Project State
Project Reference
See: .planning/PROJECT.md (updated 2026-02-25)
Core value: Archive impossible to unpack without knowing the format -- standard tools (7z, tar, unzip, binwalk) cannot recognize or extract contents Current focus: Phase 12 COMPLETE -- All key input methods functional
Current Position
Phase: 12 of 12 (User Key Input) -- COMPLETE Plan: 2 of 2 -- COMPLETE Status: Phase 12 complete, all three key input methods (--key, --key-file, --password) functional Last activity: 2026-02-26 -- Phase 12 Plan 02 executed (Argon2id KDF + salt format)
Progress: [####################] 100% (15/15 plans complete)

Accumulated Context
Decisions
Decisions are logged in PROJECT.md Key Decisions table. Recent decisions affecting current work:
- v1.0: IV stored only in TOC, not duplicated in data blocks
- v1.0: Manual binary serialization with to_le_bytes/from_le_bytes (no serde/bincode)
- v1.0: Filename-only entry names -- v1.1 changes this to relative paths with
/separator - v1.0: Always enable all 3 obfuscation features (no flags)
- v1.0: Two-pass TOC serialization for correct data_offsets with encrypted TOC size
- v1.1: No backward compatibility with v1.0 archives (format version bump)
- v1.1: Only mode bits (no uid/gid, no timestamps, no symlinks)
- v1.1: entry_type and permissions fields placed AFTER name, BEFORE original_size in TOC entry
- v1.1: Directory entries use zero-filled crypto fields (uniform entry structure)
- v1.1: Entry size formula: 104 + name_length (was 101)
- v1.1: DFS preorder with sorted children for deterministic parent-before-child ordering
- v1.1: Extracted crypto pipeline into process_file() helper for reuse
- v1.1: Directory entries skip data_offset computation (offset=0, no ciphertext)
- v1.1: Permissions stored as lower 12 bits of mode_t (0o7777 mask)
- v1.1: Kotlin decoder uses Java File API owner/everyone permission model (no group-level granularity)
- v1.1: Directory entries in Kotlin decoder skip crypto pipeline entirely, use mkdirs()
- v1.1: Permission application order: everyone flags first, then owner-only overrides
- v1.2: KeyArgs as top-level clap flatten (--key before subcommand)
- v1.2: inspect accepts optional key: without key shows header only, with key shows full TOC
- v1.2: LEGACY_KEY kept as #[cfg(test)] for golden test vectors
- v1.2: All archive functions parameterized by explicit key (no global state)
- v1.2: Two-phase key resolution: resolve_key_for_pack() generates salt, resolve_key_for_unpack() reads salt from archive
- v1.2: Salt stored as 16 plaintext bytes between header and TOC, signaled by flags bit 4 (0x10)
- v1.2: Argon2id with default parameters for password-based key derivation
- v1.2: Pack prompts password twice (confirmation), unpack prompts once
Pending Todos
None yet.
Roadmap Evolution
- Phase 12 added: User-specified encryption key (--password, --key, --key-file)
Blockers/Concerns
None.
