Secure Issue

there is a way to post form variables in the best secure way...
i don't sure how or what is the technical way to do this and that is the aim of this subject...

banks,visa, master card...all of them working with such secure way...
you fill some form, than the submited form is being saved in a cookie and than a new window opens and read all the data from the cookie and saving it into the database...
my question is why??

how it works? can someone explain and show me how?
:confused:what is the logic to do this and not to post it from page to page?

Use SSL

ssl is a good way to secure but i asked about this specific one...

That IS the way.
SSL encrypts it for you.

Otherwise, you're stuck encrypting it yourself. And decrypting it on the other side. Nothing else is truly secure, as it's plain text. There may be encryption algorithms out there, but what's the point when all you need to do is set up SSL on the server?

For bank-level info, credit cards, and social security numbers, SSL is the ONLY way.

imagen that the form passing all the data to the cookie after encryption and the other page that opens reading decrypting the data from the cookie...
this is not ssl but is it good that way? is it better than posting ecrypted data from page to page?

what do you think better:
ASP PAGE > ASP PAGE > SQL
ASP PAGE > COOKIE , COOKIE > ASP PAGE > SQL
? ;)

No, it's not good that way. Use SSL. If you've got data that you need to encrypt, don't save it to people's hard drives, encrypted or not. Use SSL.
