Hi there,
how can i access the Mozilla NSS (shared) Database (cert8 or
cert9d.db) / PKCS#11-Modules via OpenSSL?
I need read & write access to the NSS User Cert Database (softokn3)
and to the Built-In Cert Database (nssckbi) under Windows.
I tried it with Libp11 this way:
int rc = 0;
PKCS11_CTX *pkcs11_ctx;
pkcs11_ctx = PKCS11_CTX_new();
PKCS11_CTX_init_args(pkcs11_ctx,
"configdir=''C:/Users/Username/AppData/Roaming/Mozilla/Firefox/Profiles/5wzkdcjx.default'
certPrefix='' keyPrefix='' secmod='secmod.db'");
rc = PKCS11_CTX_load(pkcs11_ctx, " C:/Program Files
(x86)/Mozilla/Firefox/softokn3.dll ");
printf("Desc: %s\n", pkcs11_ctx->description);
if (rc)
printf("Error loading Module");
But it return every time “-1” which tells me that the loading fails.
So is this the right way? Or should I use another library? Or is my
code not right?
And can I edit the Trust Settings with that or another library like
with NSS directly? Because I can’t delete the built-in certs of
nssckbi because this is read-only I can edit the Trust-Settings for
that certificate. Can I do that with OpenSSL in combination with a
library, too? Or should I better use NSS instead of OpenSSL?
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.
