About
-----

[](#about)

This is a cryptography library for PHP 7. It's based on [OpenSSL](http://php.net/manual/en/book.openssl.php) and provides the following features:

- Symmetric encryption and authentication (AES + HMAC-SHA256 as default);
- Public Key cryptography (management keys, encryption/decryption)
- Hybrid encryption using symmetric and public key ([OpenPGP](http://www.ietf.org/rfc/rfc4880.txt) like)

Version
-------

[](#version)

As this software is **ALPHA, Use at your own risk!**

Usage
-----

[](#usage)

The usage is quite straightforward, after installing the library using composer:

```
composer require ezimuel/phpcrypto:dev-master

```

You can consume the following classes Symmetric, PublicKey and Hybrid for symmetric encryption, public key and hybrid encryption.

For instance, if you want to encrypt a string in a symmetric way, you can use the following code:

```
use PHPCrypto\Symmetric;

$plaintext = 'Text to encrypt';
$key = '123456789012'; // This can be also a user's password we generate a new
                       // one for encryption using PBKDF2 algorithm

$cipher = new Symmetric(); // AES + HMAC-SHA256 by default
$cipher->setKey($key);
$ciphertext = $cipher->encrypt($plaintext);

// or passing the $key as optional paramter
// $ciphertext = $cipher->encrypt($plaintext, $key);

$result = $cipher->decrypt($ciphertext);

// or passing the $key as optional paramter
// $result = $cipher->decrypt($ciphertext, $key);

print ($result === $plaintext) ? "OK" : "FAILURE";
```

SECURITY BEST PRACTICES
-----------------------

[](#security-best-practices)

In this project we used the following security best practices:

- Min size of user's key for encryption set to 12

    Source: [https://en.wikipedia.org/wiki/Password\_strength](https://en.wikipedia.org/wiki/Password_strength)
- Use of PBKDF2 to generate the encryption and authentication key. Set the default iteration number to 80'000 (min 20'000)

    Source:
- Encryption-then-authentication using HMAC

    Source:
- Use of OAEP padding for OpenSSL public key encryption

TO DO
-----

[](#to-do)

- encrypt/decrypt functions in PublicKey
- sign/verify functions for digital signature in PublicKey
- support multiple keys in Hybrid schema
- Ca management in public key schemas

NOTES ABOUT OPENSSL EXTENSION
-----------------------------

[](#notes-about-openssl-extension)

Here I reported some notes about the OpenSSL PHP extension usage:

- it will be nice to have the **openssl\_cipher\_key\_size()** function to get the key size of the specific cipher choosen;
