## プロジェクトの歴史と使われ方

Enchive is a small personal-file encryption tool for archiving files to yourself. Its README positions it as a focused alternative to larger systems such as GnuPG or encrypted filesystems, with no external dependencies and portability prioritized over performance.

### プロジェクトの歴史

The public repository dates to 2017, and the project's own documentation frames it as intentionally self-contained rather than ecosystem-seeking. It uses public-key style archival: a public key can encrypt files on machines that should not hold the secret key, while the secret key is needed for extraction.

### 採用の歴史

Enchive's README explicitly says it does not need critical mass because it does not need to interoperate with other systems or people. Its adoption story is therefore narrow by design: it appeals to users who want a copyable, auditable CLI for personal encrypted archives rather than a shared standard.

### 使われ方

The documented workflow has three core commands: `keygen`, `archive`, and `extract`. By default, `keygen` writes `enchive.pub` and `enchive.sec` under `$XDG_CONFIG_HOME/enchive` or `~/.config/enchive`; archiving produces a `.enchive` file while leaving the original in place unless deletion is requested.

The tool also supports deriving an asymmetric key pair from a passphrase, using an scrypt-like memory-hard derivation scheme, and can run a short-lived key agent on Unix-like systems to avoid repeated passphrase prompts.

### パッケージ好きにとっての重要性

Enchive is package-nerd interesting because it is deliberately small: one CLI, no external dependencies, a documented file format, and a build that can produce a standalone C program. It represents the opposite end of the packaging spectrum from large crypto suites.

The tradeoff is visible in the README: Enchive is not trying to be a universal format or social web of keys. It is for users who want a simple local archival workflow and are comfortable choosing a niche tool for that job.

### タイムライン

- 2017: Public GitHub repository created.
- 2018: Published manual page generated for Enchive.
- 2025: Repository remained updated, according to available GitHub metadata.

### Related projects

- GnuPG and encrypted filesystems are named by the README as more complex alternatives.
- Curve25519, ChaCha-family encryption, HMAC-SHA256, and an scrypt-like key derivation algorithm are documented implementation pieces.
