 * [TLS cipher suites][iana_tls_parameters].
 *
 * **Not all cipher suites are supported on all platforms.** As newer cipher suites are created (for
 * stronger privacy, better performance, etc.) they will be adopted by the platform and then exposed
 * here. Cipher suites that are not available on either Android (through API level 24) or Java

Kulcs funkciók:

* **Gyors**: Nagyon nagy teljesítmény, a **NodeJS**-el és a **Go**-val egyenrangú (a Starlettenek és a Pydantic-nek köszönhetően). [Az egyik leggyorsabb Python keretrendszer](#performance).
* **Gyorsan kódolható**: A funkciók fejlesztési sebességét 200-300 százalékkal megnöveli. *
* **Kevesebb hiba**: Körülbelül 40%-al csökkenti az emberi (fejlesztői) hibák számát. *
