Azul

Azul (short for azulejos, the colorful Portuguese and Spanish ceramic tiles) contains an implementation of a tiled certificate transparency log compatible with the Static CT API, built for deployment on Cloudflare Workers. It also contains several crates implementing various C2SP specifications. Read the blog post for more details.

The crates in the repository are organized as follows:

• ct_worker: A Static CT API log implementation for deployment on Cloudflare Workers.
• mirror_worker: A configurable tlog-mirror, tlog-witness, or combined worker. Logs are keyed by exact checkpoint origin with Ed25519 or ML-DSA-44 checkpoint signers.
• static_ct_api (crates.io): An implementation of the C2SP static-ct-api specification.
• signed_note (crates.io): An implementation of the C2SP signed-note specification.
• tlog_tiles (crates.io): An implementation of the C2SP tlog-tiles and C2SP checkpoint specifications.
