DID Manager

The DID Manager is a modern Decentralized Identifier (DID) management system built with Golang and PostgreSQL. It supports the creation, signing, and management of DIDs and their attributes using Ed25519 cryptography. The project complies with W3C DID standards, providing a robust API and intuitive web interface.

Features

• Generate Decentralized Identifiers (DIDs) with deterministic UUIDv5.
• Sign and Verify Attributes securely using Ed25519 keys.
• List DIDs and Attributes with all signatures.
• Secure Storage of private keys and DIDs in PostgreSQL.
• Fully responsive Web Frontend with TailwindCSS.
• API Endpoints for programmatic access to DID operations.
• HTTPS support with Let’s Encrypt TLS certificates.
