What it does
DocuSign sees your documents. We don't. Post-quantum, end-to-end encrypted document signing. Your files are encrypted before they touch our servers — we can't read them even if we wanted to. Built-in identity verification via Enclave Verify, cryptographic audit trail, and one account across the entire Enclave platform. Free to start. No credit card required.
Privacy-first document signing with post-quantum cryptography. Documents encrypted client-side, ML-DSA signatures, and a verifiable audit trail. Integrated with Enclave Verify.
Enclave Sign is a post-quantum, end-to-end encrypted signing platform. Documents are encrypted on your device before they leave it - Enclave never sees plaintext. Enclave never sees plaintext documents. All content is encrypted client-side before it ever leaves the user's device. Signatures use ML-DSA (Dilithium) - making signed documents resistant to quantum computing attacks. Every signing event produces a verifiable chain of signatures and timestamps - not just a server log. A sender uploads a document, places signature fields, and sends an envelope to one or more signers. The document stays encrypted end-to-end. Signers authenticate via link and sign - all cryptographic operations…from sign.enclave.talk

Currently even the person checking if a document/contract is sealed or code is authentic has to also be inside the same Adobe walled garden too. Verification, the part that should be free is the part everyone charges for. Thats the shape Let's Encrypt fixed for TLS, and I wanted the same thing for documents and files. The core idea therefore needed to go a bit beyond e signatures and i…

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
