How to fix a cURL error 60: SSL certificate problem using a PutObject in AWS

cURL is looking for an ssl certificate in your local installation. There are two ways to solve the issue. It depends on the one you prefer.

Option 1

If you are using Laravel, tell your software not to use https when uploading to AWS s3 disk. To do this, head over to config/filesystems.php and add 'scheme' => 'http', in 's3' array. Assuming you have a fresh laravel installation, your new s3 array will now look like below:

    's3' => [
        'driver' => 's3',
        'key' => env('AWS_ACCESS_KEY_ID'),
        'secret' => env('AWS_SECRET_ACCESS_KEY'),
        'region' => env('AWS_DEFAULT_REGION'),
        'bucket' => env('AWS_BUCKET'),
        'url' => env('AWS_URL'),
        'endpoint' => env('AWS_ENDPOINT'),
        'scheme'  => 'http',
    ],

That is all you need to do. Go ahead and upload your file.

Option 2

Download cacert.pem and update your php.ini.

To do this, head over to https://curl.haxx.se/ca/cacert.pem and download the cacert.pem file. Copy the file to your php version folder (on Windows, this might look like C:\wamp64\bin\php\php8.3.0 or wherever you installed your WAMP or Xampp). After that, note the location of the file.

Go to your your php.ini file and search for the line containing curl.cainfo.

Update that line to curl.cainfo = "C:\wamp\bin\php\php7.2.3\cacert.pem".

Go ahead and upload your files.

Note:

The above two methods are just for development purposes only. Option 1 actually disables the need for ssl in your requests to AWS while option 2 does not replace the need for an actual SSL Certificate. While going to production, remember to disable option 1 and get your website secured with an SSL certificate.
