*This project is no longer actively maintained. If you'd like to become the maintainer, please let us know.* ZeroDB is an end-to-end encrypted database. Data can be stored and queried on untrusted database servers without ever exposing the encryption key. Clients can execute remote queries against the encrypted data without downloading all of it or suffering an excessive performance hit.

## What it is
ZeroDB is an end-to-end encrypted database built on ZODB, allowing data to be stored and queried on untrusted servers without exposing encryption keys. Clients can run remote queries against encrypted data without downloading everything or suffering excessive performance loss.

## Use cases
- store encrypted data on an untrusted server
- query a database without the server seeing plaintext
- keep encryption keys client-side while outsourcing storage
- search encrypted records remotely
- build privacy-preserving cloud storage apps

## When to choose
- you need client-side encryption with queryable encrypted data on untrusted infrastructure
- you want a Python/ZODB-based encrypted database
- you're researching searchable encryption techniques

## When to avoid
- you need actively maintained software with security updates
- you need production-grade encrypted database support
- you need a database other than Python/ZODB ecosystems

## Facets
- artifact type: library
- maturity: abandoned
- function: database, cryptography, search-engine
- domain: databases, security, privacy
- platform: python
- tags: end-to-end-encryption, encrypted-database, untrusted-server, client-side-encryption, zodb, linux, macos
