From c647f3a90eb0927dab465b53e19953bc82afaf0d Mon Sep 17 00:00:00 2001 From: NikitolProject Date: Tue, 24 Feb 2026 23:56:09 +0300 Subject: [PATCH] feat(02-01): project scaffolding with Cargo, CLI skeleton, and key module - Initialize Rust project with aes, cbc, hmac, sha2, flate2, clap, rand, anyhow dependencies - Add clap derive CLI with pack/unpack/inspect subcommands - Add hardcoded 32-byte AES-256 key constant - Create stub modules for format, crypto, compression, archive - All 7 source files in place, cargo build succeeds Co-Authored-By: Claude Opus 4.6 --- Cargo.lock | 479
