Installation

Install with Composer:

composer require tankfairies/tcrypt 

Usage

Instantiate a copied of Keys for handing local key pairs.

$keys = new Keys();
$keys->setPasswordAndSalt('senders_password', 'a_custom_salt_at_least_15_chars_long');
$thePublicSenderKey = $keys->getPublicKey();

$keys = new Keys();
$keys->setPasswordAndSalt('receivers_password', 'a_custom_salt_at_least_15_chars_long');
$thePublicReceiverKey = $keys->getPublicKey();

Example of a generated public key

a322e905bd29167702bfc816a6e5ad2be0d8ede171d3c6e68497a5ef5b316d08

Encrypt the message: -

$crypt = new Encrypt();
$crypt
    ->setLocalKeys($sendKeys)
    ->setForeignKey($thePublicReceiverKey);

$encryptedMessage = $crypt->enc('my secret message');

This will produce something like: -

9G/vMg4piI778CzVpjcOL/c4kGV7+j0ih+JfuYh0QzWYyfAvwQcy1tW8jXcrb2Fd5aRvkljTeQ55

To Decrypt the message: -

$decrypt = new Decrypt();
$decrypt
    ->setLocalKeys($keys)
    ->setForeignKey($thePublicSenderKey);

$decryptedMessage = $decrypt->dec($encryptedMessage);
