hexadecimal question

[eluser]Nevio[/eluser]
I'm trying to create headache for everyone that opens database. I'm not permitting to do any changes over for example phpmyadmin or any other database manager and what I found out, no matter what charset is database, it will always render correctly because of not importing any other special characters and it's simple converting

$this->security->strToHex( 'some string for example with čćžčšžčš' );
$this->security->hexToStr( above in hex );

I guess I'm playin with database and hexadecimal lol Thanks for response jedd
