README

Two-way encryption (encrypt and decrypt) data using PHP with OpenSSL

Installation

composer require martinusso/opencrypt

Tips

• $secretKey should have been previously generated in a cryptographically safe way, like openssl_random_pseudo_bytes. OpenCrypt has a static method OpenCrypt::generateKey() for this.

Usage

$password = "OpenCrypt";

// Should have been previously generated in a cryptographically safe way
$secretKey = 'SECRET_KEY';

// You can pass the IV as argument or it is generated automatically
$openCrypt = new OpenCrypt($secretKey [, string $iv ]);

// get the IV
$iv = $openCrypt->iv();

// encrypt
$encryptedPassword = $openCrypt->encrypt($password);
// $encryptedPassword = 'GWw3bqL7FqjmRs0yyIR/8A=='

// decrypt
$decryptedPassword = $openCrypt->decrypt($encryptedPassword);
// $decryptedPassword = 'OpenCrypt'

generate IV

OpenCrypt offers a static method to generate a safe IV:

$iv = OpenCrypt::generateIV();

generate key

it is also possible to generate a safe secret key:

$secretKey = OpenCrypt::generateKey();
