Call to undefined function openssl_pkcs7_sign()

Question

I'm using TCPDF to sign son PFD documents. I was testing the examples via web: http://www.tcpdf.org/examples.php, and they worked fine, but when I downloaded the lib and tested it @ localhost I got this error in "example 52":

Fatal error: Call to undefined function openssl_pkcs7_sign() in C:\xampp\htdocs\pruebas\pdf_firma\tcpdf\tcpdf.php on line 9043

My PHP is Version 5.3.8.

Any has any idea how to fix it?
