Usage of Botan v3.x along with project implemented with c++14 #3631

Would be any problems popped up for me during inclusion header of botan or usage of this library along with project has a constraint of usage only C++14 ? |

GCC 12 should be enough to build Botan 3.x. Nevertheless, the library uses C++20 features (eg. Anyway, as long as you don't require new features added in Botan 3.x, you could stay on Botan 2.x that is a C++11 code base. Support and security fixes -- if necessary -- will be available until at least the end of next year. |

Unfortunately, I need to work with TLS v1.3 which is a feature of botan 3.x. |

You are right. TLS 1.3 is neither part of Botan 2 nor is it currently exposed via the C bindings. Adding it to the bindings would certainly be a nice improvement. Though, I don't have capacity for it right now. Maybe you could extract the TLS functionality into a small library that is compiled using C++20 but exposes a C++14-compatible interface. What's the TCP networking stack you're planning to use? |

Regard to your question: I am planing to integrate TLS with SomeIP so that I could secure communication across transport layer. However, you suggest that the only solution I could do so that I could work with botan 3.x is to extract functionality I want to use into an external library and build its own c++14 interface. I am getting you, right ?! Thank you for your quick reply BTW <3 |

That's what I mean, yes. Basically write a wrapper around Botan's APIs that expose the functionality you need via an interface that uses C++14 exclusively. You'll need to compile this wrapper using C++20, but you should be okay to include and use your wrapper's header files in a C++14 project. Disclaimer: Personally I haven't been in a situation that required such an approach. But I don't see why this wouldn't work. Another option, of course, would be to compile your project in C++20 mode. If you use GCC 12 that should be possible. But most likely you have good reasons not to do that. 😉 |

std::spanand concepts) in the public headers. If your code base is restricted to C++14 that will likely be a problem, as long as you don't want to wrap things into your own interface or use Botan's C-Bindings.Anyway, as long as you don't require new features added in Botan 3.x, you could stay on Botan 2.x that is a C++11 code base.
