- **リモート変更:** Can request certificates and modify local server config or DNS plugins.
- **公開/成果物リスク:** Can create certificates used by public services.
- **推奨コントロール:** Gate renew, certonly, private-key reads, and DNS credential use.
- **エージェント利用ガイダンス:** Allow certificate status checks; require approval before issuing, renewing, or editing live certs.

## プロジェクトの歴史と使われ方

Certbot is EFF's ACME client for obtaining and renewing HTTPS certificates, most commonly from Let's Encrypt, and optionally configuring web servers such as Apache and nginx.

### プロジェクトの歴史

The repository was created in 2014 during the early Let's Encrypt client era. In 2016, EFF announced the client would move under the Certbot name to distinguish the client from the Let's Encrypt certificate authority and ISRG organization.

### 採用の歴史

Certbot rode the same adoption wave as Let's Encrypt: EFF's 2016 announcement noted Let's Encrypt had issued its three millionth certificate, and EFF later reported Certbot installed on more than 4 million web servers maintaining certificates for more than 31 million websites.

### 使われ方

Certbot is intended to run on the server that hosts the site. It obtains certificates, saves them under /etc/letsencrypt/live, renews them on a schedule, and can use plugins for Apache, nginx, webroot, standalone, manual, and DNS-based validation.

### パッケージ好きにとっての重要性

Certbot is one of the canonical examples of a security CLI becoming distribution infrastructure: it appears in many package managers, replaced the older letsencrypt command name in user documentation, deprecated certbot-auto, and standardized operational files under /etc/letsencrypt.

### タイムライン

- 2014: Public certbot/certbot repository created.
- 2016: EFF announced the Let's Encrypt client rename to Certbot and the new certbot.eff.org site.
- 2025: Certbot 5.0.0 released, removing older deprecated APIs and Python 3.9 support.
- 2026: Certbot 5.6.0 released according to the official changelog.

### Related projects

- Let's Encrypt is the default certificate authority commonly used with Certbot.
- ACME is the protocol Certbot speaks, standardized as RFC 8555.
- certbot-apache, certbot-nginx, and Certbot DNS plugins provide authenticator and installer integrations.
