Struct Documentation

struct Profile

A single research-group profile stored in the profiles manifest.

Passwords are never stored in plain text. Only the PBKDF2-SHA256 hash and the random salt used to compute it are persisted.

Profiles are loaded from and saved to ~/.config/CSRU/mosaic/profiles.json by ProfileManager.

Public Functions

inline bool is_guest() const noexcept

Returns:

true if this is the built-in unauthenticated guest session.

inline bool has_password() const noexcept

Returns:

true if this profile has administrator privileges.

Public Members

QString username

Unique login key — lowercase alphanumeric + underscore, 3–32 chars.

QString displayName

Human-readable group name shown in the login dialog and session metadata. Example: "Cognitive Science Lab".

QString initials

One or two uppercase letters derived from displayName, shown inside the avatar circle. Example: "CL" for Cognitive Lab.

QString accentColour

Hex RGB colour for the avatar background. Assigned round-robin from a fixed palette on registration. Example: "#5566dd".

QString salt

Hex-encoded random 32-byte salt used in the password hash. Empty string means no password was set.

QString passwordHash

Hex-encoded PBKDF2-HMAC-SHA256 output (100 000 iterations, 32-byte key). Empty string means no password was set — any login attempt succeeds.

QDateTime lastLogin

UTC timestamp of the most recent successful login.

QDateTime created

UTC timestamp when this profile was first created.

Role role = Role::User

Privilege level — only Admin profiles open the admin panel after login.

QString institution

Optional lab / university / department name (shown in admin panel and status bar).
