Struct IdentityCodex 

pub struct IdentityCodex;

Codex that leaves every byte unchanged.

IdentityCodex is the default Layer 5 implementation. It satisfies the involution requirement trivially (x → x → x) and costs nothing at runtime. Use a non-identity codex when you want the Layer 5 defense; use this one when you are deliberately turning Layer 5 off.

Examples

use key_vault::codex::{Codex, IdentityCodex};

let c = IdentityCodex;
assert_eq!(c.encode(0xab), 0xab);
assert_eq!(c.decode(0xab), 0xab);
