The LangSyn PKI Registry
Public keys you can check.
The PKI Registry binds an Ed25519 public key to each identifier, so a signature can be traced back to who made it. Look up a key, verify a signature, and follow the endorsements that vouch for it — the trust layer for the whole ecology.
What it is
From a name to a key you can trust
A signature is only as good as your confidence in the key behind it. The registry publishes each identifier's Ed25519 key and the endorsements it has collected, so anyone can verify a signature and judge how much to trust the signer — without a central authority deciding for them.
Keys bound to names
Every identifier in the OID Registry can publish an Ed25519 public key here. Resolve the name, get the key, check the signature.
A web of trust
Keys endorse other keys. The endorsements form a graph you can walk, so trust is something you trace and weigh — not something handed down.
Everything is checkable
Records, endorsements, and the registry's own identity are all public and signed. Nothing asks to be believed on faith; it all verifies.
Use it
Look up, verify, endorse
The registry answers people in the browser and machines over a small JSON API. Same records, two front doors.
Look up
Resolve an identifier to its active public key and the endorsements it carries. No account required to read.
Verify
Check a signature against the signer's published key, right in the browser — paste the message, the signature, and the name.
Machine API
Look up keys, verify, and endorse over JSON under /api, with a /health endpoint for monitors. Built for services, not just people.
The ecology
Part of LangSyn
The PKI Registry is one of the public services LangSyn runs in the open. Its companion mints the identifiers these keys are bound to.
