…(DSPX-3229) Populate the Manifest Inspector from the encrypt-side manifest so the chosen KAO wrap algorithm is observable without decrypting first, and add a rewrap key algorithm selector so the client's ephemeral keypair for the rewrap exchange can be post-quantum too. Also add a .gitignore for the roundtrip harness: the root one anchors /platform and /*.pem to the repo root, so local backend bring-up artifacts would otherwise be snapshotted into the working copy. Signed-off-by: Dave Mihalcik <dmihalcik@virtru.com>
The page read as one wide row of unrelated fieldsets, and the Manifest Inspector was a six-column table that wrapped into itself below about a laptop width. Neither survives being recorded for a tablet or phone. Lay the page out as vertical flow with horizontal detail: source + sink -> encrypt | decrypt -> output + manifest Each action now carries the algorithm that affects it, so the wrap key selector sits with Encrypt and the rewrap key selector with Decrypt rather than in a shared config block. Encrypt and decrypt pair up on one row when there is room and stack when there isn't. Replace the inspector table with label/value rows per key access object, and give the session token pre its own scroll box: unconstrained it set the page's minimum width and forced the whole layout to scroll sideways.

…s (DSPX-3229) Encrypt appends the wrap algorithm to the container name, e.g. README.md-mlkem768.tdf. Decrypt carries that qualifier through and appends the mechanism used for the rewrap exchange, so a folder of demo output says which encapsulation produced which file on both post-quantum legs.

📝 WalkthroughWalkthroughThe web app now supports selectable encapsulation and rewrap algorithms. It records algorithms in encrypted and decrypted filenames, extracts KAO metadata from manifests, updates the responsive workflow UI, and expands filename and Playwright roundtrip coverage. ChangesAlgorithm-aware roundtrip flow
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to Algorithm-mismatch downloads can produce incorrect decrypted filenames because a raw key identifier is not compatible with the filename parser, potentially losing the original extension. Merge should wait for a compatible naming/parsing fix or explicit owner acceptance. Sequence Diagram(s)sequenceDiagram

I'd rather not clutter it. This is to ignore all the junk that the CI jobs create, which includes checking out a copy of o/platform here and running its scripts.

Keep mismatch output names compatible with the filename parser.
At Line 466, a KAO type mismatch replaces the supported algorithm slug with kao.kid. The parser only accepts algorithm slugs. Since EC and RSA KIDs can be values such as e1, README.md-e1.tdf parses with md-e1 as its extension. A later decrypt then produces README-rwk-p=...decrypted.md-e1.

What
Makes the ML-KEM key-wrap work from DSPX-3229 legible in the browser sample app, so it can be
demonstrated (and recorded) end to end. No
lib/changes — this is allweb-app/.Three commits:
feat(main): surface wrap and rewrap algorithm choice. The Manifest Inspector onlypopulated on decrypt, so choosing ML-KEM and hitting Encrypt left nothing on screen to show it
worked.
createZTDFreturns aDecoratedStreamwhosemanifestpromise is already resolved,so the encrypt-side inspector is free — no re-parse of the output. Also adds a rewrap key
algorithm selector:
ReadOptions.wrappingKeyAlgorithmpicks the client's ephemeral keypairfor the rewrap exchange, and left unset it falls through to RSA-2048. Without a control, half
the quantum-safe story — the DEK's journey back from the KAS — stays classical and invisible.
Also adds
.github/workflows/roundtrip/.gitignore. The root one anchors/platformand/*.pemto the repo root, so local backend bring-up artifacts (the platform symlink, generatedKAS private keys, the Keycloak CLI zip) would otherwise be snapshotted into the working copy.
style(main): restructure the layout for narrow displays. The page read as one wide row ofunrelated fieldsets, and the inspector was a six-column table that wrapped into itself below
about a laptop width. Now: vertical is flow, horizontal is detail.
Each action carries the algorithm that affects it, so the wrap selector sits with Encrypt and
the rewrap selector with Decrypt. Encrypt and decrypt pair up on one row when there's room and
stack when there isn't. Inspector table becomes label/value rows per KAO.
feat(main): tag download names with the wrap and rewrap mechanisms.ec:secp256r1)README.md.tdfREADME.md-ecsecp256r1.tdfmlkem:768)README.md.tdfREADME.md-mlkem768.tdfmlkem:1024)README.decrypted.mdREADME-mlkem768-rwk-p=mlkem1024.decrypted.mdA folder of demo output now says which encapsulation produced which file, on both legs.
Why
mlkem:768/mlkem:1024are available today but not yet the default. The demo needs to make twothings concrete that were previously invisible: that the KAO wrap really is post-quantum (visible
type: mlkem-wrapped,kid, and the 1158 / 1638-bytewrappedKey), and that the rewrap leg is aseparate choice most people miss.
How to test
Bring up the roundtrip harness backend (see
.github/workflows/roundtrip/), then:18 passed locally (3 browsers x 6 tests).
--workers=1sidesteps a pre-existing race inRemote Source Streaming:static-server.jsbinds port 8086 with no EADDRINUSE handling and allthree browser projects share
tests/README.md.tdf. Confirmed pre-existing by stashing thesechanges and reproducing 3/3 failures on the parent commit.
Test changes:
#kao-kid-0/#kao-type-0/#kao-wrapped-bytes-0immediatelyafter Encrypt (before any decrypt), and drives
#rewrapAlgorithmso the PQ rewrap leg iscovered.
download names record both key wrap legsre-uploads the file under the name encryptsuggested. The other tests hand back Playwright's temp UUID, so the filename parser's happy
path was never actually exercised — only its fallback branch.
Also
npm run lint,npm test(Vitest), andtsc --noEmitclean inweb-app.Risk
Low, and confined to the sample app. No
lib/orcli/changes, no change to the TDF container,policy model, or KAS protocol shape. The one behavioural change users will notice is the download
filenames.
Note the decrypt name keeps the existing
.decryptedinfix rather than dropping it, since it'swhat distinguishes output from input in the same folder.
