# Install certbot with Homebrew, apk, apt, dnf, MacPorts, Nix, pacman, winget, zypper Tool to obtain certs from Let's Encrypt and autoenable HTTPS. Version 5.6.0 via Homebrew; verified 2026-05-20. ## Install ```sh sudo av install brew:certbot ``` ## Agent safety answer certbot manages TLS certificates and can change web-server certificate state. - **Credential access:** Reads account keys, private keys, webroot paths, and DNS provider credentials. - **Remote mutation:** Can request certificates and modify local server config or DNS plugins. - **Publish/artifact risk:** Can create certificates used by public services. - **Recommended control:** Gate renew, certonly, private-key reads, and DNS credential use. - **Agent-use guidance:** Allow certificate status checks; require approval before issuing, renewing, or editing live certs.

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. ### Adoption history 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. ### How it is used 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. ### Why package nerds care 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. ### Timeline - 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. ### Sources - - - - - - - - ## Security Notes No matching local secret-handling manifest was found for certbot. Nucleus package metadata is still published here so future coverage has a stable package URL. ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials. Automic Vault can use them as review targets for secret scanning, migration, and command approval. ## Credential files - macOS: ~/Library/Application Support/letsencrypt - Unix: ~/.config/letsencrypt, ~/.letsencrypt ## Source Database Details -
