Certificate Transparency explorer

crt-explorer

Certificate transparency reconnaissance with an independent current-certificate lookup, retained crt.sh history, direct local SQLite search, and CT log ingestion experiments.

Cert SpotterCurrent unexpired issuances with bounded pagination and server-side retention.

Shodan CTFast supplemental fallback when the complete current-certificate lane is throttled.

crt.sh JSONCached endpoint reads with stale fallback when the public service gets flaky.

SQLiteImported cache rows and local suffix search for repeat lookups.

CT LogsDirect log range ingestion for experiments that bypass the crt.sh UI path.

Metadata

Public-safe project shape.

Current lookup Cert Spotter for current unexpired issuances, with crt.sh and SQLite retained-history fallbacks.

Cache 24 hour TTL by default, with stale-cache fallback for crt.sh outages.

Local DB data/crt-explorer.sqlite in the private workspace; not exposed through this public route.

Scope A reconnaissance helper, not a full CT mirror. Current results are labeled separately from the finite retained historical cache.
