What is it? #

wrend is a small wireless daemon meant to be minimal, auditable and easy to hack on. It focuses on what most users need at home, without the enterprise and roaming features that make supplicants like wpa_supplicant and iwd large. Deprecated and insecure protocols such as WEP, WPA1/TKIP and WPS are not supported.

The libraries are developed incrementally as features are needed for wrend, if you need a feature simply open a PR, feature requests for libraries will be closed.
