Here you can find the direct download link for Curl.exe. I was looking for the download process of Curl and every where they said copy curl.exe file in System32 but they haven't provided the direct link but after digging little more I Got it. So here it is enjoy, find curl.exe easily in bin folder just. Unzip it and then go to bin folder there you get exe file. I'm using Terminal on Mac OS X 10.11.2 and I can't process any https requests. I always get this error: curl: (1) Protocol 'https' not supported or disabled in libcurl I tried this but I get a 'w. CURL is a command line tool for transferring files with URL syntax, supporting FTP, FTPS, TFTP, HTTP, HTTPS, TELNET, DICT, FILE and LDAP. Curl supports SSL.

Curl command file utility supports for downloading and uploading files. Curl is useful for many works with system administration, web development for calling web services, etc. In this tutorial we are providing 5 curl frequently used commands to download files from remote servers.
1. cURL Command to Download and Save File
To simply download a file using curl use following syntax. -O is used for saving file on the local system with the same name on the remote system.
2. cURL Download and Save with Other Name
If you want to save file with different name on local system, Use -o with new file name.
3. cURL to Download Multiple Files
Curl also provides an option to download multiple files simultaneously. To download multiple file use following syntax. All files will be saves with original file names.
4. Passing Login Credential with cURL Download![]()
In case files are behind authenticated http or ftp server. You can pass login credentials using -u command line parameter like below examples.
5. cURL Download File via Proxy Server
If server file is only available through a proxy server, or you want to use a proxy for downloading files, Use -x followed by proxy address and port to download the file via a proxy server.

CA extract SSL is TLS
SSL is the old name. It is called TLS these days.
Native SSL
If libcurl was built with Schannel or Secure Transport support (the native SSLlibraries included in Windows and Mac OS X), then this does not apply toyou. Scroll down for details on how the OS-native engines handle SSLcertificates. If you're not sure, then run 'curl -V' and read the results. Ifthe version string says
Schannel Make a webcam an ip cam download mac. in it, then it was built with Schannelsupport.
It is about trust
This system is about trust. In your local CA certificate store you have certsfrom trusted Certificate Authorities that you then can use to verify that theserver certificates you see are valid. Download full version of zoo tycoon 2 mac. Mac Miller - Dang! (feat. Anderson .Paak) by Mac Miller .... They're signed by one of the CAs youtrust.
Which CAs do you trust? You can decide to trust the same set of companies youroperating system trusts, or the set one of the known browsers trust. That'sbasically trust via someone else you trust. You should just be aware thatmodern operating systems and browsers are setup to trust hundreds ofcompanies and recent years several such CAs have been found untrustworthy.
Certificate Verification
libcurl performs peer SSL certificate verification by default. This is doneby using a CA certificate store that the SSL library can use to make sure thepeer's server certificate is valid.
If you communicate with HTTPS, FTPS or other TLS-using servers usingcertificates that are signed by CAs present in the store, you can be surethat the remote server really is the one it claims to be.
If the remote server uses a self-signed certificate, if you don't install a CAcert store, if the server uses a certificate signed by a CA that isn'tincluded in the store you use or if the remote host is an impostorimpersonating your favorite site, and you want to transfer files from thisserver, do one of the following:
Neglecting to use one of the above methods when dealing with a server using acertificate that isn't signed by one of the certificates in the installed CAcertificate store, will cause SSL to report an error ('certificate verifyfailed') during the handshake and SSL will then refuse further communicationwith that server.
Certificate Verification with NSS
If libcurl was built with NSS support, then depending on the OS distribution,it is probably required to take some additional steps to use the system-wideCA cert db. RedHat ships with an additional module, libnsspem.so, whichenables NSS to read the OpenSSL PEM CA bundle. On openSUSE you can installp11-kit-nss-trust which makes NSS use the system wide CA certificate store. NSSalso has a new database format.
Starting with version 7.19.7, libcurl automatically adds the 'sql:' prefix tothe certdb directory (either the hardcoded default /etc/pki/nssdb or thedirectory configured with SSL_DIR environment variable). To check which certdbformat your distribution provides, examine the default certdb location:/etc/pki/nssdb; the new certdb format can be identified by the filenamescert9.db, key4.db, pkcs11.txt; filenames of older versions are cert8.db,key3.db, secmod.db.

Certificate Verification with Schannel and Secure Transport
If libcurl was built with Schannel (Microsoft's native TLS engine) or SecureTransport (Apple's native TLS engine) support, then libcurl will still performpeer certificate verification, but instead of using a CA cert bundle, it willuse the certificates that are built into the OS. These are the samecertificates that appear in the Internet Options control panel (under Windows)or Keychain Access application (under OS X). Any custom security rules forcertificates will be honored.
Schannel will run CRL checks on certificates unless peer verification isdisabled. Secure Transport on iOS will run OCSP checks on certificates unlesspeer verification is disabled. Secure Transport on OS X will run either OCSPor CRL checks on certificates if those features are enabled, and this behaviorcan be adjusted in the preferences of Keychain Access.

Since version 7.52.0, curl can do HTTPS to the proxy separately from theconnection to the server. This TLS connection is handled separately from theserver connection so instead of
--insecure and --cacert to control thecertificate verification, you use --proxy-insecure and --proxy-cacert .With these options, you make sure that the TLS connection and the trust of theproxy can be kept totally separate from the TLS connection to the server.
