Parsec is a free software (AGPL v3) aiming at easily share your work and data in the cloud in a total privacy thanks to end-to-end cryptographic security.
Works as a virtual drive on you computer. You can access and modify all the data stored in Parsec with your regular softwares 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 it author making trivial to identify modifications.
Simplified enrollment. New user enrollment is simple as sharing a link and a token code.
Simple to host. Parsec server only requires a PostgreSQL DB and Amazon S3 or OpenStack Swift object storage.
Parsec is divided between a client (responsible for expose data to the user and provide an encryption layer) and a server (storing the encrypted data and notifying clients about other users activity such as data modification or new sharing).
