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) = "mysecret!".encrypt(); asserteq!(secret.decrypt(key), "mysecret!"); let (secret, key) = 1234.encrypt(); asserteq!(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:

onewayencrypt:

```rust use secret_msg::SecretMessage;

let cipher = "mysecret!".onewayencrypt(); asserteq!(cipher, "1537"); let cipher = 158721.onewayencrypt(); 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
