The Photon operating system must store only encrypted representations of passwords.
Overview

| Description |
|---|
| Passwords must be protected at all times via strong, one-way encryption. If passwords are not encrypted, they can be plainly read (i.e., clear text) and easily compromised. If they are encrypted with a weak cipher, those passwords are much more vulnerable to offline brute-force attacks. |
