Bug found in SUM constructor when it's called with more than 1 algorithm

[Buzzeitor30]

Text description

Constructor of the SUM class doesn't initialize correctly when there is present more than 1 algorithm in the arguments to calculate hashes

Actual behavior

If you create an object with more than one algorithm as an argument and then call calculate() it won't take into account the first algorithm of the list passed as argument to the constructor

Expected behavior

It should calculate all the algorithms asked

Steps to reproduce the behavior:

Create a Python file and import sum.py, then create a SUM object and pass a list of all the algorithms without repeating any of them. Finally, call calculate() to see the result

Fix

Check the constructor line

        if len(self.config.algorithms) > 1:
            self.config.algorithms = list(set(self.config.algorithms[1:]))

and replace

    self.config.algorithms = list(set(self.config.algorithms[1:]))

with

    self.config.algorithms = list(set(self.config.algorithms[0:]))
