TCPDF: getimagesize(): SSL operation failed with code 1 error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed

Question

I've been using TCPDF. In my local machine, TCPDF works fine, but it throws an error in the actual server. The error message is as follows.

Message: getimagesize(): SSL operation failed with code 1. OpenSSL Error messages: error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed

Message: getimagesize(): Failed to enable crypto

getimagesize(http:/test.com/images/sample.jpg): failed to open stream: operation failed

If I understand them right, this application couldn't verify the SSL certificate of the server.

So, following this example , I put get the signature in the following way.

$pdf  = new TCPDF();
$certificate = '/blahblah/certs/certificate.crt';
$pdf->setSignature($certificate, $certificate, 'pdfgen', '', 2, []);

Still, I'm seeing the same error.

When TCPDF throws this "SSL operation failed with code 1" error, what does it mean?

Any help will be appreciated.

Answer 1

I had the same problem using the library html2pdf that needs to get the image size through the PHP function getsizeimage() and my image URL was with https so I solved by specifying in my php.ini file the SSL certificate.

[openssl]
openssl.cafile="/etc/nginx/tls/yourCert.crt"

或者您可能在本地尝试 HTTP，然后在实时服务器上更改为 HTTPS

This Problem take me hours! I have a ngnix Server. The only thing I had to do is to paste the content of "mykey.ca" file at the end of the "mykey.crt" file, save it as new file "newBothKey.crt" and set this file in "/etc/nginx/sites-available"

listen 443 ssl;
ssl on;
ssl_certificate /etc/nginx/.ssl/sitename/newBothKey.crt;
ssl_certificate_key /etc/nginx/.ssl/sitename/mykey.key;
ssl_protocols TLSv1.2;

Don't forget to restart nginx:

sudo systmctl restart nginix
