For more info see simp_le --help.
NOTE: this repository is mostly unmaintained; I will review and merge PRs,
but I(@zenhack) am no longer using this tool myself and am thus not motivated
to otherwise actively develop it.

Project History

@kuba wrote the original https://github.com/kuba/simp_le, at a time when
ACME & let’s Encrypt were very new; certbot still didn’t support nginx,
and there was an un-filled niche for a trivial command line ACME client.
At some point @kuba stopped maintaining simp_le. A few months later bitrot
set in, and PRs fixing the problems went unmerged.
When the breakage began to affect https://zenhack.net, I(@zenhack) forked
the project, merged the PRs, fixed CI and began maintaining the tool. This
continued for several years.
I(@zenhack) switched over to using NixOS’s acme configuration options, and
transitioned the project to its current semi-unmaintained status.



Manifest

UNIX philosophy: Do one thing and do it well!
simp_le --valid_min ${seconds?} -f cert.pem implies that
cert.pem is valid for at at least valid_min (defaults to 2592000
seconds / 30 days). Register new ACME CA account if necessary. Issue
new certificate if no previous key/certificate/chain found. Renew only
if necessary.
(Sophisticated) “manager” for
${webroot?}/.well-known/acme-challenge only. No challenges other
than http-01. Existing web-server must be running already.
No magical webserver auto-configuration.
Owner of ${webroot?}/.well-known/acme-challenge must be able to
run the script, without privilege escalation (sudo, root,
etc.).
crontab friendly: fully automatable - no prompts, etc.
No configuration files. CLI flags as the sole interface! Users
should write their own wrapper scripts or use shell aliases if
necessary.
Support multiple domains with multiple roots. Always create single
SAN certificate per simp_le run.
Flexible storage capabilities. Built-in
simp_le -f fullchain.pem -f key.pem,
simp_le -f chain.pem -f cert.pem -f key.pem, etc.
Do not allow specifying output file paths. Users should symlink if
necessary!
No need to allow specifying an arbitrary command when renewal has
happened, just check the exit code:

0 if certificate data was created or updated;
1 if renewal not necessary;
2 in case of errors.


--server (support multiple ACME v2 CAs).
Support for revocation.
Implicit agreement to the selected ACME CA’s terms of service.

Change Log
Below is a summary of changes introduced in each release. Any user-visible
changes must be recorded here. Note that the topmost entry sometimes
represents the next (i.e. not yet released) version.
Releases occur approximately every two months, unless there is a pressing need
to do otherwise (e.g. security & serious bug fixes), or no changes have been
made since the last release.

0.20.0

Update python-acme dependency to version 2.0



0.19.2

Fix a minor standards conformance issue, see
https://github.com/zenhack/simp_le/pull/155



0.19.1

Add missing dependency on the six package.



0.19.0

Add --use_alt_chain flag.



0.18.1

Fix a minor protocol conformance issue.
Fix some bitrot in the venv.sh script (not applicable unless installing
from the git repo).



0.18.0

Upgrade acme to 1.3 or later.
Fix a bug where simp_le failed to obtain a cert from BuyPass ACME.



0.17.0

Upgrade acme to 1.x



0.16.0

Fix an ACME v2 protocol non-conformity
Upgrade acme to 0.39.x



0.15.0
Please read these carefully, as this release includes a couple changes
that may require changes when upgrading

Switch from ACME v1 to ACME v2 endpoints support.
Support for ACME v1 endpoints has been dropped entirely.
If you were previously passing the server endpoint via the
--server flag, you will need to update it to point to
a v2 endpoint (or simply remove it, to use Let’s Encrypt’s
default v2 endpoint).
Persist account_reg.json in addition to account_key.json, and
recover missing registration info if needed. You will now
need to pass a ``-f account_reg.json`` option to simp_le
Remove the -f external.sh feature.
Drop official support for Python 2 and 3.4.
Add official support for Python 3.7 (in theory it should have
worked before, but we are now testing with it).
Upgrade acme to 0.35.x



0.14.0

Upgrade acme to 0.33.x



0.13.0

Upgrade acme to 0.31.x



0.12.0

Upgrade acme to 0.29.x



0.11.0

Upgrade acme to 0.27.x



0.10.0

Upgrade acme to 0.25.x



0.9.0

Upgrade acme to 0.24.x



0.8.1

Add a workaround for some installation problems caused by a bug in pip.



0.8.0

Drop official support for Python 2.6
Upgrade acme to 0.22.x



0.7.0

Remove the ToS hash comparison, implicitly agree to CA’s ToS if present
Add check for empty or corrupt cert/key files
Add some sanity checks for email syntax
Upgrade acme to 0.20.x



0.6.2

Implement the future-proofing mentioned in the 0.6.1 release notes. Future
TOS changes should not break simp_le >= 0.6.2



0.6.1

Update the hash for the letsencrypt TOS. The TOS changed on November 15th,
which broke previous releases. Future releases will not hard-code the hash,
which should avoid this sort of problem in the future.



0.6.0

Drop official support for Python 3.3.
Disable self-verification; this was highly unreliable and resulted in
spurrious warnings.
Improve argument sanity-checks and error messages.
Save account_key.json, even on failures
Clean temporary challenge files.
Upgrade acme to 0.19.x



0.5.1

Add a workaround for some installation problems caused by a bug in pip



0.5.0

Upgrade acme to 0.17.x



0.4.0

Upgrade acme to 0.16.x



0.3.0

Fix a bug where the version number was incorrectly reported
Upgrade acme to 0.15.x



0.2.0

Upgrade to acme 0.11.x



0.1.1

Change the package name; the original maintainer owns the simp_le PyPI
package, and hasn’t responded to requests to transfer it, so the package name
is now ‘simp_le-client’.



0.1.0

First release
