This is NSS with a Cmake Buildsyste To compile a static NSS library for Windows we've used the Chromium-NSS fork and added a Cmake buildsystem to compile it statically for Windows. See README.chromium for chromium changes and README.trustbridge for our modifications.

20 /* Non-opaque objects. NOTE, though: I want them to be treated as
21 * opaque as much as possible. If I could hide them completely,
22 * I would. (I tried, but ran into trouble that was taking me too
23 * much time to get out of.) I still intend to try to do so.

27 /* rjr: PKCS #11 cert handling (pk11cert.c) does use NSSCMSRecipientInfo's.
28 * This is because when we search the recipient list for the cert and key we
29 * want, we need to invert the order of the loops we used to have. The old
30 * loops were:
31 *
32 * For each recipient {
33 * find_cert = PK11_Find_AllCert(recipient->issuerSN);
34 * [which unrolls to... ]
35 * For each slot {
36 * Log into slot;
37 * search slot for cert;
38 * }
39 * }
40 *
41 * the new loop searchs all the recipients at once on a slot. this allows
42 * PKCS #11 to order slots in such a way that logout slots don't get checked
43 * if we can find the cert on a logged in slot. This eliminates lots of
44 * spurious password prompts when smart cards are installed... so why this
45 * comment? If you make NSSCMSRecipientInfo completely opaque, you need
46 * to provide a non-opaque list of issuerSN's (the only field PKCS#11 needs
47 * and fix up pk11cert.c first. NOTE: Only S/MIME calls this special PKCS #11
48 * function.
