有没有办法在python中使用DATA_BLOB？

import ctypes
from ctypes import wintypes

# 定义DATA_BLOB结构体
class DATA_BLOB(ctypes.Structure):
    _fields_ = [
        ('cbData', wintypes.DWORD),
        ('pbData', ctypes.POINTER(ctypes.c_char))
    ]

# 加载Crypt32.dll库
crypt32 = ctypes.WinDLL('Crypt32.dll')

# 加密数据
def encrypt_data(data):
    # 将数据转换为bytes类型
    data_bytes = data.encode('utf-8')
    
    # 创建DATA_BLOB对象
    data_blob = DATA_BLOB()
    data_blob.cbData = len(data_bytes)
    data_blob.pbData = ctypes.cast(ctypes.c_char_p(data_bytes), ctypes.POINTER(ctypes.c_char))
    
    # 加密数据
    encrypted_blob = DATA_BLOB()
    crypt32.CryptProtectData(ctypes.byref(data_blob), None, None, None, None, 0, ctypes.byref(encrypted_blob))
    
    # 返回加密后的数据
    return ctypes.string_at(encrypted_blob.pbData, encrypted_blob.cbData)

# 解密数据
def decrypt_data(encrypted_data):
    # 创建DATA_BLOB对象
    encrypted_blob = DATA_BLOB()
    encrypted_blob.cbData = len(encrypted_data)
    encrypted_blob.pbData = ctypes.cast(ctypes.c_char_p(encrypted_data), ctypes.POINTER(ctypes.c_char))
    
    # 解密数据
    decrypted_blob = DATA_BLOB()
    crypt32.CryptUnprotectData(ctypes.byref(encrypted_blob), None, None, None, None, 0, ctypes.byref(decrypted_blob))
    
    # 返回解密后的数据
    return ctypes.string_at(decrypted_blob.pbData, decrypted_blob.cbData).decode('utf-8')

# 测试加密解密功能
data = 'Hello, World!'
encrypted_data = encrypt_data(data)
decrypted_data = decrypt_data(encrypted_data)

print('原始数据:', data)
print('加密后的数据:', encrypted_data)
print('解密后的数据:', decrypted_data)
