 ## Bugs
-- **Memory Leak**: The `buffer` variable is dynamically allocated memory in both `http_post` and `http_get` but is never freed.
-- **Use of Deprecated Function**: `EVP_cleanup()` is deprecated in OpenSSL 1.1.0 and should not be used.
-- **Potential Security Risk**: `gethostbyname()` is obsolete and may be unsafe; consider using `getaddrinfo()` instead.
-- **Error Handling**: Error messages from `SSL_read()` and `SSL_write()` are not fully managed; they should handle all negative return values properly, not just zero.
+- `create_context` and `create_context2` functions are redundant; however, only `create_context2` performs error checking, which is crucial.
+- Use of `gethostbyname` is deprecated; it should be replaced with more modern alternatives like `getaddrinfo`.
+- `api_key` is used within `http_post` and `http_get` functions without being defined in the code.
+- Risk of memory leak when reallocating the buffer if `realloc` fails, the original buffer is not freed, and the system would have reduced memory.
+- `close(sock)` does not check for errors.
 
 ## Optimizations
-- Reuse the SSL context and socket code by creating utility functions to avoid redundancy between `http_post` and `http_get`.
-- Error message functions and SSL context setup can be extracted into separate utility functions to reduce code duplication.
-- The buffer resizing logic can be optimized to avoid frequent reallocations by increasing the buffer size exponentially instead of linearly when limits are approached.
+- Consolidate `create_context` and `create_context2` into a single function to avoid redundancy and potential maintenance issues.
+- Use `getaddrinfo` instead of `gethostbyname` for better compatibility and thread safety.
+- Include proper error handling if `realloc` fails to make efficient memory management.
+- Specify size when using `malloc` or `realloc` for buffer to enhance readability and maintenance.
+- Use `snprintf` instead of `sprintf` to avoid buffer overflow vulnerabilities.
 
 ## Good points
-- Uses `json-c` library which simplifies JSON data manipulation.
-- Appropriate use of OpenSSL for secure communication.
-- Includes comprehensive basic includes for socket and SSL handling.
-- The code structure is organized into functions for clarity.
+- Proper initialization and cleanup of OpenSSL.
+- Effective use of OpenSSL APIs to set up TLS/SSL connections.
+- Clear function separation for handling different tasks like initializing SSL, creating sockets, and managing HTTP requests.
+- Usage of dynamic memory management for buffer handling shows good understanding.
 
 ## Summary
-The code provides HTTP communication functions over SSL/TLS. It features both POST and GET requests and includes basics such as initialization and cleanup of OpenSSL. However, there are issues related to deprecated functions, inefficient error handling, memory management, and certain parts of the code are repeated unnecessarily. Addressing these concerns will improve efficiency and security, and make the code cleaner and more maintainable.
+The code demonstrates an understanding of OpenSSL API for creating secure HTTP connections over SSL/TLS, and effectively segregates the key functionalities. However, there are a few significant issues that need addressing, including handling deprecated functions, managing possible memory leaks, and ensuring error checking across all parts of the code. The use of global `api_key` is problematic since its source isn't evident within the code snippet. Memory handling and duplication of functions are areas where optimizations could significantly enhance the robustness and efficiency of the code.
 
 ## Open source alternatives
-- **cURL**: A robust tool for sending and receiving data with URL syntax; provides extensive features for HTTP requests.
-- **libcurl**: The library version of cURL, which can be used within applications to leverage cURL's capabilities.
-- **neon**: An HTTP and WebDAV client library with a high-level interface wrapped around the lower-level Libxml and OpenSSL.
+- **Libcurl**: A widely used library that offers a simple and consistent API for making HTTP requests, supporting a variety of protocols and features including SSL/TLS.
+- **Boost.Beast**: This C++ library is part of the Boost collection, providing an HTTP and WebSocket client and server built on top of Boost.Asio. It offers SSL/TLS support via OpenSSL.
+- **HttpClient in Poco**: The POCO C++ Libraries offer components that simplify HTTP/S communications, including robust support for SSL/TLS.
