Decentralized X.509 Certificate Management on XRPL

This project enables decentralized, tamper-resistant, and publicly verifiable digital certificate management using the XRP Ledger (XRPL). By hashing the user's email as a unique identifier, certificates are securely stored and can be retrieved for secure messaging, email encryption, or identity verification—without relying on a central authority. Organisations such as universities, schools, and companies can leverage this system to issue X.509 certificates to their staff and students at zero cost. This removes traditional barriers and expenses, making it possible to build a truly global, blockchain-based Public Key Infrastructure (PKI) that is accessible to all.
