KeyPub.sh is a service that allows users to link their SSH public keys to email addresses, providing a verified identity for all SSH-based applications. Users can register their keys with an email address, control what information is public or private, and reference other users by email or key fingerprint. The service is privacy-focused, with a simple email verification process and no installation or configuration needed. It is a lightweight alternative to OAuth for CLI applications, allowing users to use their existing SSH keys. KeyPub.sh puts users in control of their privacy and provides a central identity system for SSH applications.
