This module uses the OpenSSL library. Some behavior may be platform dependent, since calls are made to the operating system socket APIs. The installed version of OpenSSL may also cause variations in behavior. For example, TLSv1.3 comes with OpenSSL version 1.1.1. Don't use this module without reading the ssl-security. Doing so may lead to a false sense of security, as the default settings of the ssl module are not necessarily appropriate for your application. This section documents the objects and functions in the ssl module; for more general information about TLS, SSL, and certificates, the reader is referred to the documents in the "See Also" section at the bottom. This module provides a class, ssl.SSLSocket, which is derived from the socket.socket type, and provides a socket-like wrapper that also encrypts and decrypts the data going over the socket with SSL. It supports additional methods such as getpeercert, which retrieves the certificate of the other side of the connection, cipher, which retrieves the cipher being used for the secure connection or get_verified_chain, get_unverified_chain which retrieves certificate chain. For more sophisticated applications, the ssl.SSLContext class helps manage settings and certificates, which can then be inherited by SSL sockets created through the SSLContext.wrap_socket method. Updated to support linking with OpenSSL 1.1.0 OpenSSL 0.9.8, 1.0.0 and 1.0.1 are deprecated and no longer supported. In the future the ssl module will require at least OpenSSL 1.0.2 or 1.1.0. 644 has been implemented. The ssl module requires OpenSSL 1.1.1 or newer. Use of deprecated constants and functions result in deprecation warnings. Attribution: Adapted from Python Documentation under PSF-2.0.
