SecretShop: a small Gemini server.

Features

Multi-site hosting
Also supports simple Gopher hosting
Fully compliant with Jetforce diagnostics
Client Certificates
Probably won't kill your computer

Where to get it

git clone https://git.saintnet.tech/stryan/secretshop.git

I also release binaries at https://build.opensuse.org/project/show/home:stryan

The release tab also has pre-generated archives if you don't want to run master.

Configuration

SecretShop looks in it's current running directory and /etc/secretshop for it's config file. Configuration is in a file labeled "config.yaml" in one of the above directories. See the sample config for more details.

A standard file looks like such:

---
port: 1965
active_capsules:
        - localhost
localhost:
        Hostname: "localhost"
        Port: "1965"
        RootDir: "/var/gemini"
        CGIDir: "/var/gemini/cgi"
        KeyFile: "localhost.key"
        CertFile: "localhost.crt"
	AccessControl:
		Identified:
			- /id
                Known:
	                - /known
		Trusted:
			- /private
                Whitelist: "whitelist"

Where each "active_capsule" is a virtual Gemini capsule. SecretShop supports virtual Gemini capsules all listening on port 1965.

By default, a capsule requires the Hostname, Root Directory, Keyfile, and CertFile to start properly. The capsule also needs to be listed in the "active_capsules" list. Each capsule can optionally have a "AccessControl" section for use with client certificates. AccessControl is broken up into three zones: Identified: Requires a client to present a certificate of some kind to access. Currently not validate certificate. Response code 60 Known: Reserved for transient certificates; currently not fully implemented. Reponse code 61 Trusted: Requires a client to present a certificate who's fingerprint matches an entry in the Whitelist file. Currently checks validity dates and the fingerprint. Response codes 62-65

For the Trusted zone, a Whitelist section must exist, with a path leading to the whitelist file. The whitelist file is a text file containing Certificate fingerprints, one for line. This is used to authenticate client certificates.

If you want full logging (i.e. you're not using systemd, rsyslog, something that auto adds timestamps and program names etc) you can add the "full_logging: true" option.

Building

Build Dependencies: go1.14

Running "make" should work for any given x86 machine.

If you're planning on running this on a Raspberry Pi or other ARM machine try env GOOS=linux GOARCH=arm GOARM=5 make

Installation

Running "make install" will install to /usr//bin by default and will attempt to install the systemd service file

Uninstall

Run "make uninstall".

Running

Either run the executable directly or use the Systemd unit file.

Caveats

Currently does not support transient certificates Only handles whitelisting for certificate authorization
