protonURL

proton URL allows you to share secret, confidential or non-confidential content via a link that will self-destruct on first reading.

Deletion proofs certify that a URL's content has been permanently destroyed — after being read or upon expiration. Since version 2, each proof is cryptographically signed with protonURL's ECDSA private key. Proofs generated before the v2 update contain a SHA-256 hash of content metadata. protonURL protects your information in transit — but once shared, an idea has no timestamp.
