我研究过如何使用Sun PKCS#11 api访问DoD CAC,并可能使用CAC访问(只读)Active Directory。我的问题是,我在大多数情况下发现的将引用一些代码,但从不显示引用的代码。我找到了以下代码,但是给出了错误。有没有人知道任何代码示例或使用PKCS11进行CAC的明确文档?或者可能有效的API解决方案?
import java.io.*;
import java.util.*;
import java.security.cert.CertificateException;
import java.security.KeyStoreException;
import java.security.cert.X509Certificate;
import java.security.KeyStore;
import java.security.Provider;
import java.security.Security;
public class SmartCard {
public static void main(String[] args) throws Exception {
try {
String configName = "pkcs11.properties";
Provider p = new sun.security.pkcs11.SunPKCS11(configName);
Security.addProvider(p);
Console c = System.console();
char[] pin = c.readPassword("Enter your PIN: ");
KeyStore cac = null;
cac = KeyStore.getInstance("PKCS11");
cac.load(null, pin);
showInfoAboutCAC(cac);
}
catch(Exception ex) {
ex.printStackTrace();
System.exit(0);
}
}
public static void showInfoAboutCAC(KeyStore ks) throws KeyStoreException, CertificateException {
Enumeration<String> aliases = ks.aliases();
while(aliases.hasMoreElements()) {
String alias = aliases.nextElement();
X509Certificate[] cchain = (X509Certificate[]) ks.getCertificateChain(alias);
System.out.println("Certificate Chain for " + alias);
for(int i = 0; i < cchain.length; i++) {
System.out.println(" -SubjectDN: " + cchain[i].getSubjectDN());
System.out.println(" -IssuerDN: " + cchain[i].getIssuerDN());
}
}
}
}

在以下代码中,configName
应该是某个配置文件的文件路径。它不存在,或者java无法读取它,因此抛出IOException
。弄清楚该文件应该是什么并创建它,或者确保java有权访问该文件,并且代码将会运行。
String configName = "pkcs11.properties";
Provider p = new sun.security.pkcs11.SunPKCS11(configName);
阅读手册可能会有所帮助: http://docs.oracle.com/javase/8/docs/technotes/guides/security/p11guide.html#Config

属性文件确实存在,并且与应用程序位于同一目录中。据我所知,Java可以访问该文件。
如果有帮助,这是文件的内容:
name=SmartCard
library=C:/Program Files/Java/jre7/bin/j2pkcs11.dll
