Inca

Inca stands for INternal CA, and it's primary aim is self-explained: handling certificate-wise flows with regards to a local and private CA. On the flip side, its ambitious vocation is to eliminate all the complexity on maintaining a PKI within a company.

Alternatives

Alternatives to Inca that don't have all the required features:

OpenXPKI
EJBCA
step-ca
Locksmith
Certbot - The recommended LetsEncrypt client
Lego - Let's Encrypt client and ACME library written in Go

Internal CA

Given a CA keypair, Inca exposes a set of endpoints usable to interact with the aforementioned CA to issue, revoke, extend valid certificates.

Proxying to other CAs

If configured to do so, Inca can proxy the already mentioned requests to external providers (e.g. Let's Encrypt), providing a simple and common interface for certificates regardless of their origin.

Storing certificates

Inca does not only issue certificates, it caches and stores them on a configurable storage (e.g. locally on filesystem, on S3), reusing them if asked to.

Foreign certificates

Through the webgui, Inca allows for certificates to be manually imported, if issued via a third-party flow.

Self-explanatory API endpoints

Given it's minimal semantic, Inca is super easy to integrate into third-party tools, as obtaining a valid certificate is as easy as curl https://inca.domain.tld/whatever-cn.domain.tld.

Either

go build
go install
inca --help

docker run -it -v --network host ${PWD}/inca.yml:/etc/inca:ro \

Usage

If you're curl-ninja enough:

alias curl='curl -H "Authorization:Bearer REDACTED"'
# fetch certificate
curl https://inca.domain.tld/domain.tld.farm -o whatever.domain.tld.pem
# fetch certificate with further params
curl https://inca.domain.tld/whatever-with-details.domain.tld?alt=whatever2.domain.tld&duration=2y
# fetch key
curl https://inca.domain.tld/whatever.domain.tld/key -o whatever.domain.tld.key
# remove certificate
curl -X DELETE https://inca.domain.tld/whatever.domain.tld

Otherwise, just open Inca on a browser.

Custom installation

inca gen -n domain.tld -o /etc/inca.d
cat >/etc/inca <<EOF
