Status

v0.2.0 — feature drop. Alpha; expect rough edges. The on-wire format is still locked, so blobs encrypted with any v0.x release keep decrypting on later versions.

What v0.2 adds on top of the v0.1 baseline:

  • Web Worker for crypto. RSA-4096 keygen and Argon2id-at-prod-params no longer block the main thread on signup or login. The EncryptAnim actually animates instead of stuttering.
  • IndexedDB-backed key store. The wrapped private key now lives in IDB, with one-shot migration from any pre-existing localStorage entry.
  • Streaming uploads. The upload route reads files via File.stream() instead of file.arrayBuffer(), so the SPA no longer trips ArrayBuffer size limits on multi-hundred-megabyte uploads.

Plus the v0.1.3 → v0.1.5 fixes already in: owner-visible "shared with" chips on /doc/:id, manual Cloudflare pageviews on the public auth routes only (no leak past login), and a strict-ish Content-Security- Policy on the SPA.

How it works

Vellaris encrypts files on your device with a fresh AES-256 key, then encrypts that key once for each recipient with their RSA-4096 public key. Your self-hosted server only ever holds ciphertext, encrypted-DEK rows, and a signed audit log — it cannot decrypt anything.

crypto: AES-256-GCM · RSA-4096 OAEP-SHA256 · Argon2id passphrase KDF

Three clients, one trust boundary

Client Install When to reach for it
CLI pip install vellaris Engineers, scripts, CI pipelines
Python SDK pip install vellaris Automations, ETLs, webhook handlers
Web Static SPA, deploy-anywhere Colleagues who don't live in a terminal

Every client speaks the same on-wire protocol; the server publishes its contract at /openapi.json.

Run a server

Docker

Pull the slim image (~120 MB, SQLite + local FS only):

docker pull ghcr.io/subhayu99/vellaris:0.5.0

Or the full image (~350 MB, every DB and cloud storage backend bundled):

docker pull ghcr.io/subhayu99/vellaris:0.5.0-full

For a tailored configuration (e.g. Postgres + S3 only) and a copy-paste docker run command, use the deployment configurator.
