It consists of a raw implementation of the Let's Encrypt ACME protocol. > If you want to chat with us or have questions, ping @tgalopin or @jderusse on the [Symfony Slack](https://symfony.com/support)! When use Acme PHP Core? ----------------------- [](#when-use-acme-php-core) You usually will want to use either [the Acme PHP CLI client](https://github.com/acmephp/cli)or [an implementation for your application framework](https://github.com/acmephp). However, in some cases, you may want to manage SSL certificates directly from your application. In these cases, this library will be useful to you. Acme PHP Core does nothing more than implementing the [Let's Encrypt/ACME protocol](https://github.com/letsencrypt/acme-spec) : the generated SSL keys and certificates are stored in memory and returned to your script. You are the one in charge of storing them somewhere persistent. Documentation ------------- [](#documentation) Read the official [Acme PHP documentation](https://acmephp.github.io). Launch the Test suite --------------------- [](#launch-the-test-suite) The Acme PHP test suite is located in the main repository: . ### Health Score 29 — LowBetter than 59% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity6 Limited adoption so far Community15 Small or concentrated contributor base Maturity68 Established project with proven stability Bus Factor2 2 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
