    <p>I am building a cryptographic web application, which allows user to sign and encrypt on client side within browser. The application has to be compatible with IE and Firefox. It works perfectly fine in Firefox in IE I am facing one issue.</p> <p>Recently, Government of India started issuing two digital certificates to individuals one for signing data and one for encryption. These certificates have same CN. I am using following code to loop through certificates.</p> <pre><code>public static Certificate selectedCert = null; KeyStore keystore1 ; keystore1 = KeyStore.getInstance("Windows-MY"); keystore1.load(null, null); if (keystore1 != null) { enumeration = keystore1.aliases(); while (enumeration.hasMoreElements()) { alias = enumeration.nextElement(); selectedCert = keystore1.getCertificate(alias)); System.out.println(selectedCert.getPublicKey()); } } </code></pre> <p>While reading certificate from firefox keystore the alias names are generated by firefox which are unique but in case of IE, it takes certificates from IE it takes Common Name (CN) as alias. That way it gets two such entries with same alias. Now whenever I want to get the whole certificate object I have to pass alias, so whenever I pass alias it will always give me first certificate and I am unable to access the second certificate with same alias name.</p> <p>To clarify more, if I have two certificates in the name of "Kuntal Shah" and one in name of "Abhishek Desai". Then the aliases enumeration will have "Kuntal Shah" "Kuntal Shah" "Abhishek Desai" when I do </p> <pre><code>selectedCert = keystore1.getCertificate(alias)); </code></pre> <p>It always returns me the first one and I am never able to get the second one.</p> <p>I tried some code in C#, there I have a simpler solution</p> <pre><code>X509Store storeMy = new X509Store(StoreName.My,StoreLocation.CurrentUser); storeMy.Open(OpenFlags.ReadOnly); Console.WriteLine("Found certs with the following subject " +"names in the {0} store:", storeMy.Name); foreach (X509Certificate2 cert in storeMy.Certificates) { Console.WriteLine("\t{0}", cert.SubjectName.Name); } </code></pre> <p>But this does not work with firefox and it will not work on Linux.</p> <p>Can any one tell me how do I access the second certificate? or is there any other different way all together?</p>

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.
