CNG SSL提供者函数的调用方式？

在Windows中使用CNG（Cryptographic Next Generation）的SSL提供程序进行加密和解密操作时，可以使用一组提供者函数来进行管理和实现加密和解密。

以下是使用CNG SSL提供程序函数进行加密和解密的示例代码：

#include <windows.h>
#include <wincrypt.h>

#define SSL_CIPHER_SUITES "TLS_RSA_WITH_RC4_128_MD5"

void encryptData(PBYTE data, DWORD dataSize, LPBYTE encryptedData, DWORD* encryptedDataSize)
{
    DWORD status = 0;
    NCRYPT_PROV_HANDLE providerHandle;
    NCRYPT_KEY_HANDLE keyHandle;
    NCryptBuffer cipherSuites[] = {
        { sizeof(SSL_CIPHER_SUITES), NCRYPT_SSL_CIPHER_SUITE, SSL_CIPHER_SUITES },
        { 0, 0, 0 },
    };
    NCryptBufferDesc desc = { NCRYPTBUFFER_SSL_CIPHERSUITES, cipherSuites };

    // Open the SSL provider handle
    status = NCryptOpenStorageProvider(&providerHandle, MS_SSL_PROVIDER, 0);
    if (status != ERROR_SUCCESS)
        return;

    // Import the SSL key
    status = NCryptImportKey(providerHandle, NULL, NCRYPT_CIPHER_KEY_BLOB, NULL, &keyHandle, data, dataSize, 0);
    if (status != ERROR_SUCCESS)
    {
        NCryptFreeObject(providerHandle);
        return;
    }

    // Encrypt the data
    status = NCryptEncrypt(keyHandle, NULL, (PBYTE)data, dataSize, NULL, 0, encryptedData, *encryptedDataSize, encryptedDataSize, NCRYPT_SSL_FLAGS);
    if (status != ERROR_SUCCESS)
        printf("Encryption failed");

    // Cleanup
    NCryptDeleteKey(keyHandle, 0);
    NCryptFreeObject(providerHandle);
}

void decryptData(PBYTE encryptedData, DWORD encryptedDataSize, LPBYTE decryptedData, DWORD* decryptedDataSize)
{
    DWORD status = 0;
    NCRYPT_PROV_HANDLE providerHandle;
    NCRYPT_KEY_HANDLE keyHandle;
    NCryptBuffer cipherSuites[] = {
        { sizeof(SSL_CIPHER_SUITES), NCRYPT_SSL
