README

A php library to encrypt and decrypt strings with dynamic keys. This was be implemented to guarantee a quite high security level.

The dynamic key is based on a substring of the hash of the passPhrase. The position of the first char of the key is saved in the end of the encrypted string to revert the encryption process. Because of the random substring, every encrypted string will be different from the previous one.

Install

Before using Dynamic Crypto in your project, add it to your "composer.json" file:

{
    "require": {
        "testinaweb/dynamic-crypto": "1.0.*@dev"
    }
}

or run this command as a bash command:

./composer.phar require testinaweb/dynamic-crypto 1.0.*@dev

Usage

<?php

use DynamicCrypto\DynamicCryptoFactory;

$passPhrase = 'ILoveDC';
$input = 'Your string here';

$dynamicEncrypt = DynamicCryptoFactory::buildDynamicEncrypter($passPhrase);
$dynamicDecrypt = DynamicCryptoFactory::buildDynamicDecrypter($passPhrase);

$encryptedString = $dynamicEncrypt->encrypt($input);
$decryptedString = $dynamicDecrypt->decrypt($encryptedString);
