About Guile crypto support

[Nala Ginrut]

As mentioned in another thread about digest algorithm support in Guile,
my plan is use part of implementation of libgcrypt and make a wrapper,
then put into libguile.
But now I found weinholt's Scheme industria lib, which contains all
mainstream crypto(not only digest) algorithm.

So what's your opinion, guys?
Would you prefer C implementation or Scheme way?

Thanks!
