Examples

Encrypt

using sweecrypt::encode;

fn main() {
    println!("{}", encode("hello, world!", 0));
}

$ sweecrypt encrypt "hello, world!"
!?~~(:,}(>~/a

Decrypt

using sweecrypt::decode; 

fn main() {
    println!("{}", decode("!?~~(:,}(>~/a", 0));       
}

$ sweecrypt decrypt '!?~~(:,}(>~/a'
hello, world!

Shifting DB

using sweecrypt::{decode,encode};

fn main() {
    let encoded = encode("hello, world!", 3);
    println!("{}", encoded);
    println!("{}", decode(encoded, 3)); // Correct output
    println!("{}", decode(encoded, 0)); // Wrong output
}

$ sweecrypt encrypt --shift 3 "hello, world"
\!((>ba_>](#
$ sweecrypt decrypt --shift 3 "\!((>ba_>](#"
hello, world

It will output a nonsense string if shifted incorrectly.

$ sweecrypt decrypt "\!((>ba_>](#"
