What is the best way to keep database data encrypted with user passwords?
- by Dan Sosedoff
Let's say an application has really specific data which belongs to a user, and nobody is supposed to see it except the owner. I use MySQL database with DataMapper ORM mapper. The application is written in Ruby on Sinatra.
Application behavior:
User signs up for an account. Creates username and password.
Logs into his dashboard.
Some fields in specific tables must be protected.
Basically, I'm looking for auto-encryption for a model properties. Something like this:
class Transaction
include DataMapper::Resource
property :id, Serial
property :value, String, :length => 1024, :encrypted => true
... etc ...
belongs_to :user
end
I assume that encryption/decryption on the fly will cause performance problems, but that's ok. At least if that works - I'm fine.
Any ideas how to do this?
