Description
Legacy PHP 8.0 applications can use TLS, certificates, signatures, hashes, and encrypted data through OpenSSL. This runtime extension is needed by many web apps, mail clients, payment integrations, and API clients that verify peers or protect sensitive traffic. It is dependency-only and has no separate launcher; PHP code calls the OpenSSL functions after the extension is enabled. Administrators should review certificate paths, private key permissions, protocol choices, and trust settings because mistakes can weaken authentication or expose secrets.
