i am writing an application that will need to store less than about 1mb

  • 0

i am writing an application that will need to store less than about 1mb of data. this data will be read and edited by the user. this data will be very simple ascii data. the application is in vb.net on a windows-form. the data will be stored locally on the person’s computer. i have several questions.

  1. what kind of encryption method should i use to store the data? the user wants something that is not too powerful, but not too simple either.

  2. how should i store the data? why not just write it to some file and encrypt it using some medium encryption method?

  3. is application settings data encrypted? perhaps i can store it that way? is it suitable to store about 1mb in application setting data? how would i do this? which variable would i use?

    You can just use any stream based writing technology, and wrap the stream in a CryptoStream. This works great for saving to a file of any form, but will work with any storage medium that is stream based.

    Also – application settings are not encrypted (by default).
