Thank you for taking the time to work on a PR for Awesome-Sysadmin!

To ensure your PR is dealt with swiftly please check the following:

• Your additions are Free software
• Software your are submitting is not your own, unless you have a healthy ecosystem with a few contributors (which aren't your sock puppet accounts).
• Submit one item per pull request. This eases reviewing and speeds up inclusion.
• Format your submission as follows, where Demo and Clients are optional.
  Do not add a duplicate Source code link if it is the same as the main link.
  Keep the short description under 80 characters and use sentence case
  for it, even if the project's webpage or readme uses another capitalisation.
  Demo links should only be used for interactive demos, i.e. not video demonstrations.
  - [Name](http://homepage/) - Short description, under 250 characters, sentence case. ([Demo](http://url.to/demo), [Source Code](http://url.of/source/code), [Clients](https://url.to/list/of/related/clients-or-apps)) `License` `Language`
• Additions are inserted preserving alphabetical order.
• Additions are not already listed at awesome-selfhosted
• The Language tag is the main server-side requirement for the software. Don't include frameworks or specific dialects.
• You have searched the repository for any relevant issues or PRs, including closed ones.
• Any category you are creating has the minimum requirement of 3 items.
• Any software project you are adding to the list is actively maintained.
• The pull request title is informative, unlike "Update README.md".
  Suggested titles: "Add aaa to bbb" for adding software aaa to section bbb,
  "Remove aaa from bbb" for removing, "Fix license for aaa", etc.

Please take some time to answer the following questions as best you can:

• Why is it awesome?

PKi is not awesome but needed

• Have you used it? For how long?

I have used all of them at least in a lab environment, there are more missing on the list, but they're also not noteworthy :)

• Is this in a personal or professional setup?

I work on related stuff and security is a strange hobby

• How many devices/users/services/... do you manage with it?

~100

• Biggest pros/cons compared to other solutions?

  • openxpki
    • Pro: stable, provides many protocols
    • Cons: dont know any
  • TinyPKI
    • Pro: no configuration needed
    • Cons: Only file based, no HSM support

• Any other comments about your use case, things you've found excellent, limitations you've encountered... ?

• tinyPKI: first commit in august 2023, needs to be more mature and widely tested to qualify for inclusion in the list
• tinyPKI: submitting your own software is discouraged
• multiple items submitted in the same PR, despite guidelines asking not to do so
• insufficient answers to the list of questions (check previously merged PRs for examples of "good" answers)
• lab/testing environments are an essential part of a proper production setup, however software listed here is expected to also fit actual production use cases

In light of all this, closing. Feel free to send a PR that only adds openxpki. Thanks
