Detailed Description

WPA handshake key integrity and encryption handler.

Note that due to the structure of the 4-Way Handshake we never actually need to encrypt key data, only decrypt it.

Field Documentation

int wpa_kie::version

Value of version bits in EAPOL-Key info field for which to use.

This should be one of the EAPOL_KEY_VERSION_* constants.

void( * wpa_kie::mic) (const void *kck, const void *msg, size_t len, void *mic)

Calculate MIC over message.

Parameters

kck	Key Confirmation Key, 16 bytes
msg	Message to calculate MIC over
len	Number of bytes to calculate MIC over

Return values

mic	Calculated MIC, 16 bytes long

The mic return may point within msg, so it must not be filled until the calculation has been performed.

Definition at line 388 of file wpa.h.

int( * wpa_kie::decrypt) (const void *kek, const void *iv, void *msg, u16 *len)

Decrypt key data.

Parameters

kek	Key Encryption Key, 16 bytes
iv	Initialisation vector for encryption, 16 bytes
msg	Message to decrypt (Key Data field)
len	Length of message

Return values

msg	Decrypted message in place of original
len	Updated to reflect encrypted length
rc	Return status code

The decrypted message is written over the encrypted one.
