this is slightly off-topic for this mailinglist, but I'd try using 
p11-kit to access the NSS device; the problem with the softokn3 
pseudo-pkcs11 device is/was that it did not follow the PKCS11 standard 
completely - this made the softokn3 device unusable for tools like 
libp11 and opensc ; however, there are links on the web stating that 
p11-kit does not how to read a nssdb file, e.g.
https://wiki.gnome.org/Projects/CryptoGlue/Integration#NSS_libsoftokn3

and p11-kit has been ported to both mingw and cygwin.
