For RSA and DSA keys return an appropriate RecipientInfo type. By setting CMS_RECIPINFO_NONE for DSA keys an appropriate error is returned if an attempt is made to use DSA with enveloped data.
The stuff in here is based on patches supplied to me by Steven Schoch <schoch@sheba.arc.nasa.gov> to do DSS. I have since modified a them a little but a debt of gratitude is due for doing the initial work.
