[github-actions]

👋 Hello! Thanks for contributing to our project.
Acceptance tests will take some time (aprox. 1h), please be patient ☕
You can see the progress at the end of this page and at https://github.com/uyuni-project/uyuni/pull/9475/checks
Once tests finish, if they fail, you can check 👀 the cucumber report. See the link at the output of the action.
You can also check the artifacts section, which contains the logs at https://github.com/uyuni-project/uyuni/pull/9475/checks.

If you are unsure the failing tests are related to your code, you can check the "reference jobs". These are jobs that run on a scheduled time with code from master. If they fail for the same reason as your build, it means the tests or the infrastructure are broken. If they do not fail, but yours do, it means it is related to your code.

Reference tests:

• https://github.com/uyuni-project/uyuni/actions/workflows/acceptance_tests_secondary_parallel.yml?query=event%3Aschedule

• https://github.com/uyuni-project/uyuni/actions/workflows/acceptance_tests_secondary.yml?query=event%3Aschedule

KNOWN ISSUES

Sometimes the build can fail when pulling new jar files from download.opensuse.org . This is a known limitation. Given this happens rarely, when it does, all you need to do is rerun the test. Sorry for the inconvenience.

For more tips on troubleshooting, see the troubleshooting guide.

Happy hacking!
⚠️ You should not merge if acceptance tests fail to pass. ⚠️

Math.random() is a pseudorandom number generator, I don't think we want to use it here. Similarly below in the sort function, I think this is not the way we want to approach this. The whole idea of using window.crypto.getRandomValues() is that we don't want to use Math.random().

I think this is not true? Using a fixed length reduces security, since it makes the space you need to brute force smaller. To exemplify, if we use only passwords of length 25, then there are X^25 combinations where X is the number of symbols in our charset, but if we allow for example passwords of length 15-25, then there are X^15 + X^16 + X^17 + ... + X^25 combinations.

[Etheryte]

I think we need to revisit this code, I don't think as is this is a correct way to generate passwords. Is there a ticket behind this change, what are the requirements?

Also pinging @szachovy for opinions, I think this is something up your alley.
