What is duraconf?

Duraconf is a collection of ready-to-use configuration files designed to make SSL/TLS services, the technology that encrypts connections between a website and its visitors, more secure. Instead of researching which encryption settings are safe and writing those rules from scratch, you can use these pre-built files as a starting point for your own servers. The project works by providing recommended "cipher lists," which are essentially ranked menus of encryption methods a server will accept. The README walks through different strategies for choosing these lists: you can be very specific about what is allowed, let your encryption software make general decisions for you, or mix both approaches. The guide also explains the importance of Perfect Forward Secrecy (PFS), a property that ensures even if an attacker steals a server's private key, they cannot retroactively decrypt previously recorded traffic. PFS does require more computing power, so it is a tradeoff between performance and security. This project is for anyone who runs a web server or manages network services and needs to set up secure connections. For example, if you are launching an e-commerce site and need to protect customer data, or managing internal tools where traffic disclosure would be a serious problem, these configurations give you a solid, informed baseline. It is especially useful for people who cannot afford to follow every piece of cryptography news but still want strong, up-to-date settings. What is notable about the project is how it handles the reality that no single configuration works everywhere. Different server software and different versions of encryption libraries support different ciphers, so the same setting string can produce entirely different results depending on your setup. The README acknowledges this complexity and frames its files as informed recommendations rather than universal solutions. It also highlights a practical tension: if you enforce only the strongest encryption, some users with older browsers or devices will be silently locked out with no explanation.
