HSM 生成自签名证书报告 "wrapping key handle invalid" 错误

Question

使用 HSM（使用 PKCS11 标准 API）生成自签名证书报告 "wrapping key handle invalid" 错误（错误代码 113、CKR_WRAPPING_KEY_HANDLE_INVALID）。当使用 GUI ctbrowser 工具生成或使用类似于他们的演示的代码时，都会发生这种情况。

这里是一个重现问题的代码示例，它生成一个 RSA 密钥对，然后尝试用它们生成一个自签名证书。

int main()
{
    int rv;
    CK_CHAR pwd[] = "password";
    static char pubkeyLabel[256]="demoPub";
    static char prvkeyLabel[256]="demoPrv";
    static CK_BYTE id[256];
    static CK_BBOOL isTok = TRUE;
    static CK_BBOOL True = TRUE;
    static CK_BBOOL False = FALSE;

    CK_SESSION_HANDLE hSession;
    CK_OBJECT_HANDLE hPubKey;
    CK_OBJECT_HANDLE_PTR phPubKey = &hPubKey;
    CK_OBJECT_HANDLE hSignerKey;
    CK_OBJECT_HANDLE_PTR phSignerKey = &hSignerKey;
    CK_OBJECT_HANDLE hCert;
    CK_OBJECT_HANDLE_PTR phCert = &hCert;
    CK_MECHANISM mechanism = { 0, NULL, 0 };
    static CK_SIZE mBits=2048;

    static char edate[] = {'2','0','2','0','1','2','3','1'};
    static char certLabel[128]="demo_cert";
    static char subject[256]="C=XX,ST=XX,L=XX,O=MEOW,OU=HSM,CN=TESTCERT";

    CK_ATTRIBUTE publicKeyTemplate[] = {
      {CKA_TOKEN, &isTok, 1},
      {CKA_PRIVATE, &False, 1},
      {CKA_LABEL, pubkeyLabel, sizeof(pubkeyLabel)},
      {CKA_SUBJECT_STR, subject, sizeof(subject)},
      {CKA_MODULUS_BITS, &mBits, sizeof(mBits)},
      {CKA_ENCRYPT, &False, 1},
      {CKA_VERIFY, &True, 1},
      {CKA_WRAP, &False, 1},
      {CKA_DERIVE, &True, 1},
      {CKA_EXTRACTABLE, &True, 1},
      {CKA_EXPORTABLE, &True, 1}
    };
    CK_ATTRIBUTE privateKeyTemplate[] = {
      {CKA_TOKEN, &isTok, 1},
      {CKA_LABEL, prvkeyLabel, sizeof(prvkeyLabel)},
      {CKA_PRIVATE, &True, 1},
      {CKA_SUBJECT_STR, subject, sizeof(subject)},
      {CKA_ID, id, sizeof(id)},
      {CKA_SENSITIVE, &True, 1},
      {CKA_DECRYPT, &False, 1},
      {CKA_SIGN, &True, 1},
      {CKA_UNWRAP, &True, 1},
      {CKA_WRAP, &False, 1},
      {CKA_EXTRACTABLE, &False, 1},
      {CKA_EXPORTABLE, &False, 1}
    };

    CK_ATTRIBUTE certTemplate[] = {
      {CKA_TOKEN, &True, 1},
      {CKA_PRIVATE, &False, 1},
      {CKA_LABEL, certLabel, sizeof(certLabel)},
      {CKA_SUBJECT_STR, subject, sizeof(subject)},
      {CKA_ISSUER_STR, subject, sizeof(subject)},
      {CKA_END_DATE, edate, sizeof(edate)},
      {CKA_EXTRACTABLE, &True, 1},
      {CKA_EXPORTABLE, &True, 1}
    };

    printf("Generate cert %s from %s, signed by %s.\n", certLabel, pubkeyLabel, prvkeyLabel);
    rv = C_Initialize(NULL_PTR);
    if ( rv ) return rv;

    rv = C_OpenSession(0, CKF_RW_SESSION|CKF_SERIAL_SESSION, NULL, NULL, &hSession);

    rv = C_Login(hSession, CKU_USER, pwd, 8);

    publicKeyTemplate[2].valueLen = (CK_SIZE)strlen((char*)pubkeyLabel);
    publicKeyTemplate[3].valueLen = (CK_SIZE)strlen((char*)subject)+1;
    privateKeyTemplate[1].valueLen = (CK_SIZE)strlen((char*)prvkeyLabel);
    privateKeyTemplate[3].valueLen = (CK_SIZE)strlen((char*)subject)+1;
    mechanism.mechanism = CKM_RSA_PKCS_KEY_PAIR_GEN;
    rv = C_GenerateKeyPair(hSession, &mechanism,
                           publicKeyTemplate, NUMITEMS(publicKeyTemplate),
                           privateKeyTemplate, NUMITEMS(privateKeyTemplate),
                           phPubKey, phSignerKey);
    printf("Keypair generated with rv=%x\n", rv);

    mechanism.mechanism = CKM_SHA256_RSA_PKCS;
    rv = C_SignInit(hSession, &mechanism, hSignerKey);
    printf("cert signer initiated with rv=%x\n", rv);
    mechanism.mechanism = CKM_ENCODE_X_509;
    certTemplate[2].valueLen = (CK_SIZE)strlen((char*)certLabel);
    certTemplate[3].valueLen = (CK_SIZE)strlen((char*)subject)+1;
    certTemplate[4].valueLen = (CK_SIZE)strlen((char*)subject)+1;
    rv = C_DeriveKey(hSession, &mechanism,
                     hPubKey,
                     certTemplate, NUMITEMS(certTemplate),
                     phCert);
    printf("cert generation finished with rv=%x\n", rv);

    return 0;
}

由于整个过程不涉及任何包装，我不知道如何调试它。有谁知道它有什么问题吗？（注意：插槽已预先存在并已初始化。）

Answer 1

因此，要么将 CKA_USAGE_COUNT 添加到签名密钥，要么通过在证书模板中指示 CKA_SERIAL_NUMBER/CKA_SERIAL_NUMBER_INT 来指示证书的序列号将解决问题。
