⚠️ iOS not supported

TimeSeed & LockIt require desktop-class
browser capabilities for cryptographic
operations (Argon2, AES-GCM).

iPhone and iPad browsers unfortunately
are not supported
due to platform limitations.

Please use a desktop browser on macOS, Linux, or Windows.

This tool runs fully client-side. No data is transmitted or stored.

🌱 Welcome to TimeSeed

Your personal encryption toolkit — let's get you started!

1

Generate Your TimeSeed

A TimeSeed is your main identifier — a 50-character random code that generates all your encryption keys. But it can also be shared with correspondents much like a public key, if you use a pepper password.

  • Click the green "Generate" button to create a new TimeSeed
  • Or enter an existing 50-character seed if you already have one
  • Use the 📘 book icon to save/load seeds for later
💡 Pro tip: Write down your TimeSeed and store it safely offline.
2

Add a Pepper (Optional)

A Pepper is an extra secret that makes your keys even stronger.

  • Think of it as a second password layer
  • Could be a memorable phrase, PIN, or secret word
  • Same TimeSeed + different Pepper = completely different keys
⚠️ Remember: If you use a pepper, you'll need BOTH the TimeSeed AND the pepper to decrypt. Forgetting either means lost data!
3

Set a refrence Date

TimeSeed generates time-based keys — different keys for different dates. It re-keys every day / 6 months

  • Click "Use Today" to auto-fill the current date & time
  • Or pick any date manually for past/future keys (this gives lots of extra possibilities)
  • Time is optional (UTC) for extra granularity
💡 Why dates? This lets you create unique keys for each day — great for daily journals, rotating secrets, or scheduled decryption.
4

Generate LockIt Keys

Click "Generate Lockit Keys" to derive your encryption keys.

You'll get two keys:

  • 🔑 Daily Key — Unique to the exact date you selected
  • 🗓️ Long-term Key — Same for a 6-month period (semester)
💡 Which to use? Daily keys are great for journals or time-sensitive data. Long-term keys work better for files you'll access over months.
5

Encrypt with LockIt

Now use your key to encrypt or decrypt!

  • Click "Use in LockIt →" to load a key into the crypto tab
  • Switch to LockIt Crypto tab in the header
  • Enter text or choose a file to encrypt/decrypt
  • Click Encrypt or Decrypt
💡 Good to know: TimeSeed automatically uses the strongest available encryption (Post-Quantum ML-KEM when supported).
