🔐 Wallet Manager

A secure, CLI tool for generating and organizing hierarchical deterministic (HD) wallets using BIP-39 and BIP-44 standards. Written in Rust for maximum security, it supports seed phrase generation, key derivation, and transaction signing. It prioritizes user privacy, ensuring all cryptographic operations occur locally and securely away from online threats.

• Generates BIP-39 12-word mnemonic phrases
• Derives Ethereum addresses from mnemonic
• Encrypts mnemonic with AES-256-GCM using a user-provided password
• Key derivation via Keccak-256 with random salt
• Saves/loads encrypted wallet from a local JSON file

• Mnemonic is encrypted at rest using AES-256-GCM
• Password never stored — only used to derive the encryption key
• Random salt and nonce generated per encryption

• ethers — Wallet derivation, Keccak-256 hashing
• aes-gcm / aead — AES-256-GCM encryption
• bip39 — Mnemonic generation
• rpassword — Secure password input (hidden from terminal)
• serde / serde_json — JSON serialization
