The current documentation for scrypt password hasher lacks some
constraints and definitions:
1. work_factor: described incompletely, missing the requirement that
this value must be a power of 2
2. block_size: has no description
3. parallelism: needs to be defined, perhaps, as "independent
computations" rather than "threads", because the current OpenSSL
implementation is not multithreaded.
If OpenSSL becomes multithreaded, the "Estimating memory usage" note also
needs to be adjusted to account for parallelism.
I think it would also be helpful to mention that these parameters are N,
r, p, as these are standard terminology for those familiar with scrypt.
I'll send a pull request shortly.
