1.0.3 - SSLv3 Support and Enhancements

Release 8.17.0 Library and Headers

This release includes cURL, OpenSSL and Nghttp2 libraries and header files for MacOS, Mac Catalyst, iOS and tvOS projects.

• Added SSLv3 support for security testing with -3 flag. This allows verification that servers properly reject SSLv3 connections. Includes compatibility updates for OpenSSL 3.x which removed the SSLv3_client_method() function.
• Enhanced SSLv3 patch (sslv3.patch) to work with OpenSSL 3.x using SSL_CTX_set_min_proto_version() and SSL_CTX_set_max_proto_version() APIs.
• Added automatic SSLv3 support verification in build script when -3 flag is used.
• Updated iCurlHTTP.sh script to copy all .xcframework folders from archive/latest/xcframework to support modern Xcode projects.
• Fixed libcurl-build.sh SSLv3 patching for curl 8.17.0+ to properly handle the new command-line argument processing in tool_getparam.c.
• Improved documentation with detailed patch file comments.

Usage

1. Copy headers to your project.
2. Import XCFrameworks: Import appropriate xcframework folders into your project in Xcode.
   Alternative: Import appropriate libraries: "libssl.a", "libcrypto.a", "libcurl.a", "libnghttp2.a"
3. Reference Headers.
4. If required, specify the flag "-lz" in "Other Linker Flags" (OTHER_LDFLAGS) setting in the "Linking" section in the Build settings of the target.
5. Initialize curl in your code:

        #include <curl/curl.h>

        (void)foo {    
            CURL* cURL = curl_easy_init();  
            // ...  
        }
