generation and stores cryptographic keys, passwords, or certificates.

Incorrect Answers:
A: Encrypting File System (EFS) is a software-based encryptions solution that is used to encrypt files or entire volumes in a Windows computer. It is not a hardware-based encryption
solution.
B: TrueCrypt is an open source software-based encryption solution.
D: SLE (Single Loss Expectancy) is a risk management concept that measures the potential dollar value loss from a single risk-realization incident. It is not related to cryptography.
