Troubleshooting "A Problem Occurred Somewhere in the SSL/TLS Handshake" Error in cURL

When attempting to establish HTTPS connections with cURL, developers may encounter the following error:

A problem occurred somewhere in the SSL/TLS handshake.

This issue arises due to cURL not having built-in root certificates like modern browsers. To resolve it, follow these steps:

Solution:

1. Download the cacert.pem certificate file from http://curl.haxx.se/docs/caextract.html.
2. Configure cURL to point to this file using the CURLOPT_CAINFO option:

<code class="php">curl_setopt($ch, CURLOPT_CAINFO, '/path/to/cert/file/cacert.pem');</code>

This specifies the location of the trusted root certificates that cURL should use to verify SSL certificates sent back by servers.

Additional Tips:

• Ensure that OpenSSL is installed and enabled on your system.
• Set CURLOPT_SSL_VERIFYPEER to true to enable certificate verification.
• Try different combinations of CURLOPT_SSL_VERIFYHOST (1 or 2) and CURLOPT_SSL_VERIFYPEER (true or false) to troubleshoot further.
