Install a Database
Install curated, client-side-encrypted chemical spaces — online or fully air-gapped — or bring your own.
Navigator screens a make-on-demand chemical space (reactions + synthons). You
can bring your own via ./inputs, or install one of Deep-MedChem's curated
spaces (e.g. Freedom Space, ~1.8M synthons).
How releases are secured
Database releases are client-side encrypted: the bundles are served from a
public bucket as ciphertext, so the download needs no credentials, and only your
machine can decrypt them. The database install key is embedded in your signed
license (the same license.json from Activate your
license), so there is normally nothing extra to
install — activating your license also enables database decryption.
Air-gapped / override
If Deep-MedChem instead sends a standalone key, save it as ./db_install.key
(or point DMC_NAV_DB_INSTALL_KEY_FILE in .env at it); a non-empty key file
takes precedence over the license-embedded key.
Browse and install
navigator data catalog # databases you can install
navigator data install freedom-space-5 # download + verify + decrypt + install
navigator data list # -> ["freedom-space-5@2026-03-296b.2"]
navigator data verify freedom-space-5@2026-03-296b.2 # re-check signature + hashesdata install downloads the encrypted objects, verifies the release's Ed25519
signature before touching any payload, unwraps the data key locally with your
install key, decrypts, checks every hash, and atomically installs into
./databases. Nothing is decryptable without the install key, and a tampered
bundle fails closed.
Fully offline / air-gapped install
If the host has no internet, copy the release bundle onto it (same catalog/ +
releases/… layout) and point the installer at the local mirror — decryption
still happens on-box with your key:
navigator data install freedom-space-5 --source /mnt/usb/dmc-navigator-databasesRemove a release you no longer need with navigator data remove <db@release>.
