 This will make it easier to maintain, as well as easier to create
 new/alternate implementations of portions of the code (e.g. in Rust).
 `crypto.h` is already somewhat neatly partitioned into sections. nickm

 > something like: rsa, stream cipher, digest+xof, prime-field dh, openssl
 management, PRNG, and derived functions.
