Crypta v1

What’s New

• Desktop‑friendly installers and images:
  • Linux: native DEB/RPM packages under /opt/cryptad/Crypta with icons and menu entry.
  • macOS: DMG app image; drag‑and‑drop install.
  • Windows: per‑architecture app image with native wrapper binaries and launchers.
• Crypta Launcher (GUI): one‑click Start/Stop, live logs, and an “Open in Browser” button that appears when the node’s web UI is ready.
• Package‑based Core Updater: downloads an OS/CPU‑specific installer, shows progress and clear results, and guides you to complete the update.
• Smoother first‑time setup: follows your OS light/dark theme; higher default bandwidth; smarter datastore size suggestions based on free disk space.
• Many reliability, performance, and security improvements, including upstream fixes from Hyphanet.

Installers & Distribution

• Linux
  • Installs a desktop entry and icon on desktop systems.
  • On servers, installs a cryptad systemd service but does not auto‑start; enable/start it when you are ready.
  • Paths and menus are normalized so GNOME/KDE show the correct name and icon.
• macOS
  • DMG app image included. Unsigned builds include Gatekeeper guidance if needed.
• Windows
  • Includes native wrapper executables for x86‑64 and ARM64; the launcher chooses the right one.
• Portable archives (zip/tar.gz) remain available for manual setups.

Core Updater (New)

• Replaces self‑updating the main JAR with a package‑based flow.
• Picks the right installer for your OS/arch, downloads it to the node’s update folder, and shows clear progress in the browser UI.
• After a successful download:
  • Desktop: open the installer directly from the UI.
  • Server/headless: follow the short command shown to install with admin privileges.
• Plugin updates are unchanged and continue to work in‑app.

Crypta Launcher (New GUI)

• Start/Stop the node and stream combined stdout+stderr.
• Auto‑detects the node’s web UI (FProxy) port from logs and enables “Open in Browser”.
• Keyboard shortcuts: s start/stop, q quit; arrows/PageUp/PageDown navigate; Enter/Space activate.
• Robust process handling and log tailing; works across Linux, macOS, and Windows.

First‑Time Setup & Everyday UX

• Theme follows your OS preference (light/dark). On Linux and Flatpak, changes are detected through the desktop portal for accuracy.
• Bandwidth defaults in the First‑Time Wizard:
  • Download = 10 MiB/s; Upload = 1 MiB/s (you can change these anytime).
  • The “detected bandwidth” row is hidden until a reliable detector is available.
• Datastore sizing suggestions are smarter and safer:
  • If free space > 50 GiB: suggests 20% (minimum 10 GiB), capped at 256 GiB.
  • If free space > 5 GiB: suggests 20% (minimum 2 GiB).
• Quality‑of‑life tweaks: bookmarks open in a new tab; sharper SVG favicon (ICO fallback).

Platform‑Specific Notes

• Windows
  • Native wrapper support, graceful shutdown via an “anchor” file (with automatic fallback), and better icon/theme integration.
  • The launcher can find a bundled Java runtime inside app images.
• Linux
  • Desktop entries and icons are registered correctly; GNOME Dock shows the right app identity.
  • Server/Desktop detection avoids misclassifying headless servers. Installer creates a cryptad system user/group.
• macOS
  • DMG builds included; improved Launcher behavior for Dock and window focus.
• Snap/Flatpak
  • Snap‑aware working directories and XDG paths; Flatpak builds honor desktop‑portal theme settings. GUI hand‑offs behave correctly from sandboxed environments.

Performance, Stability & Security

• Pulls in upstream fixes from Hyphanet (e.g., safer image filtering in the PNG filter, improved hashing utilities, and randomness performance improvements).
• Reduces race conditions in fetchers and improves resource handling and logging.
• Startup hardening: clearer diagnostics, robust wrapper detection, and free‑space checks on the actual data drive.

Remote Debugging (Advanced)

• Set CRYPTAD_REMOTE_DEBUG=1 to enable JDWP on the wrapped JVM. Tunables:
  • CRYPTAD_DEBUG_PORT (default 5005)
  • CRYPTAD_DEBUG_HOST (default 127.0.0.1)
  • CRYPTAD_DEBUG_SUSPEND (y|n, default n)
  • CRYPTAD_DEBUG_TIMEOUT (ms)

Compatibility

• Java 21 is required when running outside the bundled app images.
• On Linux servers, the installer enables but does not auto‑start the systemd service: sudo systemctl start cryptad.
• Network compatibility with Fred‑era peers is preserved where applicable.

Upgrade Guide

• Using the Core Updater (recommended)
  • Open the node’s web UI, go to the update page, download the suggested package, then install it (GUI on desktop; one‑liner on servers).
• Manual download from the release page
  • Linux: sudo dpkg -i Crypta-<version>.deb or sudo rpm -Uvh Crypta-<version>.rpm
  • macOS: open the DMG and drag the app to Applications
  • Windows: use the provided app image; launch via the GUI or bin\cryptad.bat
• Portable archive users
  • Stop the node, replace cryptad.jar (or unpack the new dist), and start via bin/cryptad or the GUI Launcher.

Known Limitations

• Core updates download platform installers; final OS installation still needs your confirmation (or a short admin command on servers).
• The bandwidth “detector” is intentionally disabled in the First‑Time Wizard until it’s reliable.
