python - 如何在Python中实现类似C# RSACryptoServiceProvider的加密？

Question

所以，在 C# 中我有以下代码:

public static void Main (string[] args)
{
    publicKeyXml = "<Modulus>mFCubVhPGG+euHuVQbNObqod/Ji0kRe+oh2OCFR7aV09xYiOklqFQ8jgIgAHvyCcM1JowqfFeJ5jV9up0Lh0eIiv3FPRu14aQS35kMdBLMebSW2DNBkfVsOF3l498WWQS9/THIqIaxbqwRDUxba5btBLTN0/A2y6WWiXl05Xu1c=</Modulus><Exponent>AQAB</Exponent>";
    RSACryptoServiceProvider rSACryptoServiceProvider = new RSACryptoServiceProvider ();
    rSACryptoServiceProvider.FromXmlString (publicKeyXml);
    Console.WriteLine(Convert.ToBase64String (rSACryptoServiceProvider.Encrypt (Encoding.ASCII.GetBytes(args[0]), false)));
}

当我用来加密消息时，它在远程服务器上运行得很好(我没有源代码)。但是，当尝试使用 PyCrypto 在 Python 中执行类似操作时，远程服务器无法解密。

from Crypto.PublicKey import RSA
from Crypto.Cipher import PKCS1_v1_5

KEY = RSA.importKey(open('login.key').read()) # Converted to standard format
KEY_CIPHER = PKCS1_v1_5.new(KEY)

testmsg = KEY_CIPHER.encrypt("test msg").encode('base64').replace('\n', '')
# send testmsg down a socket
# Response: {"info":"java.lang.IllegalArgumentException: Could not decrypt.","msg":"Fail"}

对于为什么会出现这种情况有什么想法吗？

好吧，就我而言，这很奇怪。服务器端正在期待我的东西向后。为了解决这个问题，我简单地这样做了:

from Crypto.PublicKey import RSA
from Crypto.Cipher import PKCS1_v1_5

KEY = RSA.importKey(open('login.key').read()) # Converted to standard format
KEY_CIPHER = PKCS1_v1_5.new(KEY)

testmsg = KEY_CIPHER.encrypt("test msg").encode('base64').replace('\n', '')
testmsg = "".join(reversed([testmsg[i:i+2] for i in range(0, len(testmsg), 2)]))
