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 libsodium 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 sends header separated from data)
Data (encrypted) are local only in Windows, not shared with Microsoft through roaming
UX improved (invitation redirect, offline, non-blocking modals)
