Problems of r and rPrime generation in getDividedShares() function

[dujifeng]

In your code, you just set r = 0 and rPrime = 0, which is unsecure. Can you tell me how to generate r and rPrime correctly?

The codebase doesn't implement the pre-processing. While there may be different ways to generate the preprocessing, one specific way is described in the section on Share Truncation 2 in ABY3 (page 14).
