我可以使用SSL加密PHP中提交的表单数据吗？

Question

if i bough SSL Certificate for my site, can i encrypt submitted form data manually in PHP then store it to database?

Please Explain me what ssl does?

Example:

visitor of the site enter username and password, can i encrypt both data in php by using SSL?

like this.

$u_name = verisign_ssl_encryption($_POST['username']);
$pass = verisign_ssl_encryption($_POST['password']);

mysql_query('insert into table (username,password) values ("'.$u_name.'", "'.$pass.'")';

and can i decrypt retrieved encrypted data from table by using same SSL like this

$row = mysql_fetch_array(mysql_query('select * from table where u_id = 1'));
$user_card_no = verisign_ssl_decrypt($row['card_no']);
echo $user_card_no;

or SSL is something different from like this?

Advance thanks for your answers!

Answer 1

SSL can be used in many ways, but I think the way you mean you will need ssl support for your website. With apache you can do this with modssl http://www.modssl.org/.

You should consult with your hosting provider to configure your website with ssl support.
