java - HSM AES key 提取

Question

我有一个 Thales nShield HSM，其中创建了一个(CKA_SENSATIVE，假)AES key ，我想提取该 key ，但是我根本不知道如何在 java 中执行此操作。我的 key 创建如下所示:

CK_ATTRIBUTE[] aesKeyObject = new CK_ATTRIBUTE[14];

    try
    {
        aesKeyObject[0] = new CK_ATTRIBUTE(CKA_CLASS, CKO_SECRET_KEY);
        aesKeyObject[1] = new CK_ATTRIBUTE(CKA_KEY_TYPE, CKK_AES);
        aesKeyObject[2] = new CK_ATTRIBUTE(CKA_VALUE_LEN, 32);
        aesKeyObject[3] = new CK_ATTRIBUTE(CKA_TOKEN, true);
        aesKeyObject[4] = new CK_ATTRIBUTE(CKA_LABEL, "TestAES".getBytes());
        aesKeyObject[5] = new CK_ATTRIBUTE(CKA_PRIVATE, true);
        aesKeyObject[6] = new CK_ATTRIBUTE(CKA_EXTRACTABLE, true);
        aesKeyObject[7] = new CK_ATTRIBUTE(CKA_WRAP, true);
        aesKeyObject[8] = new CK_ATTRIBUTE(CKA_UNWRAP, true);
        aesKeyObject[9] = new CK_ATTRIBUTE(CKA_ENCRYPT, true);
        aesKeyObject[10] = new CK_ATTRIBUTE(CKA_DECRYPT, true);
        aesKeyObject[11] = new CK_ATTRIBUTE(CKA_TRUSTED, true);
        aesKeyObject[12] = new CK_ATTRIBUTE(CKA_ID, 1550);
        aesKeyObject[13] = new CK_ATTRIBUTE(CKA_SENSITIVE, false);

        CK_MECHANISM mech = new CK_MECHANISM(CKM_AES_KEY_GEN);

        long newAESKeyHandle = p11.C_GenerateKey(hSession, mech, aesKeyObject);     
    }catch(Exception e)
    {
    }

您需要使用C_GetAttributeValue函数读取生成的 key 对象的CKA_VALUE属性。
