parsec-cloud: Secure cloud framework
Parsec
Parsec allows you to easily share your work and data in the cloud in total privacy thanks to end-to-end cryptographic security.
Key features:
- Works as a virtual drive on you computer. You can access and modify all the data stored in Parsec with your regular software just like you would on your local hard-drive.
- Never lose any data. Encrypted data are synchronized with the remote server that never destroys anything, hence you can browse data history and recover from any point in time.
- Client-side cryptographic security. Data and metadata are only visible by you and the ones you choose to share with.
- Cryptographic signature. Each modification is signed by its author making its identification trivial.
- Simplified enrollment. New user enrollment is as simple as sharing a link and a token code.
- Easy to self-host.
Architecture
Parsec is divided between a client (responsible for exposing data to the user and providing an encryption layer) and a server (storing the encrypted data and notifying clients about other users activity such as data modification or new sharing).
The Parsec server only requires a PostgreSQL DB for metadata (that is encrypted using devices keys for the most part) and an Amazon S3 or OpenStack Swift object storage for data blobs (that are encrypted using Workspaces keys which never leave users’ devices). Redundancy using multiple cloud providers is possible.
