## プロジェクトの歴史と使われ方

TrueCrack is a GPLv3 brute-force password cracker for TrueCrypt volumes. The official README identifies version 3.6, Linux support, CUDA optimization, and both GPU and CPU execution.

### プロジェクトの歴史

TrueCrack belongs to the older TrueCrypt-era password-recovery and forensic tooling niche. Its README says the software is based on TrueCrypt and supports PBKDF2 key derivation functions using RIPEMD160, SHA512, and Whirlpool, plus XTS mode with AES, Serpent, and Twofish.

The project is intentionally focused rather than broad: it handles file-hosted and partition/device-hosted TrueCrypt volumes, hidden volumes, backup headers, dictionary attacks, and generated alphabet attacks. The README's performance section compares CPU and NVIDIA GPU timings, reflecting the period when CUDA acceleration was a major differentiator for brute-force recovery tools.

### 採用の歴史

Reliable source-backed adoption evidence is thin beyond the official repository and package-manager presence. The Homebrew and Nix packages make the tool discoverable to security practitioners and collectors of legacy crypto/password tools, but the project itself documents a narrow, resource-heavy workflow and recommends a dedicated GPU board.

In package-manager catalogs, TrueCrack persists mostly as a specialized utility: useful when someone needs TrueCrypt-volume password recovery experiments, but not a general password-auditing framework.

### 使われ方

The README documents dictionary attacks with `truecrack -t truecrypt_file -w passwords_file` and alphabet attacks with `truecrack -t truecrypt_file -c alphabet -m maxlength`, with options for key derivation function, encryption algorithm, backup headers, hidden volumes, restore points, and CUDA/CPU configuration.

Build and installation follow the classic Autotools path: `./configure`, `make`, and `sudo make install`, with configure options for CUDA debug mode, CPU-only mode, and CUDA path selection.

### パッケージ好きにとっての重要性

TrueCrack is package-nerd-significant as a preserved C/CUDA security tool tied to the TrueCrypt ecosystem. It is the kind of package that matters less for daily use and more for keeping a historically important crypto-recovery workflow buildable from package managers.

Its formula is also a reminder that package collections include legacy forensic utilities whose upstream documentation is sparse but operationally specific.

### タイムライン

- v3.6: The README identifies the project as TRUECRACK v3.6.
- TrueCrypt basis: README says the software is based on TrueCrypt and targets TrueCrypt volumes.
- Current README: documented usage includes dictionary attacks, generated alphabet attacks, GPU/CPU operation, hidden volumes, backup headers, and Autotools installation.
