Sodot MPC

The Sodot MPC provides a secure and efficient implementation of threshold cryptography using multi-party computation (MPC). This SDK enables distributed key generation and signing for various cryptographic schemes without requiring a trusted dealer.

Key Features

• Threshold Key Generation: Generate cryptographic keys across multiple parties
• Distributed Signing: Sign messages collaboratively without exposing private keys
• Key Refresh: Update secret shares while maintaining the same public key
• Multiple Schemes: Support for ECDSA, Ed25519, BIP340, and SR25519
• Secure MPC: All operations use secure multi-party computation protocols

Basic Usage

use sodot_mpc::{KeygenId, KeygenPrivateKey, RoomUUID};

// Create types for MPC operations
let keygen_id = KeygenId::new("2WpjFqPh8TqQKqZKZXgW8a".to_string());
println!("Party ID: {:?}", keygen_id);

// Create a private key from bytes
let key_bytes = [1u8; 32]; // Example 32-byte array
let private_key = KeygenPrivateKey::new(key_bytes);
println!("Private key created: {:?}", private_key);

// Create a room UUID
let room_uuid = RoomUUID::new("550e8400-e29b-41d4-a716-446655440000".to_string());
println!("Room UUID: {:?}", room_uuid);
