Uses a 2-year decay window. **Popularity (30%)** — Total and monthly downloads, GitHub stars, and forks. Logarithmic scaling prevents top-heavy scores. **Community (15%)** — Contributors, dependents, forks, watchers, and maintainers. Measures real ecosystem engagement. **Maturity (30%)** — Project age, version count, PHP version support, and release stability. ### Release Activity Cadence Every ~598 days Recently: every ~735 days Total 6 Last Release 94d ago Major Versions 1.2.0 → 2.0.02018-05-13 2.0.1 → 3.0.02025-12-03 PHP version history (3 changes)1.1.0PHP >=5.6 2.0.0PHP ^7.1.3 3.0.0PHP >=8.1 ### Community Maintainers ![](https://www.gravatar.com/avatar/5e83e3701566e43438525ed14578487e732b849d152b5071aa1613a0dad96913?d=identicon)[jdz](/maintainers/jdz) --- Top Contributors [![joffreydemetz](https://avatars.githubusercontent.com/u/15113527?v=4)](https://github.com/joffreydemetz "joffreydemetz (16 commits)") --- Tags cryptutilitiesJDZ ### Code Quality TestsPHPUnit ### Embed Badge ![Health badge](/badges/jdz-crypt/health.svg) ``` [![Health](https://phpackages.com/badges/jdz-crypt/health.svg)](https://phpackages.com/packages/jdz-crypt) ``` ### Alternatives [vaimo/composer-patches Applies a patch from a local or remote file to any package that is part of a given composer project.
