Encrypt Decrypt in Codeigniter - Insert Data

[@YudiKondo]

Good tutorial! For me all personal data need to be encrypted! Tnks!

Hi Man, How did you generate the encryption KEY? Is it random generation? I'm talking about the key you wrote in $config['encrypt'] in the config file

[@limitedlifetime8443]

$this->encryption->create_key(16)

You can find it in codegnitor encryption keys ;.type that and search you will get codegnitor page.

Hello. Very nice tutorial. In creating the database, what are the length/values of the fields? How many characters will the inserted encrypted texts will be? Thanks.

[@faizzulfikar3692]

but, how to make that encryption key in config.php.?

[@YudiKondo]

echo bin2hex($this->encryption->create_key(16));
Copy and past
$config['encryption_key'] = hex2bin();

[@faizzulfikar3692]

@@YudiKondo i don't undestand how "echo bin2hex($this->encryption->create_key(16));" are works
but i tried,
$str = bin2hex("key");
echo($str);
and encoded key are shown.

Encryption Library:
The key should be as random as possible and it must not be a regular text string, nor the output of a hashing function, etc. In order to create a proper key, you must use the Encryption library’s create_key() method
// $key will be assigned a 16-byte (128-bit) random key
$key = $this->encryption->create_key(16);
The key can be either stored in your application/config/config.php, or you can design your own storage mechanism and pass the key dynamically when encrypting/decrypting.
To save your key to your application/config/config.php, open the file and set:
$config['encryption_key'] = 'YOUR KEY';
You’ll notice that the create_key() method outputs binary data, which is hard to deal with (i.e. a copy-paste may damage it), so you may use bin2hex(), hex2bin() or Base64-encoding to work with the key in a more friendly manner. For example:
// Get a hex-encoded representation of the key:
$key = bin2hex($this->encryption->create_key(16));
// Put the same value in your config with hex2bin(),
// so that it is still passed as binary to the library:
$config['encryption_key'] = hex2bin();
