这个测试用例使用SKF_Decrypt函数来解密加密的数据，并测试其准确性和TPS性能。在函数中，我们首先获取密钥句柄，然后使用该句柄解密数据。我们还使用print_hex函数来打印输出结果，以便检查解密结果是否正确。在main函数中，我们还使用SKF_Encrypt函数来加密数据，并使用test_skf_decrypt函数来测试SKF_Decrypt函数的性能。

请用C语言帮我写一个关于SKF_Encrypt()函数的测试用例，测试其准确性和TPS性能

好的，以下是一个简单的测试用例：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>
#include "skf.h"

#define TEST_DATA_LEN 1024

int main()
{
    // 初始化加密机
    ULONG rv;
    HAPPLICATION hApp;
    rv = SKF_ConnectDev("ACOS5-64", 0, 0, "", &hApp);
    if (rv != SAR_OK) {
        printf("Failed to connect to device. Error code: %08X\n", rv);
        return -1;
    }

    // 生成测试数据
    BYTE *plainData = (BYTE *)malloc(TEST_DATA_LEN);
    BYTE *cipherData = (BYTE *)malloc(TEST_DATA_LEN);
    BYTE *decryptedData = (BYTE *)malloc(TEST_DATA_LEN);
    if (plainData == NULL || cipherData == NULL || decryptedData == NULL) {
        printf("Failed to allocate memory.\n");
        return -1;
    }
    srand(time(NULL));
    for (int i = 0; i < TEST_DATA_LEN; i++) {
        plainData[i] = rand() % 256;
    }

    // 测试准确性
    ULONG ulDataLen = TEST_DATA_LEN;
    rv = SKF_Encrypt(hApp, plainData, ulDataLen, cipherData, &ulDataLen);
    if (rv != SAR_OK) {
        printf("Failed to encrypt data. Error code: %08X\n", rv);
        return -1;
    }
    rv = SKF_Decrypt(hApp, cipherData, ulDataLen, decryptedData, &ulDataLen);
    if (rv != SAR_OK) {
        printf("Failed to decrypt data. Error code: %08X\n", rv);
        return -1;
    }
    if (memcmp(plainData, decryptedData, TEST_DATA_LEN) != 0) {
        printf("Decrypted data is different from plain data.\n");
        return -1;
    }
    printf("Accuracy test passed.\n");

    // 测试TPS性能
    clock_t start = clock();
    for (int i = 0; i < 100; i++) {
        rv = SKF_Encrypt(hApp, plainData, ulDataLen, cipherData, &ulDataLen);
        if (rv != SAR_OK) {
            printf("Failed to encrypt data. Error code: %08X\n", rv);
            return -1;
        }
    }
    clock_t end = clock();
    double seconds = (double)(end - start) / CLOCKS_PER_SEC;
    printf("TPS: %.2lf\n", 100 / seconds);

    // 释放资源
    free(plainData);
    free(cipherData);
    free(decryptedData);
    SKF_DisconnectDev(hApp);

    return 0;
}

这个测试用例首先连接加密机，并生成一个长度为1024的随机数据作为测试数据。然后它执行了两个测试：

1. 准确性测试：使用SKF_Encrypt函数对测试数据进行加密，然后再使用SKF_Decrypt函数对密文进行解密，最后比较解密后的数据和原始数据是否相同。如果测试通过，则表示SKF_Encrypt函数的准确性正常。
2. TPS性能测试：使用SKF_Encrypt函数对测试数据进行100次加密操作，并计算总共用时。然后将100除以总共用时，得到每秒加密次数。如果每秒加密次数较高，则表示SKF_Encrypt函数的TPS性能较好。

注意：这个测试用例是简单的示范，实际情况下可能需要更复杂的测试用例来覆盖更多的场景和数据。
