When I sign a pdf file the System ask me to put a PIN code, after this it Signs it. This for every document.

Is there a way to input the PIN code only one time and to Sign all pdf files present into a folder?

The general idea is to use the same certificate object throughout the process. Please load the certificate just once from Win32 or PKCS#11 system store and keep the storage object opened while the signing is being carried out. In most of the cases it will eliminate the issue for you. If it won't, the problem is in the underlying HSM driver, and this is not fixable technically on our side.

I assume you're working with CryptoAPI certificates, if you're working with software certificates, set their security level to middle, if you're working with hardware certificates (smartcard, tokens) depends on the security the smartcard developers have implemented on their CSP (the cryptoprovider they put for Windows to see your certificate). I've found in my life with some paranoic CSP's :).

The solution with paranoic hardware tokens for me at least was to use them through PKCS#11 instead of CryptoAPI, so the user just has to enter the PIN the first login time. Note that some CSP's also ask for confirmation of each signature in PKCS#11 :(, you've got to try and test

Hope it helps
