Encryption today mostly means trusting apps, update pipelines, and centralized infrastructure. Even “end-to-end” systems still depend on vendors, app stores, and forced updates.
Timeseed v2 is an attempt to remove that dependency entirely.
It’s a lightweight, open-source, client-side encryption tool that runs as a standalone HTML file (online or fully offline, air-gapped if you want). No accounts, no servers, no key exchange.
Instead of contacts and key servers, Timeseed uses deterministic time-based key derivation:
Generate a high-entropy TimeSeed root
Optionally add a secret pepper
Derive reproducible passkeys scoped to daily, monthly, or long-term periods
Rotate keys simply by advancing the date — no coordination required
Crypto stack:
Argon2id (memory-hard KDF)
AES-GCM (authenticated encryption)
Per-operation random salts and IVs
All encryption happens locally before any network touch
You can share a TimeSeed publicly if it’s pepper-protected, or keep everything private. Re-keying is trivial. No identifiers tied to phone numbers, emails, or IPs.
Timeseed v2 also includes LockIt, a companion encrypt/decrypt tool for text and files using derived passkeys — useful on desktop or mobile in constrained situations.
This isn’t a messaging app. It’s pre-network encryption you control.
If you believe sovereignty means owning your keys and your tooling, this may be useful.
