[Haskell] ANNOUNCE: hecc-0.2

[Marcel Fourné]

Hi again,
this is the second release of hecc, the Elliptic Curve
Cryptography Library for Haskell, to be found at

http://hackage.haskell.org/package/hecc

There are only some smaller changes since the first release **3...

* license change to the more common BSD3
* proper benchmarking
* speed improvements
* timing-attack resistant default point multiplication
* simple key generation (given a generator on the curve used)

En Detail: There are now 2 algorithms for point multiplication, the
classic double-and-add (dnadd) and a montgomery ladder(montgladder).
Dnadd varies in speed between 200us (degenerate case: long rows of
zeroes) and 4.6ms while montgomery ladder (almost, see **1) always takes
its 4.6ms. **2 

Notes: 
**1 except when multiplying by binary numbers with trailing long rows of
zeroes (e.g. 2^254), in which case it also takes 200us (cache?...
anybody got more ideas how to fix this?)
**2 Test HW: 2.4Ghz Core2, accompanying src/bench.hs, projective
coordinates used
**3 (due to an annoyingly complicated fracture of my main hand)

This library still uses plain Haskell, in case anybody wants to
ask... ;-)

Still considered alpha, so beware of dragons!

Almost enjoying holidays, welcoming feedback,
Marcel

A good library is preferable to a tool, except when you just need that
one tool.
