2016-11-24proxy: Support HTTPS proxy and SOCKS+HTTP(s)Alex Rousskov
* HTTPS proxies: An HTTPS proxy receives all transactions over an SSL/TLS connection. Once a secure connection with the proxy is established, the user agent uses the proxy as usual, including sending CONNECT requests to instruct the proxy to establish a [usually secure] TCP tunnel with an origin server. HTTPS proxies protect nearly all aspects of user-proxy communications as opposed to HTTP proxies that receive all requests (including CONNECT requests) in vulnerable clear text. With HTTPS proxies, it is possible to have two concurrent _nested_ SSL/TLS sessions: the "outer" one between the user agent and the proxy and the "inner" one between the user agent and the origin server (through the proxy). This change adds supports for such nested sessions as well. A secure connection with a proxy requires its own set of the usual SSL options (their actual descriptions differ and need polishing, see TODO): --proxy-cacert FILE CA certificate to verify peer against --proxy-capath DIR CA directory to verify peer against --proxy-cert CERT[:PASSWD] Client certificate file and password --proxy-cert-type TYPE Certificate file type (DER/PEM/ENG) --proxy-ciphers LIST SSL ciphers to use --proxy-crlfile FILE Get a CRL list in PEM format from the file --proxy-insecure Allow connections to proxies with bad certs --proxy-key KEY Private key file name --proxy-key-type TYPE Private key file type (DER/PEM/ENG) --proxy-pass PASS Pass phrase for the private key --proxy-ssl-allow-beast Allow security flaw to improve interop --proxy-sslv2 Use SSLv2 --proxy-sslv3 Use SSLv3 --proxy-tlsv1 Use TLSv1 --proxy-tlsuser USER TLS username --proxy-tlspassword STRING TLS password --proxy-tlsauthtype STRING TLS authentication type (default SRP) All --proxy-foo options are independent from their --foo counterparts, except --proxy-crlfile which defaults to --crlfile and --proxy-capath which defaults to --capath. Curl now also supports %{proxy_ssl_verify_result} --write-out variable, similar to the existing %{ssl_verify_result} variable. Supported backends: OpenSSL, GnuTLS, and NSS. * A SOCKS proxy + HTTP/HTTPS proxy combination: If both --socks* and --proxy options are given, Curl first connects to the SOCKS proxy and then connects (through SOCKS) to the HTTP or HTTPS proxy. TODO: Update documentation for the new APIs and --proxy-* options. Look for "Added in 7.XXX" marks.

to make it obvious to users trying to use the feature with TLS backends not supporting it. Discussed in #781 Reported-by: Travis Burtrum

2015-01-17vtls: Removed unimplemented overrides of curlssl_close_all()Steve Holme
Carrying on from commit 037cd0d991, removed the following unimplemented instances of curlssl_close_all(): Curl_axtls_close_all() Curl_darwinssl_close_all() Curl_cyassl_close_all() Curl_gskit_close_all() Curl_gtls_close_all() Curl_nss_close_all() Curl_polarssl_close_all()
2015-01-17vtls: Separate the SSL backend definition from the API setupSteve Holme
Slight code cleanup as the SSL backend #define is mixed up with the API function setup.
2015-01-16copyright years: after OCSP stapling changesDaniel Stenberg
2015-01-16gtls: add support for the Certificate Status Request TLS extensionAlessandro Ghedini
Also known as "status_request" or OCSP stapling, defined in RFC6066 section 8. This requires GnuTLS 3.1.3 or higher to build, however it's recommended to use at least GnuTLS 3.3.11 since previous versions had a bug that caused the OCSP response verfication to fail even on valid responses.
2014-12-30vtls: Use '(void) arg' for unused parametersSteve Holme
Prefer void for unused parameters, rather than assigning an argument to itself as a) unintelligent compilers won't optimize it out, b) it can't be used for const parameters, c) it will cause compilation warnings for clang with -Wself-assign and d) is inconsistent with other areas of the curl source code.

2014-07-31ssl: generalize how the ssl backend identifier is setDaniel Stenberg
Each backend now defines CURL_SSL_BACKEND accordingly. Added the *AXTLS one which was missing previously.
2014-07-30vtls: make the random function mandatory in the TLS backendDaniel Stenberg
To force each backend implementation to really attempt to provide proper random. If a proper random function is missing, then we can explicitly make use of the default one we use when TLS support is missing. This commit makes sure it works for darwinssl, gnutls, nss and openssl.
