Immutable Evidence Generation creates cryptographic proof that a file existed in a specific state at a specific time — without uploading the file itself.
Your data remains local to your browser; only a hash and minimal metadata are recorded.
The result is an evidence packet that preserves the file's original state and can be independently verified later.
This is designed for situations where integrity, provenance, and immutability matter.
Proof, not storage.
Useful when:
These tools run entirely in your browser. Files and packets never leave your machine. This proves the file you have now matches the proof you received then.
