Simplicity Crypt
================

[](#simplicity-crypt)

A library to encrypt/decrypt your data with two keys and two cipher methods.

Install
-------

[](#install)

**composer**

```
composer require mmdm/sim-crypt
```

Or you can simply download zip file from github and extract it, then put file to your project library and use it like other libraries.

Just add line below to autoload files:

```
require_once 'path_to_library/autoloader.php';
```

and you are good to go.

How to use
----------

[](#how-to-use)

```
// to instance a crypt object
$crypt = new Crypt($main_key, $assured_key);

// to crypt data
$encrypted_message = $crypt->encrypt("message to encrypt");

// to encrypt data
$decrypted_message = $crypt->decrypt($encrypted_message);

// "message to encrypt" will be equal to $decrypted_message at the end
```

### Description

[](#description)

To instantiate crypt object, you need two keys. One is the main key and the other is assured key. These keys must be base64 coded strings. You can build them using [this website](https://mypwd.net/). First generate strong passwords then use base64 encoder/decoder to make them as base64 coded strings and use them for library **or** you can choose two strings as password and use php function `base64_encode()`to make them base64.

Available functions
-------------------

[](#available-functions)

`setFirstEncryptionMethod(string $first_method)`

You can set first encryption method from valid encryption methods. See `openssl_get_cipher_methods()` PHP built-in function for supported methods.

`getFirstEncryptionMethod(): string`

Get first encryption method.

`setSecondEncryptionMethod(string $second_method)`

You can set second encryption method from valid encryption methods. See `openssl_get_cipher_methods()` PHP built-in function for supported methods.

`getSecondEncryptionMethod(): string`

Get second encryption method.

`encrypt($data): ?string`

This method encrypts a message and return encrypted value or `null` if $data is an empty string

```
$encrypted_message = $crypt->encrypt($message_to_encrypt);
```

`decrypt($data): ?string`

This method decrypts an encrypted message and return actual message or `null` if $data is an empty string or an error happened during decode step.

```
$decrypted_message = $crypt->decrypt($encrypted_message);
```

`hasError()`

This function return a boolean indicates operation has error or not.

Note: This method should call after encrypt or decrypt methods to take action on error occurrence.

```
$bool = $crypt->hasError(); // true on having error or false on OK
```
