Crate sqep 

SQEP Core Library

• Default build: exposes SQEP Lite (MIT licensed).
• plus feature: adds SQEP Plus, Hybrid (KEM+HKDF+AEAD), and optional Firewall helpers.

Example (Lite):

use sqep::prelude::*;
let cipher = ZeroshieldCipher::new();

Example (Plus + Hybrid):

use sqep::prelude::*;
use sqep::{Kem, KemImpl};

let sqep = SQEPPlus::new();

let kp = KemImpl::keypair();
let aad = b"route=vpn;tenant=elevitax";
let (blob, _meta) = sqep.encrypt_plus_hybrid(&kp.pk, b"secret payload", aad);

let recv = SQEPPlus::new();
let pt = recv.decrypt_plus_hybrid(&kp.sk, &blob, aad).unwrap();

assert_eq!(&pt, b"secret payload");
