以下是可以实现将证书加载到 pkcs11 中的示例代码。请注意,这段代码仅供参考,具体实现可能需要根据实际情况进行修改和调整。
```
#include <stdio.h>
#include <openssl/engine.h>
#include <openssl/pkcs11.h>
int main() {
// 初始化 OpenSSL 库
ENGINE_load_builtin_engines();
ENGINE_register_all_complete();
// 获取 pkcs11 引擎
ENGINE *e = ENGINE_by_id("pkcs11");
if (e == NULL) {
printf("ERROR: Failed to get pkcs11 engine\n");
return -1;
}
// 初始化 pkcs11 引擎
if (!ENGINE_init(e)) {
printf("ERROR: Failed to initialize pkcs11 engine\n");
ENGINE_free(e);
return -1;
}
// 获取 pkcs11 引擎提供的函数
const PKCS11_FUNCTIONS *pkcs11 = ENGINE_get_pkcs11(e);
if (pkcs11 == NULL) {
printf("ERROR: Failed to get pkcs11 functions\n");
ENGINE_free(e);
return -1;
}
// 初始化 pkcs11
CK_C_GetFunctionList pGetFunctionList = pkcs11->C_GetFunctionList;
CK_FUNCTION_LIST_PTR pFunctionList;
CK_RV rv = pGetFunctionList(&pFunctionList);
if (rv != CKR_OK) {
printf("ERROR: Failed to initialize pkcs11\n");
ENGINE_free(e);
return -1;
}
// 获取默认的 pkcs11 slot
CK_SLOT_ID slotId;
rv = pkcs11->C_GetSlotList(CK_TRUE, &slotId, NULL);
if (rv != CKR_OK) {
printf("ERROR: Failed to get pkcs11 slot\n");
ENGINE_free(e);
return -1;
}
// 打开 pkcs11 token
CK_SESSION_HANDLE sessionHandle;
CK_FLAGS flags = CKF_SERIAL_SESSION | CKF_RW_SESSION;
rv = pkcs11->C_OpenSession(slotId, flags, NULL, NULL, &sessionHandle);
if (rv != CKR_OK) {
printf("ERROR: Failed to open pkcs11 session\n");
ENGINE_free(e);
return -1;
}
// 读取证书
FILE *file = fopen("/home/ts/cert.pem", "r");
if (file == NULL) {
printf("ERROR: Failed to open cert file\n");
ENGINE_free(e);
pkcs11->C_CloseSession(sessionHandle);
return -1;
}
X509 *cert = PEM_read_X509(file, NULL, NULL, NULL);
fclose(file);
if (cert == NULL) {
printf("ERROR: Failed to read cert file\n");
ENGINE_free(e);
pkcs11->C_CloseSession(sessionHandle);
return -1;
}
// 将证书加载到 pkcs11 中
CK_OBJECT_HANDLE certHandle;
CK_ULONG certLen = i2d_X509(cert, NULL);
unsigned char *certData = (unsigned char *)malloc(certLen);
i2d_X509(cert, &certData);
CK_ATTRIBUTE certAttr[] = {
{CKA_CLASS, &certType, sizeof(certType)},
{CKA_TOKEN, &trueVal, sizeof(trueVal)},
{CKA_PRIVATE, &falseVal, sizeof(falseVal)},
{CKA_LABEL, "MyCertificate", sizeof("MyCertificate")},
{CKA_VALUE, certData, certLen}
};
rv = pkcs11->C_CreateObject(sessionHandle, certAttr, 5, &certHandle);
if (rv != CKR_OK) {
printf("ERROR: Failed to load cert to pkcs11\n");
ENGINE_free(e);
pkcs11->C_CloseSession(sessionHandle);
return -1;
}
// 释放资源
ENGINE_free(e);
pkcs11->C_CloseSession(sessionHandle);
X509_free(cert);
free(certData);
return 0;
}
```
上述代码中,我们首先获取 pkcs11 引擎,并初始化该引擎。然后,我们获取 pkcs11 引擎提供的函数,并使用这些函数初始化 pkcs11。接着,我们打开 pkcs11 token,并读取要加载的证书文件。最后,我们将证书加载到 pkcs11 中,并释放相关资源。
