How sealing works

  1. Upload your files (up to 100 MB total)
  2. We encrypt it and request an RFC 3161 timestamp
  3. Download your .soulprop reveal key — the only copy

Keep your reveal key safe. Without it, your files stay sealed forever. When you need proof, return with your key to reveal and download your evidence package.
