Key Transparency
Key Transparency provides a lookup service for generic records and a public, tamper-proof audit log of all record changes. While being publicly auditable, individual records are only revealed in response to queries for specific IDs.
Key Transparency can be used as a public key discovery service to authenticate users and provides a mechanism to keep the service accountable. It can be used by account owners to reliably see what keys have been associated with their account, and it can be used by senders to see how long an account has been active and stable before trusting it.
Key Transparency is inspired by CONIKS and Certificate Transparency. It is a work-in-progress with the following milestones under development.
Key Transparency Client
Setup
- Install Go 1.10.
go get -u github.com/google/keytransparency/cmd/keytransparency-client
Client operations
Generate a private key
keytransparency-client authorized-keys create-keyset -p password
keytransparency-client authorized-keys list-keyset -p password
Publish the public key
- Get an OAuth client ID and download the generated JSON file to
client_secret.json.
keytransparency-client post user@domain.com --client-secret=client_secret.json --insecure -d 'dGVzdA==' #Base64
Get and verify a public key
keytransparency-client get <email> --insecure --verbose

Development and Testing
Key Transparency and its Trillian backend use a MySQL database, which must be setup in order for the Key Transparency tests to work.
