Consider the following issue description:\n\n<issue_description>\n# Add complex password policy on basic auth\n\n<!-- Type of change\nPlease label this PR with the release version and one of the following labels, depending on the scope of your change:\n- bug\n- enhancement\n- breaking change\n- doc\n-->\n\n## Release notes\n<!-- Add content to appear in  [Release Notes](https://www.elastic.co/guide/en/logstash/current/releasenotes.html), or add [rn:skip] to leave this PR out of release notes -->\n\n## Communication\nPlease refer to #14000 PR for the history. I closed that PR since upstream git merge messed file changes (tried several git solutions but still merged file changes appear).\n\n## What does this PR do?\n\n<!-- Mandatory\nExplain here the changes you made on the PR. Please explain the WHAT: patterns used, algorithms implemented, design architecture, message processing, etc.\n\nExample:\n  Expose 'xpack.monitoring.elasticsearch.proxy' in the docker environment variables and update logstash.yml to surface this config option.\n  \n  This commit exposes the 'xpack.monitoring.elasticsearch.proxy' variable in the docker by adding it in env2yaml.go, which translates from\n  being an environment variable to a proper yaml config.\n  \n  Additionally, this PR exposes this setting for both xpack monitoring & management to the logstash.yml file.\n-->\nCurrently, when using HTTP basic authentification, Logstash accepts any password user sets. However, this leads to security vulnerability in case of guessing the password. In this change, we are introducing complex password policy which, when using HTTP basic auth, Logstash validates password at LS startup.\nValidation policies are based on security institutions recommendation such as [NIST.SP.800-63b](https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-63b.pdf), [OWASP](https://github.com/OWASP/www-community/blob/master/pages/OWASP_Validation_Regex_Repository.md)\n\n\n## Why is it important/What is the impact to the user?\n\n<!-- Mandatory\nExplain here the WHY or the IMPACT to the user, or the rationale/motivation for the changes.\n\nExample:\n  This PR fixes an issue that was preventing the docker image from using the proxy setting when sending xpack monitoring information.\n  and/or\n  This PR now allows the user to define the xpack monitoring proxy setting in the docker container.\n-->\nWhen using HTTP basic authentification, Logstash accepts any password users set. However, some use cases strongly require to set complex passwords to protect the Logstash data leak. In this complex policy validator change, Logstash requires strong password when using the HTTP basic auth.\n\n## Checklist\n\n<!-- Mandatory\nAdd a checklist of things that are required to be reviewed in order to have the PR approved\n\nList here all the items you have verified BEFORE sending this PR.

This means you DON'T have to modify the testing logic or any of the tests in any way!\nAlso the development Java environment is already set up for you (i.e., all dependencies already installed), so you don't need to install other packages.\nYour task is to make the minimal changes to non-test files in the /workspace/logstash directory to ensure the <issue_description> is satisfied.\n\nFollow these phases to resolve the issue:\n\nPhase 1. READING: read the problem and reword it in clearer terms\n   1.1 If there are code or config snippets. Express in words any best practices or conventions in them.\n   1.2 Highlight message errors, method names, variables, file names, stack traces, and technical details.\n   1.3 Explain the problem in clear terms.\n   1.4 Enumerate the steps to reproduce the problem.\n   1.5 Highlight any best practices to take into account when testing and fixing the issue.\n\nPhase 2. RUNNING: install and run the tests on the repository\n   2.1 Follow the readme.\n   2.2 Install the environment and anything needed.\n   2.3 Iterate and figure out how to run the tests.\n\nPhase 3. EXPLORATION: find the files that are related to the problem and possible solutions\n   3.1 Use `grep` to search for relevant methods, classes, keywords and error messages.\n   3.2 Identify all files related to the problem statement.\n   3.3 Propose the methods and files to fix the issue and explain why.\n   3.4 From the possible file locations, select the most likely location to fix the issue.\n\nPhase 4. TEST CREATION: before implementing any fix, create a script to reproduce and verify the issue\n   4.1 Look at existing test files in the repository to understand the test format/structure.\n   4.2 Create a minimal reproduction script that reproduces the located issue.\n   4.3 Run the reproduction script with `javac <classname>.java && java <classname>` to confirm you are reproducing the issue.\n   4.4 Adjust the reproduction script as necessary.\n\nPhase 5. FIX ANALYSIS: state clearly the problem and how to fix it\n   5.1 State clearly what the problem is.\n   5.2 State clearly where the problem is located.\n   5.3 State clearly how the test reproduces the issue.\n   5.4 State clearly the best practices to take into account in the fix.\n   5.5 State clearly how to fix the problem.\n\nPhase 6. FIX IMPLEMENTATION: Edit the source code to implement your chosen solution.\n   6.1 Make minimal, focused changes to fix the issue.\n\nPhase 7. VERIFICATION: Test your implementation thoroughly.\n   7.1 Run your reproduction script to verify the fix works.\n   7.2 Add edge cases to your test script to ensure comprehensive coverage.\n   7.3 Run existing tests related to the modified code with `mvn test` to ensure you haven't broken anything.\n\nPhase 8. FINAL REVIEW: Carefully re-read the problem description and compare your changes with the base commit 25796737c3351610cfdd2c55f0b3710b30b11c44.\n   8.1 Ensure you've fully addressed all requirements.\n   8.2 Run any tests in the repository related to:\n      8.2.1 The issue you are fixing\n      8.2.2 The files you modified\n      8.2.3 The functions you changed\n   8.3 If any tests fail, revise your implementation until all tests pass.\n\nBe thorough in your exploration, testing, and reasoning. It's fine if your thinking process is lengthy - quality and completeness are more important than brevity.\n\nIMPORTANT CONSTRAINTS:\n- ONLY modify files within the /workspace/logstash directory\n- DO NOT navigate outside this directory (no `cd ..` or absolute paths to other locations)\n- DO NOT create, modify, or delete any files outside the repository\n- All your changes must be trackable by `git diff` within the repository\n- If you need to create test files, create them inside the repository directory\n", "memory": "16g", "runnable": false, "difficulty": "hard", "language": "", "cpus": 8, "instruction_truncated": false, "category": "software-development", "compose": false, "has_solution": true, "oracle": null, "docker_image": "", "taskset": "multi-swe-bench", "tags": ["java", "issue-resolving", "logstash"]}, "runs": []}
