Function Documentation

void rsn_pmkid ( const u8 pmk,
size_t  pmk_len,
const u8 aa,
const u8 spa,
u8 pmkid,
int  use_sha256 
)

rsn_pmkid - Calculate PMK identifier : Pairwise master key : Length of pmk in bytes : Authenticator address : Supplicant address : Buffer for PMKID : Whether to use SHA256-based KDF

IEEE Std 802.11i-2004 - 8.5.1.2 Pairwise key hierarchy PMKID = HMAC-SHA1-128(PMK, "PMK Name" || AA || SPA)

const char* wpa_cipher_txt ( int  cipher  ) 

wpa_cipher_txt - Convert cipher suite to a text string : Cipher suite (WPA_CIPHER_* enum) Returns: Pointer to a text string of the cipher suite name

int wpa_eapol_key_mic ( const u8 key,
int  ver,
const u8 buf,
size_t  len,
u8 mic 
)

wpa_eapol_key_mic - Calculate EAPOL-Key MIC : EAPOL-Key Key Confirmation Key (KCK) : Key descriptor version (WPA_KEY_INFO_TYPE_*) : Pointer to the beginning of the EAPOL header (version field) : Length of the EAPOL frame (from EAPOL header to the end of the frame) : Pointer to the buffer to which the EAPOL-Key MIC is written Returns: 0 on success, -1 on failure

Calculate EAPOL-Key MIC for an EAPOL-Key packet. The EAPOL-Key MIC field has to be cleared (all zeroes) when calling this function.

Note: 'IEEE Std 802.11i-2004 - 8.5.2 EAPOL-Key frames' has an error in the description of the Key MIC calculation. It includes packet data from the beginning of the EAPOL-Key header, not EAPOL header. This incorrect change happened during final editing of the standard and the correct behavior is defined in the last draft (IEEE 802.11i/D10).

wpa_pmk_to_ptk - Calculate PTK from PMK, addresses, and nonces : Pairwise master key : Length of PMK : Label to use in derivation : AA or SA : SA or AA : ANonce or SNonce : SNonce or ANonce : Buffer for pairwise transient key : Length of PTK : Whether to use SHA256-based KDF
