Sewer

Sewer is a Let's Encrypt(ACME) client.
It's name is derived from Kenyan hip hop artiste, Kitu Sewer.

• The stable release is 0.8.4.
• More history (including notes on 0.8.5-to-be) in the CHANGELOG.

PYTHON compatibility: 3.7 and above are tested.

I (maintainer @mmaney) loiter in channel ##sewer (on irc.freenode.net) for those who remember IRC. Don't ask to ask, but waiting is.

Features

• 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

FAQ

• 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.
