NAME¶

byte_equal_notimingattack - compare two strings

SYNTAX¶

#include <libowfat/byte.h>

int byte_equal_notimingattack(const char *one,size_t len,const char *two);

DESCRIPTION¶

byte_equal_notimingattack returns 1 if the strings are equal, 0 otherwise.

When the strings are different, byte_equal_notimingattack will still read and compare all the other bytes. That way, an attacker observing the timing of the execution can not learn where the first mismatch occurred.
