Digital Certificate

[kill-9]

Hi,

   I was trying to use minisip in my work, using encrypt features. I have digital certificate, in my smartcard, and I try to use it, but the minisip only accept digital certificate in a file. My certificate is in a smartcard. An example, the firefox works asking for a driver, and when I give it to him, he ask me for my pin and the ssl connect works with certificate. Can I use this certificate with minisip?

Thanks.
