## Secret Message

Simple way to encrypt a message (No security whatsoever!!!)

This crate exposes **SecretMessage** trait:

encrypt and decrypt a messge:

**encrypt** and **decrypt**:

```rust
use secret_msg::SecretMessage;

let (secret, key) = "my_secret!".encrypt();
assert_eq!(secret.decrypt(key), "my_secret!");
let (secret, key) = 1234.encrypt();
assert_eq!(secret.decrypt(key), "1234");
```

or use a custom key:

```rust
use secret_msg::SecretMessage;
let secret = "cool secret".encrypt_with_key(58794);
assert_eq!(secret.decrypt(58794), "cool secret");
```
encrypt a message with no easy way to retrieve it back:

**one_way_encrypt**:

```rust
use secret_msg::SecretMessage;

let cipher = "my_secret!".one_way_encrypt();
assert_eq!(cipher, "1537");
let cipher = 158721.one_way_encrypt();
assert_eq!(cipher, "2361");
```

A cli is also provided:

          sm: Secret Message

    Usage: sm enc $file_to_encrypt $encryption_out

    A key will be printed, you can use it to decrypt that message

            sm dec $key $encryption_out

    Example:

            In: sm enc hello_world.txt hello_world.enc
            Out: Key: 1
            In: sm dec 1 hello_world.enc

    Also you can you stdin:

            echo 'hello' | sm enc
            echo 'ifmmp' | sm dec 0
It can even encrypt bin files:

  `cargo r enc img img_enc`
  
  `cargo r dec img_enc img_dec`
