SCEP Service Overview

+

+ SCEP (Simple Certificate Enrollment Protocol) allows devices to automatically request and receive certificates from this mkcert Web UI service. + This implementation provides a simplified SCEP server that generates certificates using mkcert. +

+ +
+ Note: This is a simplified SCEP implementation designed for development and testing environments. + For production use, consider a full-featured SCEP server. +
