# NAME

`ieee80211_crypto_attach`, `ieee80211_crypto_detach`, `ieee80211_crypto_encap` —
802.11 WEP encryption functions

# SYNOPSIS

void
`ieee80211_crypto_attach`(struct ieee80211com *ic);

void
`ieee80211_crypto_detach`(struct ieee80211com *ic);

struct ieee80211_key *
`ieee80211_crypto_encap`(struct ieee80211com *ic, struct ieee80211_node *ni, struct mbuf *m0);

# DESCRIPTION

These functions provide encryption support for 802.11 device drivers.

The `ieee80211_crypto_attach`() function initializes crypto support for the interface ic. The default is null crypto.

The `ieee80211_crypto_detach`() function frees data structures associated with crypto support for the interface ic.

The two above functions are automatically called by the interface attach and detach routines, respectively.

The `ieee80211_crypto_encap`() function encapsulates the packet supplied in mbuf m0, with the crypto headers given the for node ni. Software encryption is possibly performed. In case of no specified key for ni or multicast traffic, the default key for the interface ic is used for encapsulation. The key is returned in the case of successful encapsulation, otherwise `NULL` is returned.
