Communicator™ — Encrypted Chat (Port 49199)

Persistent 1-hour telnet chat server with end-to-end encryption negotiation.

Cipher Options (dropdown):

#	Cipher	Key Size	Notes
1	AES-256-GCM	256-bit	Default. Authenticated encryption.
2	RSA-2048	2048-bit	DH derives symmetric key, RSA for signing.
3	RSA-4096	4096-bit	Higher security RSA variant.
4	Twofish-256	256-bit	BouncyCastle; falls back to AES-256-CBC.
5	ECC-secp256r1	256-bit	ECDH key exchange + AES-GCM.
6	ChaCha20-Poly1305	256-bit	Modern stream cipher with authentication.

Key Exchange: DH-2048 (RFC 3526 Group 14) for ciphers 1–4,6. ECDH (secp256r1) for cipher 5.

Protocol:

telnet localhost 49199
identify <nationalId>
encrypt                          ← show cipher dropdown
encrypt 1                        ← initiate AES-256-GCM via DH
  → server sends DH public key (hex)
encrypt accept <your_pubkey_hex> ← complete key exchange
  → session now encrypted
encrypt off                      ← disable encryption

Profile (persistent settings):

profile                      ← view current settings
profile cipher 6             ← save ChaCha20 as default (auto-suggests on next login)
profile clear                ← clear preference

Module Startup/Shutdown Scripts

All modules have dedicated scripts at their root for frontend (webapp) and backend (TCP servers).

Brarner.M.Alete™

Script	Purpose
start.sh	Build WAR + deploy to Tomcat + start Tomcat
shutdown.sh	Undeploy from Tomcat (--stop-tomcat to also stop Tomcat)
start-backend.sh	Start TCP servers (Postal, SSA, Art, Legal)
shutdown-backend.sh	Stop all backend TCP servers

Location: modules/black/presidential/Brarner.M.Alete/

Green.Durham.Grass.and.Herb™

Script	Purpose
start-frontend.sh	Deploy webapp to Tomcat + start Tomcat
shutdown-frontend.sh	Undeploy from Tomcat (--stop-tomcat)
installation/start.sh	Start backend TCP server (Appree, listeners)
installation/stop.sh	Stop backend

Location: modules/black/presidential/Green.Durham.Grass.and.Herb/

Futures™ (Democratic ProFront National 1.0)

Script	Purpose
start-frontend.sh	Deploy webapp to Tomcat + start Tomcat
shutdown-frontend.sh	Undeploy from Tomcat (--stop-tomcat)
bash/start.sh	Start AI server on port 5000
bash/shutdown.sh	Stop port 5000 server

Location: modules/black/red/Futures/

Black Belt™

Script	Purpose
start.sh	Deploy webapp to Tomcat + setup MySQL + start Tomcat
shutdown.sh	Undeploy from Tomcat (--stop-tomcat)

Location: modules/black/belt/

Main NWE (all backend modules)

Script	Purpose
scripts/startup.sh	Start NWE Main (all servers, G1GC, 4GB heap)
scripts/start-backend-modules.sh	Start NWE + verify all 19 ports
scripts/start-backend-modules.sh --stop	Stop NWE Main

Integrity System

Post-install SHA-256 file verification. Non-blocking — program continues running regardless of findings.

Tech ID: Gifted Install Tech ID (not MEARVK LLC Installer Tech ID)

Schedule: Every 2 days at 06:00 (0 6 */2 * *)

Scripts:

File	Purpose
integrity/post-install-integrity-check.sh	Main integrity scan (SHA-256 + MD5)
cron/integrity-check.sh	Cron wrapper for periodic runs
integrity/integrity-schema.sql	MySQL schema for nwe_integrity database
modules/black/red/Futures/bash/integrity.sh	Futures-specific integrity check
modules/black/presidential/Brarner.M.Alete/install/verify-integrity.sh	BMA integrity verification
modules/black/presidential/Brarner.M.Alete/install/generate-integrity.sh	BMA digest generation

Behavior:

1. Self-integrity check first (verifies its own scripts)
2. Full SHA-256 + MD5 scan of all git-tracked files
3. On corruption (same commit, different hash) → auto-restore from GitHub
4. On update (different commit) → preserve original digests in integrity/history/
5. Concerns logged to integrity/concerns/ (non-blocking, append-only)

Database: nwe_integrity — tables: honor_oath, file_digests, file_digests_history, integrity_concerns, scan_history

No DELETE on any table. No UPDATE on history or concerns.

Trusted servers:

• github.com/mearvk/Java.Web.Server.Telnet.Front.Java.21 (primary)
• github.com/ElisabethHarkins5509 (secondary)

Install:

mysql < integrity/integrity-schema.sql
bash integrity/post-install-integrity-check.sh
sudo bash cron/install-cron.sh
