Right now, eCryptfs just delegates its modular exponentiation
operations to a userspace daemon. If RSA ever finds its way into the
kernel, I might tweak eCryptfs to use that instead for some of the
public key operations.

Am I right in thinking that RSA uses many of the same MPI lib bits
as DSA?

I would imagine so. Assuming we aren't having to hassle with key
generation (eCryptfs takes care of that in userspace), then RSA is,
more or less, a^b mod c (mpi_mulpowm() and friends).
