Hi there, I'm new to all this digital certificates and signing pdf, so
I'm trying to make a program to sign PDF files with a Digital
Certificate in a Smart Card.
I'm able to do it with a development certificate generated by me, but
when I try to sign with my Digital Certificate generated by the CA of
my country, can't do it. When I try to export the Private Key it does
not find it, actually it's is not in Pkcs12Store.
If I check the certificate in my machine it has a Private Key, but
when I try to export the certificate It contains a restriction to
export the private key.
There is any difference when I work with this certificates?
Of course there is!
Your smart card would be very insecure if you were able to export the
private key. Isn't this obvious?
It should also be obvious that you shouldn't use PKCS#12 when you're
supposed to use PKCS#11.
There is EXCELLENT documentation available here:
