-
vector
An efficient implementation of Int-indexed arrays (both mutable and immutable), with a powerful loop optimisation framework . -

hgeometry
HGeometry is a library for computing with geometric objects in Haskell. It defines basic geometric types and primitives, and it implements some geometric data structures and algorithms. The main two focusses are: (1) Strong type safety, and (2) implementations of geometric algorithms and data structures that have good asymptotic running time guarantees. -
-
dimensional
Dimensional library variant built on Data Kinds, Closed Type Families, TypeNats (GHC 7.8+). -

-
numhask
A haskell numeric prelude, providing a clean structure for numbers and operations that combine them. -
-
-
poly
Fast polynomial arithmetic in Haskell (dense and sparse, univariate and multivariate, usual and Laurent) -
-
-
eigen
Haskel binding for Eigen library. Eigen is a C++ template library for linear algebra: matrices, vectors, numerical solvers, and related algorithms.

HsPaillier
A implenmentation of Paillier cryptosystem
The Paillier cryptosystem has some homomorphic properties.
- Homomorphic addition of plaintexts
- Homomorphic multiplication of plaintexts
Those properties mean that you can manipulate the ciphertext without decrypting it first.
For example,
(pubKey, prvKey) <- P.genKey 256
let p = 2 :: Integer
c <- P.encrypt pubKey p
let p' = 100 :: Integer
c' <- P.encrypt pubKey p'
let c'' = P.cipherMul pubKey c c'
putStrLn $ "plaintext: " ++ show (P.decrypt prvKey pubKey c'')
The result will be 102 which is 2+100 (We just decrypt once!)
The above example is in the Main.hs
