LLM Prompt Injection Tester  v4.0.0
Target: Burp Suite 2026.x  (Jython 2.7)
Prompts: github.com/CyberAlbSecOP/Awesome_GPT_Super_Prompting

NEW IN v4.0.0:
  - Response Diffing        : baseline vs injected, colour-coded diff panel
  - Token / Secret Extractor: auto-extract API keys, JWTs, PII from responses
  - Multipart / Form-data   : inject into multipart fields, not just JSON
  - Header Injection        : try X-System-Prompt, X-User-Message, etc.
  - SSE / Streaming         : reassemble text/event-stream before scoring
  - Rate Throttle           : 429 detection + exponential back-off + retry
  - Parallel Workers        : configurable thread pool (1-10 workers)
  - Finding Deduplication   : collapse identical URL+pattern combos
  - HTML Report Export      : client-ready HTML report one click
  - Prompt History Tab      : per-prompt match rate, top performers view
  - Burp Collaborator       : optional OOB exfil detection
  - Per-prompt stats        : hit count / test count persisted between sessions

INSTALLATION:
  1. Extender -> Options -> Python Environment -> Jython standalone JAR
  2. Extender -> Extensions -> Add -> Python -> select this file
  3. Tab "LLM Injector" appears in Burp

          rather than bytearray() to avoid sign/type errors.
        * Writing to DataOutputStream requires a real Java byte[] — obtained via
          helpers.stringToBytes() which returns the correct type.
        * All except clauses are bare 'except:' so Java exceptions are caught too.
