Comparing OpenSSL with Botan

Most TLS libraries are written in C and provide their main API in C. Botan is a TLS library written in C++11 that adopted C++17 in version 3.0. Botan provides its main API in C++ but also provides API bindings for C and Python. Third-party projects provide API bindings for Ruby, Rust, and Haskell. There are also experimental API bindings for Java and Ocaml.

It’s also worth mentioning that the Botan library has good documentation. Botan is distributed under a simple two-clause BSD license, which allows users to use the library in both open source and closed source applications.

I recommend Botan for developers who want to use the C++ API and are willing to accept a less popular library with a smaller developer community. If you want to use the C API or want a more performant library with a larger developer community, then stick with OpenSSL.

The Botan library has a larger footprint on your storage than OpenSSL, unlike lightweight TLS libraries, which we will discuss next.
