## [Unreleased]

## [0.3.0] — 2026-04-24

### Added
- `src/keystore.rs` — AES-256-GCM + Argon2id şifreleme; `save_encrypted` / `load_encrypted` / `prompt_password`
- `nu wallet new`: şifre ister (confirm), private key şifreli JSON olarak `~/.nu/keystore/<label>.key`'e yazar
- `nu wallet address`: şifre ister, decrypt edip compressed public key basar

### Changed
- Keystore formatı plaintext hex'ten JSON (`argon2_hash` + `nonce_hex` + `ciphertext_hex`) formatına geçti
