' binary upgrade process or using an external key file and reloading the configuration. This directive adds another possibility to have good support by disabling session tickets altogether. If session tickets are enabled and the process lives for a long a time, an attacker can grab the session ticket from the process and use that to decrypt any traffic that occured during the entire lifetime of the process.

OCSP stapling: ssl_stapling_verify directive. OCSP response verification is now switched off by default to simplify configuration, and the ssl_stapling_verify allows to switch it on. Note that for stapling OCSP response verification isn't something required as it will be done by a client anyway. But doing verification on a server allows to mitigate some attack vectors, most notably stop an attacker from presenting some specially crafted data to all site clients.

OCSP stapling: ssl_trusted_certificate directive. The directive allows to specify additional trusted Certificate Authority certificates to be used during certificate verification. In contrast to ssl_client_certificate DNs of these cerificates aren't sent to a client during handshake. Trusted certificates are loaded regardless of the fact whether client certificates verification is enabled as the same certificates will be used for OCSP stapling, during construction of an OCSP request and for verification of an OCSP response. The same applies to a CRL (which is now always loaded).

OCSP stapling: ssl_stapling_file support. Very basic version without any OCSP responder query code, assuming valid DER-encoded OCSP response is present in a ssl_stapling_file configured. Such file might be produced with openssl like this: openssl ocsp -issuer root.crt -cert domain.crt -respout domain.staple \ -url http://ocsp.example.com

OCSP stapling: ssl_stapling_verify directive. OCSP response verification is now switched off by default to simplify configuration, and the ssl_stapling_verify allows to switch it on. Note that for stapling OCSP response verification isn't something required as it will be done by a client anyway. But doing verification on a server allows to mitigate some attack vectors, most notably stop an attacker from presenting some specially crafted data to all site clients.

OCSP stapling: loading OCSP responses. This includes the ssl_stapling_responder directive (defaults to OCSP responder set in certificate's AIA extension). OCSP response for a given certificate is requested once we get at least one connection with certificate_status extension in ClientHello, and certificate status won't be sent in the connection in question. This due to limitations in the OpenSSL API (certificate status callback is blocking). Note: SSL_CTX_use_certificate_chain_file() was reimplemented as it doesn't allow to access the certificate loaded via SSL_CTX.

SSL: the "ssl_verify_client" directive parameter "optional_no_ca". This parameter allows to don't require certificate to be signed by a trusted CA, e.g. if CA certificate isn't known in advance, like in WebID protocol. Note that it doesn't add any security unless the certificate is actually checked to be trusted by some external means (e.g. by a backend). Patch by Mike Kazantsev, Eric O'Connor.

OCSP stapling: ssl_trusted_certificate directive. The directive allows to specify additional trusted Certificate Authority certificates to be used during certificate verification. In contrast to ssl_client_certificate DNs of these cerificates aren't sent to a client during handshake. Trusted certificates are loaded regardless of the fact whether client certificates verification is enabled as the same certificates will be used for OCSP stapling, during construction of an OCSP request and for verification of an OCSP response. The same applies to a CRL (which is now always loaded).

SSL: ssl_session_tickets directive. This adds support so it's possible to explicitly disable SSL Session Tickets. In order to have good Forward Secrecy support either the session ticket key has to be reloaded by using nginx' binary upgrade process or using an external key file and reloading the configuration. This directive adds another possibility to have good support by disabling session tickets altogether. If session tickets are enabled and the process lives for a long a time, an attacker can grab the session ticket from the process and use that to decrypt any traffic that occured during the entire lifetime of the process.

OCSP stapling: loading OCSP responses. This includes the ssl_stapling_responder directive (defaults to OCSP responder set in certificate's AIA extension). OCSP response for a given certificate is requested once we get at least one connection with certificate_status extension in ClientHello, and certificate status won't be sent in the connection in question. This due to limitations in the OpenSSL API (certificate status callback is blocking). Note: SSL_CTX_use_certificate_chain_file() was reimplemented as it doesn't allow to access the certificate loaded via SSL_CTX.

OCSP stapling: ssl_stapling_verify directive. OCSP response verification is now switched off by default to simplify configuration, and the ssl_stapling_verify allows to switch it on. Note that for stapling OCSP response verification isn't something required as it will be done by a client anyway. But doing verification on a server allows to mitigate some attack vectors, most notably stop an attacker from presenting some specially crafted data to all site clients.
