5f657fda2e Remove powF2m' 
We keep only the function providing the base service, negative
exponents can be still computed with invF2m.

3c41966b9a Add module Crypto.Number.Nat 
This new module exposes type constraints required by some hash
algorithms and provides functions to check whether the constraints are
satisfied with runtime values.

Resolves #256.

133c6e1b2d Added some redundant constraints for documentation/consistency. Added an INLINABLE pragma to i2ospOf to hopefully increase specializations. 2019-02-24 17:04:10 -08:00

0cec622ddf Fix generate(Safe)Prime to guarantee prime size 
Add check for size in generatePrime

Add size test in generateSafePrime

Require only that top bit is set, instead of top 2

This is the general standard, see e.g. OpenSSL

Add an error for too few bits being supplied to prime generator, and add documentation

Add some documentation and require highest two bits set

Simplify return syntax in generatePrime and generateSafePrime

Switch exponent to bit-shift for small performance boost
