pskc_get_key_data_timedrift — API function

Synopsis

#include <pskc.h>

uint32_t pskc_get_key_data_timedrift(pskc_key_t * key, int * present);

Arguments

pskc_key_t * key

a pskc_key_t handle, from pskc_get_keypackage().

int * present

output variable indicating whether data was provided or not.

Description

Get the PSKC KeyPackage Key Data TimeDrift value.  This element contains the device clock drift value for time-based OTP algorithms.  The integer value (positive or negative drift) that indicates the number of time intervals that a validation server has established the device clock drifted after the last successful authentication.  So, for example, if the last successful authentication established a device time value of 8 intervals from a specific start date but the validation server determines the time value at 9 intervals, the server SHOULD record the drift as -1.

If present is non-NULL, it will be 0 if the field is not present or 1 if it was present.

Returns

an integer holding the content.
