Ncrypt : A 2-way encryption system

A simple PHP class to encrypt a string, and decrypt an encrypted string

Steps

Include the class

Option 1 (using Composer)

  • Add the following to your composer.json file-
{
    "require": {
        "mukto90/ncrypt": "dev-master"
    }
}
  • Run composer install command.
  • Include your autoloader file (if not already), like this-
include 'vendor/autoload.php';

Option 2

  • Copy class.ncrypt.php file from ncrypt/src/ directory to your project.
  • Include the class in your project file, like this-
include 'src/class.ncrypt.php';

Instantiate the class

$ncrypt = new mukto90\Ncrypt;

Configure (optional)

  • Optionally set secret key, secret IV and cipher
$ncrypt->set_secret_key( '^&-my-key-&^' );  // optional, but STRONGLY recommended
$ncrypt->set_secret_iv( '#@)-my-iv-#*$' );  // optional, but STRONGLY recommended
$ncrypt->set_cipher( 'AES-256-CBC' );       // optional

How to encrypt a plain text/string
