DKIM Key Pair Generator

Generates a real DKIM key pair using your browser's built-in Web Crypto API. The private key is generated and stays entirely in this browser tab. It is never sent anywhere. Refreshing or closing this page discards it, so save it somewhere safe before you leave.

Why not just check my current DKIM record?

This tool generates a brand-new key pair for you to publish. To check whether a DKIM record you've already published is valid, use the main domain scanner instead. Enter your selector there and it'll look up and validate the live record.
