PKCS#11生成AES密钥

Question

嘿,问题不是关于Ncryptoki,但我不知道其他地方要问..所以如果有人可以帮助请帮助我.我试着生成AES密钥,然后是我现在拥有的代码:

CK_MECHANISM keyGenMech = new CK_MECHANISM(CKM.AES_KEY_GEN);

CK_ATTRIBUTE[] template =
{
    new CK_ATTRIBUTE(CKA.CLASS, CKO.SECRET_KEY),
    new CK_ATTRIBUTE(CKA.TOKEN, CK_BBOOL.TRUE),
    new CK_ATTRIBUTE(CKA.SENSITIVE, CK_BBOOL.TRUE),
    new CK_ATTRIBUTE(CKA.VALUE_LEN, 32),
    new CK_ATTRIBUTE(CKA.KEY_TYPE, CKK.AES),
    new CK_ATTRIBUTE(CKA.LABEL, "testAES".getBytes()),
    new CK_ATTRIBUTE(CKA.PRIVATE, new CK_BBOOL(bPrivate))
};
CryptokiEx.C_GenerateKey(session, keyGenMech, template, template.length, wrappingKey);

但这给了我一个错误:

C_GenerateKey rv=0x62 - key size range

任何人都可以给我一些想法从这里去解决这个问题..

编辑:只是为了信息 - 我有SafeNet HSM和即时通讯使用Java PKCS#11包装,称为jprovSafeNet ProtectToolkit附带.

我找到了回答new CK_ATTRIBUTE(CKA.VALUE_LEN, 32),,那里的32必须是CK_ULONG值所以当我这样做时:

LongRef l = new LongRef((long)32);

CK_ATTRIBUTE[] template =
{
    new CK_ATTRIBUTE(CKA.CLASS,     CKO.SECRET_KEY),
    new CK_ATTRIBUTE(CKA.TOKEN,     CK_BBOOL.TRUE),
    new CK_ATTRIBUTE(CKA.SENSITIVE, CK_BBOOL.TRUE),
    new CK_ATTRIBUTE(CKA.VALUE_LEN, l.value),
    //new CK_ATTRIBUTE(CKA.VALUE,     key),
    new CK_ATTRIBUTE(CKA.KEY_TYPE,  CKK.AES),
    new CK_ATTRIBUTE(CKA.LABEL,     "testAES".getBytes()),
    new CK_ATTRIBUTE(CKA.PRIVATE,   new CK_BBOOL(bPrivate))
};

在哪里LongRef:

public class LongRef {

    public long value; 

    public LongRef(long l) {
        //compiled code
        throw new RuntimeException("Compiled Code");
    }
}

希望这有助于某人.
