Using letsencrypt with HKPK

Read Original

This technical article explains how to configure HTTP Public Key Pinning (HKPK/RFC7469) with Let's Encrypt's frequently renewed certificates. It details the strategy of pinning intermediate certificates instead of leaf certificates to avoid configuration updates, provides the exact nginx configuration header, and includes commands to generate the required SHA256 hashes from the certificates for verification.
