Question

我已经使用PyOpenSSL创建了一个连接对象，我已经设法与我正在测试的库建立连接。

我正在使用bio_read和bio_write方法，因为我没有使用套接字来传输数据。

我现在想要将加密的应用程序数据传递给连接对象，并从连接对象中检索未加密的应用程序数据。

这是一个代码snipet来演示我的问题：

# Prints "SSL negotiation finished successfully"
print(conn.state_string());

# I give the connection 37 bytes of data representing encrypted app data
conn.bio_write("\x17\x03\x01...")

# I ask the connection to receive the data written to the buffer
conn.recv(65536)

接下来我用连接对象做什么？我已经尝试过conn.read，但是虽然它存在但是not documented，conn.bio_read会返回一个WantReadError。

感谢您的帮助。

I can't quite remember what I was doing wrong as I am no longer at work, but conn.recv(n) returns the application data. I believe the reason conn.read exists but is undocumented is that the object wraps a socket object, and so this method is a method of the socket and not OpenSSL.SSL.Connection. This would also explain why I receive a read is not a member of NoneType when I call it.
