Sample hostapd.conf for documentation.

##### hostapd configuration file ##############################################
# Empty lines and lines starting with # are ignored
# AP netdevice name (without 'ap' postfix, i.e., wlan0 uses wlan0ap for
# management frames with the Host AP driver); wlan0 with many nl80211 drivers
interface=wlan0
# In case of atheros and nl80211 driver interfaces, an additional
# configuration parameter, bridge, may be used to notify hostapd if the
# interface is included in a bridge. This parameter is not used with Host AP

"""Basic Python Cheat Sheet by Filip Kral on 2015/02/16"""
"""
Python is a cross-platform, interpreted, object-oriented programming language.
That means you can run it on Linux, Windows, Mac, and other platforms,
you don't need to compile your code to execute it because it is compiled on
the fly, and you can use classes and objects.

Symmetric Encryption

The only way to encrypt today is authenticated encryption, or "AEAD". ChaCha20-Poly1305 is faster in software than AES-GCM. AES-GCM will be faster than ChaCha20-Poly1305 with AES-NI. Poly1305 is also easier than GCM for library designers to implement safely. AES-GCM is the industry standard.

Use, in order of preference:

  1. The NaCl/libsodium default
