text file security

[jdjd1118]

I have a simple program that saves a list of usernames and passwords and saves to a file. Is there a simple way I can encrypt these files? Thanks

Whetehr or not you choose to encrypt the files, which you don't really have to do, I'd suggest that you run a one-way hash algorithm on the passwords: http://msdn.microsoft.com/library/d...m/html/vxconProtectingPasswordCredentials.asp

True! John is right ... you should always check it out before decide that something is candidate for encryption

Hi

Recommendation from Microsoft on this is to use the DPAPI to store keys.

Look at the pdf file 'Building Secure ASP.Net Applications' on the MSDN Security Developer Centre. The 'How To' section near the end gives all of the code that you need.

Hope this helps
