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.

5 * This file implements PKCS 11 on top of our existing security modules
6 *
7 * For more information about PKCS 11 See PKCS 11 Token Inteface Standard.
8 * This implementation has two slots:
9 * slot 1 is our generic crypto support. It does not require login
10 * (unless you've enabled FIPS). It supports Public Key ops, and all they
11 * bulk ciphers and hashes. It can also support Private Key ops for imported
12 * Private keys. It does not have any token storage.
13 * slot 2 is our private key support. It requires a login before use. It
14 * can store Private Keys and Certs as token objects. Currently only private
15 * keys and their associated Certificates are saved on the token.
16 *
17 * In this implementation, session objects are only visible to the session
18 * that created or generated them.
