I have some files that users will store on their machines that may have sensitive information such as SSNs. We want to make sure that those files can only be decrypted on the machines they were encrypted on. I was going to use ProtectedData ProtectedData.Protect / ProtectedData.Unprotect ()

to ensure that those files encrypted on one machine can be decrypted on that machine, but do I need to also encrypt the data using something else like this to encrypt the string in question?

OpenSSL AES-256 is a great choice that is not too difficult to implement – Jake Psimos Jul 28 '16 at 14:39

ProtectedData seems to do the job you want. – Magnus Jul 28 '16 at 14:44
But if somebody has access to the computer then they could decrypt those files right? – Matthew The Terrible Jul 28 '16 at 14:44

ProtectedData seems to be able to set the scope to either CurrentUser or LocalMachine – Magnus Jul 28 '16 at 14:46

Secure the machine; don't share username/password – Black Frog Jul 28 '16 at 15:34
