Decrypting: authentication error when using the encryption library

Hello friends,

I am currently trying to use the encryption library on Codeigniter 4 (I am not using it for passwords   ). When i use the $this->encrypter->encrypt($var) , it seems to work, cus I don't get any errors and I get what seems like gibberish in my database as I would want to. 

However , when I fetch the encrypted data and try to decrypt I get this error :  "Decrypting: authentication error" . Below are my codes.

Encryption config file

Code:

public $key = 'secret key';

Constructor to initialize service

Code:

public function __construct()
  {
$this->encrypter = \Config\Services::encrypter();

}

Decrypting: authentication failedDecrypting: authentication failed
Encrypting data

Code:

$this->encrypter->encrypt($var)

Decrypting: authentication failed
Decrypt data

I tried both

Code:

<?=$encrypter->decrypt($var);?>

and

Code:

<?=$encrypter($var,$key);?>

Yet I was still getting errors, Any help is appreciated.

Regards.

You should use base64_encode() and base64_decode() methods.

PHP Code:

$this->encrypter->encrypt(base64_encode($var));

$encrypter->decrypt(base64_decode($var)); 


What did you Try? What did you Get? What did you Expect?

$this->encrypter->encrypt(base64_encode($var));

$encrypter->decrypt(base64_decode($var)); 


Hello InsiteFx ,

I have tried this method and i'm still getting the same Decrypting: authentication failed. error.

Hello Everyone I was able to solve the problem, I was loading the encryption service without loading the and passing the default configuration first, so instead of :

Code:

public function __construct(){

  $this->encrypter = \Config\Services::encrypter();

}

I did this :

Code:

public function __construct(){

  $this->config    = new \Config\Encryption();      // load the configuration for the encryption service
  $this->encrypter = \Config\Services::encrypter($this->config); // start the encryption service
}

Just to add , using base64_encode and base64_decode does not work for me
