Timeseed v2

It's a standalone Argon2 memory-hard key derivation
and AES-GCM encryption tool with
a cleaner and more intuitive interface.

Lockit — Phone companion tool

Just the Encrypt/Decrypt text tool
Using TimeSeed v2-derived keys.
Fully client-side, memory-hard, quantum resistant, no servers. Ideal for modern phones.

Open Lockit → Only compatible with TimeSeed v2

Timeseed v1 ? v1 and v2 are not cross-compatible
(except for the shared 50-character TimeSeed and Lockit key format)

The original implementation (April 2025) for compatibility with existing seeds.
Uses PBKDF2 and AES-GCM. More than secure enough, still works great and compatible with most devices.
