This is an Order-preserving encryption (OPE) lib inspired by cryptdb's ope implementation.
It is a pure rust implementation, no c dependencies needed.
It is also written for no-std targets (thanks to num-traits) and works in wasm.
The max value to encrypt is 65532
use ope::get_ope;
fn main()
{
let k = b"this is a key 10".to_owned();
let ope = get_ope(&k);
let a = ope.encrypt(21).unwrap();
let b = ope.encrypt(65531).unwrap();
let c = ope.encrypt(65532).unwrap();
assert!(a < b);
assert!(b < c);
}
