Ghostkey Library (ghostkey_lib)

A Rust library for creating and managing ghost keys and certificates in the Freenet ecosystem.

Features

• Creation and verification of delegate certificates
• Creation and verification of ghost key certificates
• RSA and Ed25519 cryptographic operations
• Serialization and deserialization of certificates

Main Components

• DelegateCertificateV1: Represents a delegate certificate signed by a master key
• GhostkeyCertificateV1: Represents a ghost key certificate signed by a delegate key
• Armorable: Trait for serializing and deserializing objects to/from bytes and armored strings

Usage

Add this to your Cargo.toml:

[dependencies]
ghostkey_lib = "0.1.2" # Replace with the latest version

Example usage:

use ghostkey_lib::{DelegateCertificateV1, GhostkeyCertificateV1, util::create_keypair};
use rand_core::OsRng;

// Create a master key pair
let (master_signing_key, master_verifying_key) = create_keypair(&mut OsRng).unwrap();

// Create a delegate certificate
let info = "Test Delegate".to_string();
let (delegate_certificate, delegate_signing_key) =
    DelegateCertificateV1::new(&master_signing_key, &info).unwrap();

// Create a ghost key certificate
let (ghost_key_certificate, ghost_key_signing_key) =
    GhostkeyCertificateV1::new(&delegate_certificate, &delegate_signing_key);

// Verify the ghost key certificate
let verified_info = ghost_key_certificate
    .verify(&Some(master_verifying_key))
    .unwrap();
assert_eq!(verified_info, info);
