警告：openssl_pkcs7_sign（）[function.openssl-pkcs7-sign]：在第8366行的C：\ xampp \ htdocs \ this \ tcpdf \ tcpdf.php中获取私钥时出错

Question

I am using TCPDF to sign PDF, but when running the example 52 I got this error:

Warning: openssl_pkcs7_sign() [function.openssl-pkcs7-sign]: error getting 
private key in C:\xampp\htdocs\this\tcpdf\tcpdf.php on line 8366

Could you please tell me or guide me where is the problem. I am just running the example without changing anything. I am using xampp.

Answer 1

The problem is with the location from where it tries to access the private key. Instead of '' like in their example use 'file://'.( dirname(FILE)).'./path/to/file'. This worked for me.
