Hi,
I'm developing a program (C#) that has 4 levels of authentication. To switch from one level to another you need to use a password. I want to save those passwords into a file. I read all about hashing the passwords and using long random salt for each password. The only problem is that everyone has access to this file, and therefore everyone can change its content, i.e change the salt and the hashed password to whatever password he'd like...
How do I save the salt and the hashed password in such a way that no one will be able to modify it ? (how for example other softwares do it? for example Microsoft Excel?)
All The Best,
dany
