# Showcase: how the register of people works (pki.sgit.ai) > The first showcase slide for the section on the editor's work: pki.sgit.ai's 'how the register of people works', cropped in three stages, with its link and a QR. No key on the screenshot. *Source: · site v0.1.209 · generated from the same content as the page, so the two cannot drift.* --- Showcase · the editor's work · by studio@the-ultimate-insider # How the register of people works (pki.sgit.ai) A register of people and their public keys, verified both ways. A passkey opens a vault that keeps your keys; you publish the public half, signed; a link between two people counts only when both of them wrote it, which is the answer to the 2019 keyserver flood. [Open it on its own](../../studio-ports/lab/pki/index.md) · [the end state](../../studio-ports/lab/pki/index.html?review) · 15 seconds, three stops: the page, from a passkey to a message, two ways or not at all. ## Where it came from [pki.sgit.ai/people/how.html](https://pki.sgit.ai/people/how.html) (site v0.2.30), taken at 1440 wide on 29 October 2026 and cut in the image itself to its top 1,420 pixels: the introduction, "From a passkey to a message" and "Two ways, or not at all". The callouts use the page's own words, shortened. ## What is not on it No key, fingerprint, key QR, read key or anything private: this page is prose and a numbered list, and the parts of pki.sgit.ai that show keys (the register, a person's record) are not used. The QR on the slide is of the public link only. Built on dev's showcase template (`talk/engine/showcase.js`). --- *[Site index for agents](../../llms.txt) · [HTML version](https://the-ultimate-insider.presentation.sgit.ai/studio-ports/pki/index.html)*
