409 | 410 | ### FAQs 411 | 412 | #### Why look into "reproducibility"? 413 | 414 | We believe the strategy of leveraging reproducible builds for the purpose of associating artifacts with a source/repository outperforms the current provenance strategy with the added benefit of being backwards compatible. 415 | 416 | #### Will reproducibility get better with time? 417 | 418 | Yes. As we add more strategies, we should see the percentatge of reproducible packages grow over time both net-new & previously published packages will benefit from the additional strategies. Feel free to contribute! 419 | 420 | ### Credits 421 | 422 | Big thanks to [@siddharthkp](https://github.com/siddharthkp) for gifting the package name `reproduce` to us! 423 | 424 | ### Learn More 425 | 426 | We wrote a blog post about this project & the results we found which you can read here: https://blog.vlt.sh/blog/reproducibility 427 | 428 | Is your package reproducible? 429 | -------------------------------------------------------------------------------- /SECURITY.md: -------------------------------------------------------------------------------- 1 | # Security Policy 2 | 3 | ## Reporting a Vulnerability 4 | 5 | If you discover a security vulnerability within this project, please send an email to the repository owner.
