Six protocol tools, a page for every format, tool bar (0.4.0) - #2

Conversation
New in public/protocols.js, wired into the auto-detect: - SSH public keys, authorized_keys / known_hosts lines and OpenSSH certificates, with ssh-keygen-compatible SHA256 and MD5 fingerprints; OpenSSH private keys expose only their public half - Protobuf wire format without a schema (protoc --decode_raw style) - WebAuthn / passkey payloads via an own CBOR decoder: client data, attestation, authenticator flags, AAGUID, COSE key as JWK and PEM - OAuth 2.0 / OIDC requests, callbacks, token requests and responses with security checks, a live PKCE verifier check and ID-token decoding - JWE header/envelope inspection (no decryption) and JWK / JWKS with RFC 7638 thumbprints, leak detection and PEM export - DNS wire format, DoH URLs, and SPF / DKIM / DMARC record checks Pages for formats the site already read: Base64, URL, JSON, timestamps (now s/ms/µs/ns and dates to Unix time), cURL and HTTP requests. A tool bar under the header lists all 17 tools; the bottom list is grouped. Tests: 22 protocol tests against ssh-keygen, RFC vectors, node crypto and the encoders in build/encoders.js.

Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughThe change adds protocol parsers and connects them to decoder analysis. It expands the site catalog to 17 tools, adds decoder pages, and updates navigation, examples, tests, and review settings. ChangesDecoder and tool expansion

Merge Risk: 🟡 Moderate · up to The test suite currently fails because a generated file is out of date. Two kinds of malformed input stop the decoder page from updating: a truncated OpenSSH private key, and an Ed25519 DKIM record with an invalid key. Regenerate the file and fix both input cases before merging. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

minimal, and validate.
Inline comments:
In `@public/decoder.js`:
- Line 363: Update analyzeOpensshPrivate to match the OpenSSH private-key body
with an optional END marker, so truncated keys still return a private-key result
and never fall through to generic decoders. Preserve its existing catch behavior
for unreadable bodies.
In `@public/examples.js`:
- Line 26: Update the generated examples data in public/examples.js so it
matches the current page generator output and passes the generated-file check.
In `@public/protocols.js`:
- Line 1197: Guard the Ed25519 key parsing in the `analyzeMailRecord` branch
that assigns `info.Key` using `base64ToBytes(tags.p)`. On invalid Base64, add a
failed `p` check with an explanatory message instead of allowing the exception
to escape; preserve the existing key description for valid input.
- Around line 1019-1051: Update rdataText to validate each record type’s minimum
data length before reading fixed fields, including DS, DNSKEY, and CAA. Ensure
every decoded name ends within the record’s end boundary, and verify the
complete SOA numeric fields fit before reading them; reject malformed records
instead of reading into subsequent data.
In `@public/timestamp-converter/index.html`:
- Around line 119-120: Update the “Why does my timestamp land in 1970?” answer
in the page and its JSON-LD `acceptedAnswer` so it names the digit-to-unit
mappings directly instead of referring to a list above. Keep both answers
consistent and independent of page layout.

…e gzip - OpenSSH and PEM private keys with a missing END line stop at the private-key result instead of reaching the Base64 decoder - Ed25519 DKIM keys with invalid Base64 report a failed check - rdataText validates minimum lengths and name bounds per record type - gzip example pinned to OS byte 3, so examples.js is identical on every platform (this was the CI staleness) - Timestamp FAQ names the digit-to-unit mapping directly Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
