ralph
=====

[](#ralph)

A semi-secure symmetric encryption library that sometimes eats crayons.

Ralph provides acceptable security in situations where size is critical. All major security parameters are 64 bit (block, iv and checksum). As a result, input strings under 8 bytes long result in a 24 byte cypher text.

```
$encrypted = ralph()::encrypt('secret', 'password');

var_dump(base64_encode($encrypted));
#string(32) "M783Db84XVPukJZkRh05R5ZBZxcD4CvM"

$decrypted = ralph()::decrypt($encrypted, 'password');

var_dump($decrypted);
#string(6) "secret"
```

Ralph isn't very smart, so he registers himself the in global namespace `\Ralph`. He also registers the global helper function `ralph()`, for your convenience and amusement.

install
-------

[](#install)

**EXPERIMENTAL**

Ralph is compatible with PHP versions 7.1 to 8.1.

```
composer require mmeyerk/ralph main-dev
```

how it works
------------

[](#how-it-works)

Ralph uses `hash_pbkdf2()` to generate a key stream which is then XORed with the message. Both `encrypt` and `decrypt` functions accept an optional third parameter to specify iterations for key hardening.

```
$iterations = 10000;
$encrypted = ralph()::encrypt('secret', 'password', $iterations);
$decrypted = ralph()::decrypt($encrypted, 'password', $iterations);
```

specs
-----

[](#specs)

- initialization vector (`random_bytes`)
- time-safe checksum verification (`hash_equals`, `hash_hmac`, `sha3-256`)
- block padding (`PKCS#7`)
- key stream generation (`hash_pbkdf2`, `sha3-512`)
