Implementation of symmetric order-preserving encryption scheme

This is an implementation of Boldyreva symmetric order-preserving encryption scheme (http://www.cc.gatech.edu/~aboldyre/papers/bclo.pdf).

Quick example

from pyope.ope import OPE
cipher = OPE('key goes here')
assert cipher.encrypt(1000) < cipher.encrypt(2000) < cipher.encrypt(3000)
assert cipher.decrypt(cipher.encrypt(1337)) == 1337

TODO

• More tests

• Nice README

• Get rid of numpy dependency (rewrite hypergeometric sampling code?)

• Optimize speed

• PyPi package

• Security guarantees
