I’m on Windows with XAMPP and Composer refuses to install or update because of the classic “OpenSSL certificate verify failed” message. The installer points to C:\xampp\apache\bin\curl-ca-bundle.crt and my CLI is using C:\xampp\php\php.ini. Internet connection is stable, so the block is clearly the SSL handshake. I need clear, step-by-step help to: • Replace or correctly register the CA bundle used by curl/OpenSSL. • Adjust any php.ini or environment path settings so Composer can reach https://getcomposer.org/versions without errors. • Verify the fix by running composer self-update successfully. A quick remote session or a concise set of commands with explanations is perfect—I just want Composer up and running again today.
