Re: [MirageOS-devel] Compiling C components for mirage-xen

[Arnaud Sahuguet <arnaud.sahuguet@xxxxxxxxxxx>]

Naive question: for low-level primitives like crypto that require speed, when do you/we prefer native implementation (in C at the libOS level) vs oCaml implementation?

I wonder whether it'd be more than a day of work to implement bcrypt
directly in OCaml. Would for sure safe from linking trouble (and be
automatically memory safe). An initial version might be 50% or 90% of
the speed of the pure C variant, but does this really matter for bcrypt?
