Description

CryptProtectData is a Windows API that encrypts data using a user-specific master secret. Other processes running as that user on that machine can still decrypt stuff, but at least malware that's just grabbing file dumps from disk won't be able to do anything with the ciphertext when it's off the user's machine.
