ope

This code implements the OPE algorithm. It is based on the following work:

Order-Preserving Symmetric Encryption
Boldyreva, 2009

running

When run the following code is run:

    // pass OPE the key
    let mut ope = ope::OPE::new(String::from("my secret key"));

    let a = ope.encrypt(1529939373);
    let b = ope.encrypt(1529939377);
    let c = ope.encrypt(1529939378);

    println!("a: {}, b: {}, c: {}", a, b, c);
    assert!(a < b);
    assert!(b < c);

Seen above, we initialize the OPE with a secret key, then encrypt three ascending numbers. We then print the results out and check that order has been preserved across the numbers.

Below is the output of this program:

a: 4294961016, b: 4294961545, c: 4294965783
