.SH DESCRIPTION
\fIbyte_equal\fR returns 1 if the strings are equal, 0 otherwise.
When the strings are different, byte_equal does not read bytes past the
first difference. An attacker observing the execution timing can thus
learn where the first mismatch happened.
Use byte_equal_notimingattack to compare keys, passphrases, cookies or
hashes instead.
