    Hi. I've developed a custom CSP and Certificate Store Provider. I was
    testing CAPICOM and trying to sign a document with my csp. I always get an
    error in the signing process.

    I've been watching the logs of my CSP and the Crypto SPI functions called
    are (in this order):


    CPExportKey returns a NTE_BAD_KEY_STATE error because my keys are stored
    as non-exportable. If i store them as exportable CAPICOM returns no error
    and the signature is correctly verified.

    Any idea of what can i'm doing wrong? I don't know why CAPICOM is trying
    to export a key that is not exportable and don't need to be exportable...

    Thanks in advance.
