Encrypting using user's password

Question

I want to encrypt a given data using the log-in user's password on a windows machine using WINAPI. I've been looking for a function that uses a token (or something like that) but I couldn't find one.

Does anyone know how to do that?

Thanks! :-)

The Windows Data Protection API sounds like what you need. The CryptProtectData and CryptUnprotectData functions perform encryption using the logon credentials of the current user.
