redis-py is the second Redis client that natively supported SSL. Use the SSLConnection class or simply instantiate your connection pool using a rediss://-URL and the from_url method, like so:
r = redis.Redis( url='rediss://:password@hostname:port/0',
password='password',
ssl_keyfile='path_to_keyfile',
ssl_certfile='path_to_certfile',
ssl_cert_reqs='required',
ssl_ca_certs='path_to_ca_cert')
