TOC

1. Intro: The idea behind this research
   • signing transactions locally;
   • integration with telegram bot — add new accounts to Ethelia public node.
2. What is the Ethereum (Web3) keystore file;
   • overview;
   • actual scope (real world tasks):
     • Tools (aka hacks) to get private key from keystore file;
     • Importing new accounts (private keys) into Geth client.
3. Implementation in Raku
   • Initial state (it looks promising):
     • libscrypt via Crypt::LibScrypt;
     • AES128-CTR algo via Gcrypt and OpenSSL;
     • UUID;
   • Problems (are on the most important steps);
   • Let's raise a few Pull Requests
     • Crypt::LibScrypt;
     • my new modules as intermediate step.
   • Yet another binding for GNU Libgcrypt;
   • Upgrade Bitcoin::Core::Secp256k1.
4. Node::Ethereum::KeyStore::V3
   • Quick start;
   • ethkeystorev3-cli utility;
   • Dependencies.
5. Afterword
   • Ethelia service;
   • Registering via Telegram Bot;
   • Demo pitch
