How to use

Main file is \DF\Encryption\Crypter

1. Generate a key : the key needs to be saved, or you can't decrypt further.

    $key = Crypter::generateKey()

1. Encrypt

    $key = **KEY_GENERATED**
    $text = **TEXT_TO_ENCRYPT**
    $crypter = new Crypter($key);
    $encryptedText = $crypter->encrypt($text);

1. Decrypt

    $key = **KEY_GENERATED**
    $textEncrypted = **TEXT_TO_DECRYPT**
    $crypter = new Crypter($key);
    $encryptedText = $crypter->decrypt($textEncrypted);

• Additional : check if a string is encrypted or not

    $key = **KEY_GENERATED**
    $text = **TEXT_TO_DECRYPT**
    $crypter = new Crypter($key);
    
    $crypter->isEncrypted($text);
    $crypter->isNotEncrypted($text);
