Setup

Download the files from: https://pypi.org/project/mpyc/#files

    conda create --name mpc
    conda activate mpc
    conda install gmpy2
    conda install numpy pandas matplotlib
    conda install -c conda-forge lifelines
    conda list scikit-learn
    conda install -c anaconda scikit-learn
    conda install -c anaconda requests
    cd mpyc-0.7
    python setup.py install
    cd ..

    # add the following to the python env
    pip install nest-asyncio

Sanity

    Python

    >>> from mpyc.runtime import mpc
    >>> secint = mpc.SecInt()
    >>> secint.bit_length
    32 # the bit length of the secret integer


    >>> x = secint(3)
    >>> y = secint(5)
    # x and y are secret integers
    >>> x
    >>> y
    >>> mpc.output(x)
    >>> z = mpc.output(x * y)
    >>> z
    # at this point z is a coroutine object, 
    # which means that we were greedily and we've returned immediately, 
    # but nothing happened because we did not run this z coroutine object yet
    >>> mpc.run(z)
    >>> mpc.run(mpc.output(x+y))

    >>> x = mpc.random_bit(secint)
    >>> print(mpc.run(mpc.output(x)))
    0
    >>> x = mpc.random_bit(secint)
    >>> print(mpc.run(mpc.output(x)))
    1

Passwords

"e&t.C_^q2RFrP%" --> url encoding: e%26t.C_%5Eq2RFrP%25
"+C%pzA9tM8zJ3r" --> url encoding: %2BC%25pzA9tM8zJ3r

CLI

python password.py "e&t.C_^q2RFrP%"

python password.py "+C%pzA9tM8zJ3r"

Invoke the lambda function directly (data parameters in event.json file):

            sam local invoke "LoginFunction" -e events/event.json

Local server

Launch one Terminal:

            sam local start-api

In a second Terminal, run:
