Function constant_time_eq::constant_time_eq_n

pub fn constant_time_eq_n<const N: usize>(a: &[u8; N], b: &[u8; N]) -> bool

Compares two fixed-size byte strings in constant time.

Examples

use constant_time_eq::constant_time_eq_n;

assert!(constant_time_eq_n(&[3; 20], &[3; 20]));
assert!(!constant_time_eq_n(&[3; 20], &[7; 20]));
