put x509 certificate inside a file
 

Hello, i'm a new user from italy.

I've a big problem:
I really need to use a beta application that works only with certified (or signed) files. How can i sign my files (they are about 50mb each one)
If i try to open the working example given with the SW i obtain this output from line 23
