In plain words

This is a graphical interface for Shamir's Secret Sharing that operates entirely offline. It allows users to split secrets into shares and reconstruct them without requiring internet connectivity. The tool is designed for anyone needing to secure sensitive information through threshold cryptography, where a minimum number of shares must be combined to reveal the original secret. The offline-only approach ensures data never leaves the user's device.

  • If you lose your memory, how to regain access to your computer?Feb 2026 · eljojo.github.io · ▲402

    Due to bike-induced concussions, I've been worried for a while about losing my memory and not being able to log back in. I combined shamir secret sharing (hashicorp vault's implementation) with age-encryption, and packaged it using WASM for a neat in-browser offline UX. The idea is that if something happens to me, my friends and family would help me get back access to the data that matters most to me. 5 out of 7 friends need to agree for the vault to unlock. Try out the demo in the website, it runs entirely in your browser!

    Malai – securely share local TCP services (database/SSH) with others2025 · malai.sh · ▲117

    malai is a peer to peer network, and is a dead simple to share your local development HTTP server, without setting up tunnels, dealing with firewalls, or relying on cloud services. In malai 0.2.5, we have added TCP support, which means you can expose any TCP service to others using malai, without opening the TCP service related port to Internet. With malai installed on both ends, any TCP service can be securely tunneled over it. It can be used to secure your SSH service, or securely share your database server.
