@le-space/ucanto-principal

@le-space/ucanto-principal provides identity management and cryptographic utilities for UCAN-based authentication and authorization. It enables secure key generation, signing, and verification of UCANs.

What It Provides

• Key Management: Supports cryptographic key generation and handling.
• UCAN Signing & Verification: Ensures authenticity and integrity of UCAN tokens.
• Identity Handling: Manages decentralized identifiers (DIDs) for secure communication.

How It Fits with Other Modules

• @le-space/ucanto-core: Uses principal identities for capability execution.
• @le-space/ucanto-server: Relies on identity verification for secure RPC handling.
• @le-space/ucanto-interface: Defines standard identity-related types.
• @le-space/ucanto-transport: Ensures encrypted and authenticated communication.

For an overview and detailed usage information, refer to the main ucanto README.

Installation

npm install @le-space/ucanto-principal

Example Usage

import { ed25519 } from '@le-space/ucanto-principal';

const keypair = ed25519.generate();
const signature = keypair.sign(new Uint8Array([1, 2, 3]));
const isValid = keypair.verify(new Uint8Array([1, 2, 3]), signature);
