sun.security.pkcs11.wrapper.PKCS11Exception: CKR_ATTRIBUTE_TYPE_INVALID

Question

我是SmartCard新手，需要一些帮助。我尝试运行一个测试程序(见下文)，但是一直得到这个异常，sun.security.pkcs11.wrapper.PKCS11Exception: CKR_ATTRIBUTE_TYPE_INVALID。

我的系统是Windows 7 64-bit，java版本是1.8.0_31。

提前感谢您的帮助！

public static void main(String[] args) throws Exception { 
    final StringBuilder buff = new StringBuilder(); 
    buff.append("name=").append("SmartCard").append("\n"); 
    buff.append("library=").append("C:\\Progra~1\\ActivIdentity\\ActivClient\\acpkcs211.dll").append("\n");
    buff.append("showInfo=true").append("\n"); 
    buff.append("slotListIndex=0").append("\n"); 

    final SunPKCS11 provider = new sun.security.pkcs11.SunPKCS11(new ByteArrayInputStream(buff.toString().getBytes())); 
    Security.addProvider(provider);  

    KeyStore.ProtectionParameter pp = new KeyStore.PasswordProtection("######".toCharArray());  
    KeyStore.Builder builder = KeyStore.Builder.newInstance("PKCS11", provider, pp);
    KeyStore ks = builder.getKeyStore(); 
    ks.load(null, null); 
} 

输出：

Answer 1

我认为CKR_ATTRIBUTE_TYPE_INVALID错误表明传递的某个属性(可能是showInfo或slotListINdex)无效。尝试逐个删除它们，看看它是否修复了错误。
