使用Bytes[]将PythonNet转换为PythonNet

Question

我有一个PythonNet C# bytes[]对象，我需要将它转换为Python的bytes。

有什么方法可以使用Python来完成这个任务吗？

下面是我要做的来获取字节。我需要进入酿酒厂的凭证商店并导出客户证书。

import clr, os
import requests

from cryptography.hazmat.primitives.serialization.pkcs12 import (
    load_key_and_certificates,
)
from cryptography.hazmat.primitives.serialization import Encoding, NoEncryption
from cryptography.hazmat.backends import default_backend



clr.AddReference("System")
clr.AddReference("System.Security.Cryptography.X509Certificates")
clr.AddReference("System.Security.Cryptography")

from System.Security.Cryptography.X509Certificates import (
    X509Store,
    StoreName,
    StoreLocation,
    OpenFlags,
    X509CertificateCollection,
    X509FindType,
    X509Certificate2,
    X509ContentType,
)

store = X509Store(StoreName.My, StoreLocation.CurrentUser)
store.Open(OpenFlags.ReadOnly)

serial_number = (
    'SUPER SECRET SERIAL NUMBER'  
)

collection = store.Certificates.Find(
    X509FindType.FindBySerialNumber, serial_number, False
)
cert = collection.get_Item(0)
pkcs12 = cert.Export(X509ContentType.Pkcs12, "<Secret Password>")
# I have System.Bytes[] need python bytes to use with pyopenssl/cryptography

此代码使用pythonnet库访问windows上的密码API。然后，它将由序列号找到的客户端证书转储为字节。当clr库返回值时，它就是一个system.Bytes[]。这与其他库不兼容，因此我需要一种将该对象转换为Python字节的方法。

您应该能够使用bytes函数(正如@JabberJabber所提到的那样)。以下内容适用于我(c_sharp_bytes实际上是C#函数的结果)和Python3.8：

from System import Byte, Array
python_bytes = b'Some bytes'

# Python -> C#
c_sharp_bytes = Array[Byte](python_bytes)  # <System.Byte[] object at 0x000001A33CC2A3D0>

# C# -> Python
python_bytes = bytes(c_sharp_bytes)  # b'Some bytes'
