Encrypt::encode() 

\nn\t3::Encrypt()->encode($data = ''); 

Encrypts a string or an array.

In contrast to \nn\t3::Encrypt()->hash(), an encrypted value can be decrypted again using \nn\t3::Encrypt()->decode() can be decrypted again. This method is therefore not suitable for storing sensitive data such as passwords in a database. Nevertheless, the level of protection is relatively high, as even identical data encrypted with encrypted with the same salting key look different.

A salting key is generated for the encryption and stored in the nnhelpers Extension Manager. This key is unique for each installation. If it is changed, data that has already been encrypted cannot be be decrypted again.

\nn\t3::Encrypt()->encode( 'mySecretSomething' );
\nn\t3::Encrypt()->encode( ['some'=>'secret'] );

Complete example with encryption and decryption:

$encryptedResult = \nn\t3::Encrypt()->encode( ['password'=>'mysecretsomething'] );
echo \nn\t3::Encrypt()->decode( $encryptedResult )['password'];

$encryptedResult = \nn\t3::Encrypt()->encode( 'some_secret_phrase' );
echo \nn\t3::Encrypt()->decode( $encryptedResult );
