module OpenSSL::SSL

Verwenden Sie SSLContext, um die Parameter für eine TLS-Verbindung (früher SSL) einzurichten. Sowohl Client- als auch Server-TLS-Verbindungen werden unterstützt. SSLSocket und SSLServer können in Verbindung mit einer Instanz von SSLContext verwendet werden, um Verbindungen einzurichten.
