.SH NAME
|
|
byte_equal_notimingattack \- compare two strings
|
|
.SH SYNTAX
|
|
.B #include <libowfat/byte.h>
|
|
|
|
int \fBbyte_equal_notimingattack\fP(const char *\fIone\fR,size_t \fIlen\fR,const char *\fItwo\fR);
|
|
.SH DESCRIPTION
|
|
\fIbyte_equal_notimingattack\fR 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.
