title: what is the equivalent of this in python
body: <p>for a bank transaction implementation, I have a private key and some data and I need to sign that data with the private key. </p>
  
  <p>The example code the bank has given is in C# .NET and I can't find any equivalent to it in python.</p>
  
  <p>The key is in the following format :</p>
  
  <pre><code>&lt;RSAKeyValue&gt;
    &lt;Modulus&gt;...&lt;/Modulus&gt;
    &lt;Exponent&gt;...&lt;/Exponent&gt;
    &lt;P&gt;...&lt;/P&gt;
    &lt;Q&gt;...&lt;/Q&gt;
    &lt;DP&gt;...&lt;/DP&gt;
    &lt;DQ&gt;...&lt;/DQ&gt;
    &lt;InverseQ&gt;...&lt;/InverseQ&gt;
    &lt;D&gt;...&lt;/D&gt;
  &lt;/RSAKeyValue&gt;
  </code></pre>
  
  <p>And the example code is this :</p>
  
  <pre><code>RSACryptoServiceProvider rsa = new RSACryptoServiceProvider();
  rsa.FromXmlString(“ &lt;RSAKeyValue&gt;&lt;Modulus&gt;oQRshGhLf2Fh... ”);
  string data = "#" + merchantCode + "#" + terminalCode + "#"
  +invoiceNumber + "#" + invoiceDate + "#" + amount + "#" +redirectAddress
  + "#" + action + "#" + timeStamp + "#";
  byte[] signMain = rsa.SignData(Encoding.UTF8.GetBytes(data), new
  SHA1CryptoServiceProvider());
  sign = Convert.ToBase64String(signMain);
  </code></pre>
  
  <p>Now I have not found any good equivalent for this in python and I need to do the exact thing in order to not raise any exceptions. I once asked this question in another literature and it got put on hold. I don't know why they did that but I have been struggling this for weeks and I have not yet found any solutions. so please help me in any way you can. thanks in advance.</p>
