2018-09-06x509asn1: return CURLE_PEER_FAILED_VERIFICATION on failure to parse certHan Han
CURLE_PEER_FAILED_VERIFICATION makes more sense because Curl_parseX509 does not allocate memory internally as its first argument is a pointer to the certificate structure. The same error code is also returned by Curl_verifyhost when its call to Curl_parseX509 fails so the change makes error handling more consistent.

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.

2016-10-31strcasecompare: is the new name for strequal()Daniel Stenberg
... to make it less likely that we forget that the function actually does case insentive compares. Also replaced several invokes of the function with a plain strcmp when case sensitivity is not an issue (like comparing with "-").

Closes #822
2016-04-29lib: include curl_printf.h as one of the last headersDaniel Stenberg
curl_printf.h defines printf to curl_mprintf, etc. This can cause problems with external headers which may use __attribute__((format(printf, ...))) markers etc. To avoid that they cause problems with system includes, we include curl_printf.h after any system headers. That makes the three last headers to always be, and we keep them in this order: curl_printf.h curl_memory.h memdebug.h None of them include system headers, they all do funny #defines.

2015-12-15x509asn1: Fix host altname verificationJay Satiro
- In Curl_verifyhost check all altnames in the certificate. Prior to this change only the first altname was checked. Only the GSKit SSL backend was affected by this bug. Bug: http://curl.haxx.se/mail/lib-2015-12/0062.html Reported-by: John Kohl
2015-11-24Revert "cleanup: general removal of TODO (and similar) comments"Daniel Stenberg
This reverts commit 64e959ffe37c436503f9fed1ce2d6ee6ae50bd9a. Feedback-by: Dan Fandrich URL: http://curl.haxx.se/mail/lib-2015-11/0062.html
2015-11-13cleanup: general removal of TODO (and similar) commentsDaniel Stenberg
They tend to never get updated anyway so they're frequently inaccurate and we never go back to revisit them anyway. We document issues to work on properly in KNOWN_BUGS and TODO instead.
2015-04-22cyassl: Implement public key pinningJay Satiro
Also add public key extraction example to CURLOPT_PINNEDPUBLICKEY doc.
2015-04-06x509asn1: Silence x64 loss-of-data warning on RSA key length assignmentJay Satiro
The key length in bits will always fit in an unsigned long so the loss-of-data warning assigning the result of x64 pointer arithmetic to an unsigned long is unnecessary.

2015-03-21x509asn1: minor edit to unconfuse CoverityDaniel Stenberg
CID 1202732 warns on the previous use, although I cannot fine any problems with it. I'm doing this change only to make the code use a more familiar approach to accomplish the same thing.

2015-03-16Bug #149: Deletion of unnecessary checks before calls of the function "free"Markus Elfring
The function "free" is documented in the way that no action shall occur for a passed null pointer. It is therefore not needed that a function caller repeats a corresponding check. http://stackoverflow.com/questions/18775608/free-a-null-pointer-anyway-or-check-first This issue was fixed by using the software Coccinelle 1.0.0-rc24.

2015-03-03mprintf.h: remove #ifdef CURLDEBUGDaniel Stenberg
... and as a consequence, introduce curl_printf.h with that re-define magic instead and make all libcurl code use that instead.
2014-10-24code cleanup: we prefer 'CURLcode result'Daniel Stenberg
... for the local variable name in functions holding the return code. Using the same name universally makes code easier to read and follow. Also, unify code for checking for CURLcode errors with: if(result) or if(!result) instead of if(result == CURLE_OK), if(CURLE_OK == result) or if(result != CURLE_OK)
