I decide to encrypt user's sensitive data (tel, address,...) using CI encryption library. In form validation rules, for some fields like mobile number, I used is_unique[table.field]. But for encrypted data, it is useless!
Is there anyway to solve this or I must write a callback function in form validation rules (a function that get a field, encrypted it and then compare it to all records)?
I want to know also your opinion for encrypting these data.

thanks.

Hi! Im new to CodeIgniter. How can you display encrypted data from the database to a, for example, a html table? Is there a function to decrypt an encrypted data? Im not sure but I think your idea to encrypt sensitive information is a good idea.

First, you need to set up an encryption key in config/config.php, for example:
PHP Code:
$config['encryption_key'] = hex2bin('6a9f0dasfdklf890qwqwea0c7f2e7c67'); 

After initializing the encryption library in your controller (or autoload it):

PHP Code:
$this->load->library('encryption'); 


You could encrypt data with:

PHP Code:
$this->encryption->encrypt($var); 

And decrypt it with:

PHP Code:
$this->encryption->decrypt($var); 

More details on CI documentation.
