-# ussl – SSL/TLS module
+# ussl – SSL/TLS 模块
 
 This module implements a subset of the corresponding* [`CPython`](http://docs.micropython.org/en/latest/reference/glossary.html#term-cpython) *module, as described below. For more information, refer to the original CPython documentation: [`ssl`](https://docs.python.org/3.5/library/ssl.html#module-ssl).
 
 This module provides access to Transport Layer Security (previously and widely known as “Secure Sockets Layer”) encryption and peer authentication facilities for network sockets, both client-side and server-side.
 
-## Functions
+## 功能函数
 
-- `ussl.``wrap_socket`(sock, server_side=False, keyfile=None, certfile=None, cert_reqs=CERT_NONE, ca_certs=None)
+- `ussl.wrap_socket`(sock, server_side=False, keyfile=None, certfile=None, cert_reqs=CERT_NONE, ca_certs=None)
 
-  Takes a [`stream`](http://docs.micropython.org/en/latest/reference/glossary.html#term-stream) *sock* (usually usocket.socket instance of `SOCK_STREAM` type), and returns an instance of ssl.SSLSocket, which wraps the underlying stream in an SSL context. Returned object has the usual [`stream`](http://docs.micropython.org/en/latest/reference/glossary.html#term-stream) interface methods like `read()`, `write()`, etc. In MicroPython, the returned object does not expose socket interface and methods like `recv()`, `send()`. In particular, a server-side SSL socket should be created from a normal socket returned from[`accept()`](http://docs.micropython.org/en/latest/library/usocket.html#usocket.socket.accept) on a non-SSL listening server socket.Depending on the underlying module implementation in a particular [`MicroPython port`](http://docs.micropython.org/en/latest/reference/glossary.html#term-micropython-port), some or all keyword arguments above may be not supported.

 Warning: Some implementations of `ussl` module do NOT validate server certificates, which makes an SSL connection established prone to man-in-the-middle attacks.
