no "util", "misc", or similar uncategorized namespaces in the standard library

In particular this would mean that std.crypto.utils.secureZero would be rename to std.crypto.secureZero.

Go and Javascript put that kind of functions in a subtle namespace, which I never found very self-explanatory.

To keep some namespacing, would it be acceptable to have std.crypto.mem even though we already have std.mem?

subtle is used inconsistently and doesn't describe at all what the namespace contains. It's even worse than utils.
We can do better.

Many C++ libraries like Boost and Eigen use detail or internal as sub-namespaces to encapsulate internal helper functions. Perhaps conventionalizing on using one of those to organize internal logic would make things cleaner and easier to find?

I'm fine with that but why not std.crypto.secureZero ?
