int pbkdf2_sha1	(	const char *	passphrase,

pbkdf2_sha1 - SHA1-based key derivation function (PBKDF2) for IEEE 802.11i : ASCII passphrase : SSID : SSID length in bytes : Number of iterations to run : Buffer for the generated key : Length of the buffer in bytes Returns: 0 on success, -1 of failure

This function is used to derive PSK for WPA-PSK. For this protocol, iterations is set to 4096 and buflen to 32. This function is described in IEEE Std 802.11-2004, Clause H.4. The main construction is from PKCS#5 v2.0.
