Create a Dynamic Web Project in Eclipse. Let's say the name of the project is SSL.
In the left panel of Eclipse, at the name of your project (SSL in this example) > Java Resources > src, create a new package. For the sake of this tutorial, let's name the package com.ssl.demo.
In the package, create a class called SSL.java. In SSL.java, add the following markup
package com.ssl.demo;
import java.io.FileInputStream;
import java.security.KeyStore;
import java.security.PrivateKey;
import java.security.KeyStore.*;
public class SSL {
public PrivateKey getPrivateKey() throws Exception {
String alias = "foo-certificate";
char[] password = "itsasecret".toCharArray();
KeyStore keystore = KeyStore.getInstance("PKCS12");
keystore.load(new FileInputStream("C:\\Users\\john.doe\\eclipse-workspace\\keystore.p12"), pwdArray);
PrivateKeyEntry entry = (PrivateKeyEntry)keystore.getEntry(alias, new PasswordProtection(password.toCharArray()));
System.out.println("entry.getPrivateKey = " + entry.getPrivateKey());
return entry.getPrivateKey();
}
}
In the left panel of Eclipse, right click on the name of your project (demo in this example) and select New > JSP File. Select the WebContent folder, give the file a name such as index.jsp, and select Finish.
Add the following to line 1 of the JSP file. This is the combination of the package (com.ssl.demo) and the class (SSL.java).
<%@page import="com.ssl.demo.SSL"%>
Add the following inside the <body> tags.
- In this example, "SSL" must be used because the name of the class in SSL.java is SSL.
- In this example, "getPrivateKey" must be cause because the name of the method in SSL.java is getPrivateKey.
<body>
<%
SSL foo = new SSL();
out.println(foo.getPrivateKey());
%>
</body>
Select the green play button in Eclipse, and hopefully something like this is returned.
