# Phase 12 Plan 02: FOFA, Netlas, BinaryEdge Sources Summary

**Three IoT/device scanner recon sources (FOFA, Netlas, BinaryEdge) with httptest-based unit tests covering sweep, auth, and cancellation**

## Performance

- **Duration:** 2 min
- **Started:** 2026-04-06T09:22:18Z
- **Completed:** 2026-04-06T09:24:22Z
- **Tasks:** 2
- **Files modified:** 6

## Accomplishments
- FOFASource searches FOFA API with base64-encoded queries and email+key authentication
- NetlasSource searches Netlas API with X-API-Key header authentication
- BinaryEdgeSource searches BinaryEdge API with X-Key header authentication
- All three sources follow established Phase 10 pattern with shared Client, LimiterRegistry, BuildQueries

## Task Commits

Each task was committed atomically:

1. **Task 1: Implement FOFASource, NetlasSource, BinaryEdgeSource** - `270bbbf` (feat)
2. **Task 2: Unit tests for FOFA, Netlas, BinaryEdge sources** - `d6c35f4` (test)

## Files Created/Modified
- `pkg/recon/sources/fofa.go` - FOFASource with base64 query encoding and dual-credential auth
- `pkg/recon/sources/fofa_test.go` - httptest tests for FOFA sweep, credentials, cancellation
- `pkg/recon/sources/netlas.go` - NetlasSource with X-API-Key header auth
- `pkg/recon/sources/netlas_test.go` - httptest tests for Netlas sweep, credentials, cancellation
- `pkg/recon/sources/binaryedge.go` - BinaryEdgeSource with X-Key header auth
- `pkg/recon/sources/binaryedge_test.go` - httptest tests for BinaryEdge sweep, credentials, cancellation

## Decisions Made
- FOFA uses base64-encoded qbase64 query parameter (matching FOFA API spec) with email+key in query string
- Netlas uses X-API-Key header; BinaryEdge uses X-Key header (matching their respective API specs)
- All three use bare keyword queries via default formatQuery path (no source-specific query formatting needed)

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
None

## Known Stubs
None

## User Setup Required
None - no external service configuration required.

## Next Phase Readiness
- Three IoT scanner sources ready for RegisterAll wiring
- FOFA requires email + API key; Netlas and BinaryEdge require API key only
