/* rjr: PKCS #11 cert handling (pk11cert.c) does use SEC_PKCS7RecipientInfo's.
* This is because when we search the recipient list for the cert and key we
* want, we need to invert the order of the loops we used to have. The old
* loops were:
*
* For each recipient {
* find_cert = PK11_Find_AllCert(recipient->issuerSN);
* [which unrolls to... ]
* For each slot {
* Log into slot;
* search slot for cert;
* }
* }
*
* the new loop searchs all the recipients at once on a slot. this allows
* PKCS #11 to order slots in such a way that logout slots don't get checked
* if we can find the cert on a logged in slot. This eliminates lots of
* spurious password prompts when smart cards are installed... so why this
* comment? If you make SEC_PKCS7RecipientInfo completely opaque, you need
* to provide a non-opaque list of issuerSN's (the only field PKCS#11 needs
* and fix up pk11cert.c first. NOTE: Only S/MIME calls this special PKCS #11
* function.
