Attest File

Create a cryptographic provenance attestation — sign any file with your Ed25519 identity to prove when and by whom it was captured or created. Supports photos, documents, sensor data, audio, video, and more.

{% if not has_identity %}
No identity configured. Generate one from the Keys page or run fieldwitness init.
{% endif %}
Accepts images (PNG, JPEG, WebP, TIFF), documents (PDF, DOCX, CSV, TXT), audio (MP3, WAV, FLAC), video (MP4, MOV, MKV), and sensor data files. Perceptual matching (pHash, dHash) is available for image files only.
