I've been working on a client for ACME cert managemnet
protocol, RFC8555. It's what letsencrypt uses, as well
as several other providers.
It works, though there are probably a few tweaks to be
done before it gets committed, and we should figure out
how to get DNS challenges working.
The code is here until I commit it to 9front:
http://shithub.us/ori/aclient/HEAD/info.html
Before committing:
- I'd like to figure out a way to add a way to
add a script to handle the challenge, without
making the program clunky.
- I'd like add support for DNS challenges.
- I think the default locations may not be
ideal, and I'd like to see if there are
better options.
- Get a round of review and thoughts on what
it should do differently.
- Maybe rename it to honest/acmed -- Honest
Acmed's guaranteed-unsketchy used cert
emporium and underwear store.
But it's there, and it works.
Manpage below:
ACLIENT(8) ACLIENT(8)
NAME
aclient - acme certificate client
SYNOPSIS
aclient [ -o outdir ] [ -p provider ] [ -a acctkey ] [ c
csrkey ] [ w chaldir ] acctname domain
DESCRIPTION
Aclient fetches and renews TLS certificates using the acme
protocol. It requires a pregenerated account key and cer-
tificate signing key.
There are a number of options.
-o outdir Specifies that the signed certificate is placed
in outdir in place of the default /sys/lib/tls/acme/.
-p provider Specifies that provider is used as the pro-
vider URL, in place of the default https://acme-
v02.api.letsencrypt.org/directory. This must be the
directory URL for the desired RFC8555 compliant pro-
vider
-a acctkey Specifies that acctkey is used to sign requests
to the provider in place of the default
/sys/lib/tls/acme/$acctname.pub. The key must be a jwk
formatted RSA key.
c csrkey Specifies that csrkey is used to produce the CSR
sent to provider in place of the default
/sys/lib/tls/acme/$domain.key. The key must be a plan 9
formatted RSA key suitable for aux/rsa2csr.
w chaldir Specifies that the challenge is written out to
chaldir. For HTTP challenges, this defaults to
/usr/web/.well-known/acme-challenge/.
EXAMPLES
Before aclient is run, the keys must be generated.
auth/rsagen -t 'service=acme role=sign hash=sha256 acct=me@example.org' |
tee /sys/lib/acme/me@example.org.priv |
auth/rsa2jwk > /sys/lib/acme/me@example.org.pub
auth/rsagen -t 'service=tls owner=*'
>/sys/lib/acme/mydomain.com.key
This need only be run once. Once the keys are generated,
they should be loaded into factotum:
cat /sys/lib/acme/mydomain.com.key >/mnt/factotum/ctl
cat /sys/lib/acme/me@example.org.priv >/mnt/factotum/ctl
The certificate for the domain can now be fetched:
aclient me@example.org mydomain.com
SOURCE
/sys/src/cmd/$somewhere/aclient.c
BUGS
Aclient only supports HTTP challenges that placed in static
directories. It should add support for DNS challenges, and
provide a way for a script to be invoked while handling
them.

ironically, instead of acme doing everything, we now have everything being called acme.
maybe consider /sys/lib/tls/aclient instead of /sys/lib/tls/acme?*
* I assume the scattered references to /sys/lib/acme were meant to be /sys/lib/tls/acme.

That is ironic.
Perhaps a foolish thought, but I'll suggest anyway: what if it were
named after the RFC it implements (e.g., /bin/rfc8555/client )?
Boring, but transparent.

Yep. Fixed, and changed to acmed instead of
acme or aclient.
