guardata 0.1.0

Desktop client for a modern and trustless data cloud storage service

guardata is a secure and trustless cloud storage service, to share and sync your files with on-premise modern encryption.

Homepage: https://guardata.app

Key features :

• Cloud storage

• Virtual drive

• Time machine

• Local encryption, Trust no one

• Share & sync securely

• Access control and logging

• open source

guardata is based on the Parsec technology developed by Scille. The code base is a fork from parsec-cloud. The cryptographic routines are provided by the lisodium library.

Differences with the Parsec reference implementation :

• The encryption stream cipher algorithm is updated from Salsa20 to Chacha20. guardata is using XChaCha20-Poly1305 which has an IETF draft standard, and is used by NordPass and by CloudFlare.

• The password key derivation algorithm is setup to be 6 times stronger

• Password strength required in the GUI is much higher

• The debug monitoring telemetry is fully removed, for a full hassle-free privacy

• Files blocks cut size is bigger, optimised for internet synchronization

• SHA2 hash is replaced everywhere by Blake2b

• More secure short codes for 2-way auth : from 40 bits with hmac-sha2 to 50 bits with argon2id

• Improve server socket management (parsec-cloud read data 5 bytes by 5 bytes, send header separated from data)

• Data (encrypted) are local only in Windows, not shared with Microsoft through roaming

• UX improved (invitation redirect, offline)
