## プロジェクトの歴史と使われ方

Monkeysphere is a security tool from the OpenPGP and Debian-adjacent world that tries to bring the OpenPGP web of trust to SSH and TLS authentication. Its README frames the project as extending OpenPGP's trust model to more areas of the Internet, with an implementation that lets users keep using OpenSSH while identifying users and servers through OpenPGP keys managed by GnuPG.

### プロジェクトの歴史

The project was written by Jameson Rollins and Daniel Kahn Gillmor, according to the monkeysphere(7) manual page. Early changelog entries from 2008 show rapid work on server diagnostics, key expiration, certifier management, privilege separation, OpenSSH known_hosts and authorized_keys handling, and Debian packaging, which fits its role as a glue layer around GnuPG and OpenSSH rather than a replacement protocol.

### 使われ方

Administrators use Monkeysphere to bind human-readable OpenPGP user IDs to SSH keys and host identities. The tools update authorized_keys and known_hosts after checking key validity, expiration, revocation, authentication-capable subkeys, and signatures from trusted identity certifiers. That makes its package-manager niche a specialized PKI bridge for people who already trusted OpenPGP key signing and wanted that trust graph to govern SSH host verification or user login access.
