    <p>I'm almost losing hope on this one. I'm trying to access the Firefox trust store from Java 7 using the NSS libraries that come with the Firefox installation, via PKCS#11.</p> <p>Here is the code:</p> <pre><code>import java.security.KeyStore; import java.security.Security; import java.util.Enumeration; import sun.security.pkcs11.SunPKCS11; public class Test { public static void main(String[] args) throws Exception { String configName = "pkcs11.cfg"; SunPKCS11 p = new SunPKCS11(configName); Security.addProvider(p); KeyStore ks = KeyStore.getInstance("PKCS11", p); ks.load(null, "apassword".toCharArray()); System.out.println("Size: " + ks.size()); Enumeration&lt;String&gt; aliases = ks.aliases(); while (aliases.hasMoreElements()) { System.out.println(aliases.nextElement()); } } } </code></pre> <p>Here are the contents for the PKCS#11 config:</p> <pre><code>name = NSS nssLibraryDirectory = /usr/lib/firefox/ nssSecmodDirectory = "/home/bogdan/.mozilla/firefox/x5d8wol9.default/" nssModule =trustanchors showInfo = true </code></pre> <p>When I run the application I also set the property <code>-Djava.library.path=/usr/lib/firefox/</code></p> <p>When I run the application I get the following:</p> <pre><code>NSS modules: [NSS Internal PKCS #11 Module (CRYPTO, /usr/lib/firefox/libsoftokn3.so, slot 0), NSS Internal PKCS #11 Module (KEYSTORE, /usr/lib/firefox/libsoftokn3.so, slot 1)] Exception in thread "main" java.security.ProviderException: NSS module not available: trustanchors at sun.security.pkcs11.SunPKCS11.&lt;init&gt;(SunPKCS11.java:271) at sun.security.pkcs11.SunPKCS11.&lt;init&gt;(SunPKCS11.java:103) at Test.main(Test.java:11) </code></pre> <p>You can actually see that the "trustanchors" module is not loaded at the initialisation step, but I have no idea why. The documentation here: <a href="http://docs.oracle.com/javase/6/docs/technotes/guides/security/p11guide.html#NSS" rel="nofollow">http://docs.oracle.com/javase/6/docs/technotes/guides/security/p11guide.html#NSS</a> says that </p> <blockquote> <p>The trustanchors module enables access to NSS trust anchor certificates via the PKCS11 KeyStore, if secmod.db has been configured to include the trust anchor library.</p> </blockquote> <p>but I have no idea what that means. It's worth noting that I get the same behaviour with both Windows XP 32 bit and Ubuntu 11.10 64-bit. It seems that the pkcs11.cfg is correct as if I change any of the paths the application will fail with other errors.</p> <p>Any bright ideas?</p>

    2. COThe Root certificate module does appear if I list it with `modutil -list -dbdir /home/bogdan/.mozilla/firefox/x5d8wol9.default/`

    3. COI think the problem is related to the fact that it thinks that this module uses the library "/home/bogdan/.mozilla/firefox/x5d8wol9.default/libnssckbi.so", but this file doesn't exist. I tried to copy it there and now I get this failure: `Exception in thread "main" java.security.ProviderException: Library /usr/lib/firefox/home/bogdan/.mozilla/firefox/x5d8wol9.default/libnssckbi.so does not exist` (notice the weird path which is a concatenation with LD_LIBRARY_PATH)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
