Crate p47h_open_core 

p47h-open-core

Cryptographic primitives and policy engine for secure identity management.

This crate provides a unified API for the P47H ecosystem’s core functionality:

• Identity Management: Ed25519 key generation and DID resolution
• Policy Engine: Pure RBAC/ABAC authorization without external dependencies
• WASM Engine: The core logic for browser-based vault operations

Quick Start

use p47h_open_core::identity::Identity;

// Generate a new cryptographic identity
let mut rng = rand::thread_rng();
let identity = Identity::generate(&mut rng).expect("Failed to generate identity");
println!("Public key hash: {:?}", identity.public_key_hash());

Architecture

This facade crate re-exports the following modules:

• identity - Ed25519 identity management (from core-identity)
• policy - Authorization policy engine (from core-policy)
• engine - WASM-ready vault engine (from p47h-engine)

Feature Flags

• wasm - Enable WebAssembly-specific optimizations (coming soon)

Security

All cryptographic operations use audited, production-ready libraries:

• Ed25519 signatures via ed25519-dalek
• Argon2id key derivation via argon2
• XChaCha20-Poly1305 encryption via chacha20poly1305
• Memory zeroization via zeroize
