advice about making user details secure
hi, i am trying to make a webpage where users can submit their bank account details so that i can process payments to them offline.
It is important to make this page secure and i was wondering the best way of doing it? Should i simply hold the details in a mysql database/use an ssl certificate/encrypt the details using md5 etc?
Just to clarify, the page will simply allow the user to send their bank details to me. All payments will be made offline.
All this is new to me to any advice is much appreciated.
