Unless something has changed recently, Botan, Crypto++ and OpenSSL are
still being carried by most Linux distributions. OpenSSL is also
regularly distributed as part of other OSes, like AIX, Android, BSDs,
iOS, OS X and Solaris.
And unlike some other projects,[1] Botan, Crypto++ and OpenSSL
actually work in practice on all the platforms without a configuration
program that performs feature tests.
[1] the Rust compiler comes to mind here. It works on Linux x86_64,
but it's hit or miss whether it works or not on other architectures
like ARMv7, Aarch64 and PowerPC, even after an approved configuration
program is run.
