現在我想實現通過蟒蛇完全相同的行爲（2.7，如果該事項）。我迄今爲止依靠pycrypto和M2Crypto，但都沒有幫助。

現在雖然上述產生非常相似的輸出，但它不是正確的。爲什麼？因爲當上面的java代碼的輸出被髮送到後端時，我收到一個HTTP 200 OK和期望的響應。

但是，當上面的python代碼的輸出與後端類似地發送時，我收到500內部服務器錯誤，意思是（根據我的假設，考慮到所有其他參數，頭文件等）在java和python HTTP請求之間保持完全一致）後端輸入不正確，因此破壞（再次請忽略500，我同意它應該是更有意義的東西，絕對不是500）

我無權訪問後端。它更像是一個紅色的團隊 - 我們正在做的藍色團隊練習

此外，我可能會調用上面的python代碼，仍然設法達到最終結果並完成工作，但那會是更多的是黑客攻擊，儘管這已經足夠了，但我更感興趣的是知道如何才能夠獨自完成Python。

按下面我的意見提出了一些建議嘗試這樣做，以及：所以，我想這個問題，以及：

from Crypto.Cipher import PKCS1_v1_5 

def encryptMsg(secret): 
    message = secret 
    key = RSA.importKey(open('myPubkey.pem').read()) 
    cipher = PKCS1_v1_5.new(key) 
    ciphertext = b64encode(cipher.encrypt(message)) 
    return ciphertext

，然後在while循環，這樣的：

localStringBuilder1 = localStringBuilder1 + encryptMsg(str(localObject)) + ':::'

仍似乎沒有工作。與以前相同的結果。

響應不看進過多的代碼：在Java中你使用PKCS＃1 V1。 5填充，但在Python中，您沒有使用任何填充。您需要使用'PKCS1_5'類 –

謝謝。說得通。我看到有[https://www.dlitz.net/software/pycrypto/api/2.6/Crypto.Signature.PKCS1_v1_5-module.html] 讓我探索它。 – qre0ct

不..看上去不像上面的鏈接可以提供幫助。有沒有其他的Python庫可以提供這個功能？ – qre0ct
