kafka 0.1.1

Superseded

Release

Released: 18 Jul 2026
Needs: any doze
Plugin protocol: 1
Engines: Kafka protocol 1–4
Platforms: 3 of 3
Advisories: None known

0.1.1 sets no oldest doze, so it runs on every doze (0.1.0 and up).

What changed between 0.1.1 and 0.1.2

From doze-modules history

0.1.2[date]
No notes for this release.

Same plugin protocol (1) and the same engines (Kafka protocol 1–4) throughout, so the upgrade needs no change to doze.hcl.

Projects pinned to 0.1.1 keep using it until someone runs doze modules upgrade. Nothing moves on its own: not doze up, not time, not a new release.

From doze 0.2: the newest release your doze can run

$ doze modules upgrade kafka

Artifacts

One signed archive per platform. Files live on GitHub; the registry lists them and signs their checksums.

Platform	File (downloads from GitHub)	SHA-256	Signature (ed25519)
macOS arm64 aarch64-apple-darwin	kafka-plugin-0.1.1-aarch64-apple-darwin.tar.gz	`c5dfcbf911517ac8718aac8f7f9f94fceb473a4482cad37abf68ec4472c71ed6`	`GzptrkDH…l7Aw==`
Linux arm64 aarch64-unknown-linux-gnu	kafka-plugin-0.1.1-aarch64-unknown-linux-gnu.tar.gz	`644d99d060ea0878c47f4b8a6dab5ab2bbc6d73462a0fe3576aaec056c33b184`	`vHh6qEQ5…M8Dg==`
Linux x86_64 x86_64-unknown-linux-gnu	kafka-plugin-0.1.1-x86_64-unknown-linux-gnu.tar.gz	`eaf11bab449e281be6483cf18586502ffef2b4db6c5426db5fbe01ce02cc4640`	`Z7x2JMNm…R1BQ==`

Every file is under https://github.com/doze-dev/doze-modules/releases/download/kafka/. Intel Macs and Windows have no build; WSL2 uses the Linux x86_64 file.

Signing

The index is signed as a whole, and each archive is signed. doze checks both before anything runs, and refuses a module whose checksum or signature doesn't match.

Key: Nu5y8mbj…Wjw=
Where the key lives: Compiled into doze. doze never fetches or trusts a key on first use.
Namespace: doze
Publisher: doze-dev Official
Index signature: 19MD2zxM…CA==
What is signed: Each archive: its lowercase-hex SHA-256. The index: module, namespace, releases and channels as canonical JSON.
Not yet signed: The doze (oldest doze) field sits beside the signed part today. new The design moves it inside.

How signing works

Verify it yourself

[planned: doze modules verify] Today doze runs these checks itself on every download. The same checks by hand, for macOS arm64. Needs OpenSSL 3: the openssl that ships with macOS has no ed25519 (brew install openssl@3).

Checksum, then signature

# 1. download and hash; compare with the table above
$ curl -LO https://github.com/doze-dev/doze-modules/releases/download/kafka/kafka-plugin-0.1.1-aarch64-apple-darwin.tar.gz

# 2. the signature is over that hex string, with doze's public key
$ printf %s c5dfcbf911517ac8718aac8f7f9f94fceb473a4482cad37abf68ec4472c71ed6 > digest.txt

What doze.lock records for 0.1.1

A project pinned to 0.1.1 carries this entry. doze modules upgrade replaces it whole: release, engines and checksums move together in one reviewable diff. Every platform's checksum goes in, so a teammate on Linux verifies against the same pin you made on a Mac. Pinned and cached means no network at all.
