Encrypter class error

I have used encrypter class:

Code:

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

$abc = 'abc/def/ghi';
$encrypt = $this->encrypter->encrypt($abc);
$decrypt = $this->encrypter->decrypt($encrypt);

There is an error "authentication failed".

Hi , I had a similar problem , you have to load the default encryption configuration in the config folder this way:

PHP 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
} 


And then you can use $this->encrypter to encrcypt and decrypt, also ensure that OpenSSL is enabled in php.ini , I asked and found the solution to the same problem here
