Function Documentation

unsigned int wps_generate_pin

(

void

)

Generate a random PIN.

Returns:

Eight digit PIN (i.e., including the checksum digit)

unsigned int wps_pin_checksum

(

unsigned int

pin

)

Compute PIN checksum.

Parameters:

pin	Seven digit PIN (i.e., eight digit PIN without the checksum digit)

Returns:

Checksum digit

unsigned int wps_pin_valid

(

unsigned int

pin

)

Check whether a PIN has a valid checksum.

Parameters:

pin	Eight digit PIN (i.e., including the checksum digit)

Returns:

1 if checksum digit is valid, or 0 if not
