Common questions
How does burn-on-read work?
On successful download, the relay runs GETDEL on the Redis key in a single round-trip — read and delete are atomic. A second request returns 404 regardless of credentials.
Can I recover a burned blob?
No. Once burned, the ciphertext is gone from RAM. If the TTL expires before download, the blob is also deleted.
What is the max file size?
5 MB per blob in v1. For larger payloads, chunk client-side and send N blobs (the wire format reserves FLAGS for multi-part in v1.x).
Can I use it without a post-quantum algorithm?
Anonymous sends use AES-256-GCM only (key in URL fragment). Authenticated sends use ML-KEM-768 + AES-256-GCM.
How do I rotate an API key?
Dashboard → Keys → Revoke. New key issued immediately. Old key returns 401 on the next request.
