keycase_core

Shared Dart package for the KeyCase ecosystem.

Provides cryptographic identity primitives used by both the KeyCase server and the Keybae client:

• Models — Identity, Proof, KeyPair
• Crypto — Ed25519 signing, NaCl encryption (via libsodium FFI)
• Proof verification — DNS proofs, URL proofs, key signing (web of trust)

Usage

# pubspec.yaml
dependencies:
  keycase_core:
    git:
      url: https://github.com/keycase/core.git

import 'package:keycase_core/keycase_core.dart';

final identity = Identity(
  username: 'alice',
  publicKey: 'Ed25519:base64...',
  createdAt: DateTime.now(),
);
