Sewer is a Let's Encrypt(ACME) client.
It's name is derived from Kenyan hip hop artiste, Kitu Sewer.
PYTHON compatibility: 3.5 is still supported, though I believe at least one driver contains incompatible code (I have no way to actually test it, and sometimes these new features have been backported in 3.x.later). As of 0.8.5 I'm still trying not to break 3.5, but that oldest officially supported version is probably going to take a bump. You already cannot run all the dev tests under 3.5 (black is one obvious one)...
I (maintainer @mmaney) loiter in channel ##sewer (on irc.freenode.net) for those who remember IRC. Don't ask to ask, but waiting is.
- Obtain or renew SSL/TLS certificates from Let's Encrypt
- Supports acme version 2 (current RFC including post-as-get).
- Support for SAN certificates.
- Supports wildcard certificates.
- Bundling certificates.
- Support for both RSA and ECDSA for account and certificate keys.
- Supports DNS and HTTP challenges
- List of currently supported DNS services and BYO-service notes
- HTTP challenges are a new feature, no operational drivers in the tree yet. See usage and BYO-service notes
- sewer is both a command-line program and a Python library for custom use
- Well written(if I have to say so myself):
- Good test coverage
- Passing continuous integration
- High grade statically analyzed code
- type hinting to support mypy verification is a recently begun WIP

- Why another ACME client?
I wanted an ACME client that I could use to programmatically(as a library) acquire/get certificates. However I could not find anything satisfactory for use in Python code. - Why is it called Sewer? I really like the Kenyan hip hop artiste going by the name of Kitu Sewer.
