SecretUtil object has no attribute 'verbose'

[andreaferretti]

It appears that SecretUtil tries to access a variable member verbose, which is never set, causing a failure during SecretUtil.recoverSecret(). Here is an example that will trigger the failure

from charm.toolbox.pairinggroup import PairingGroup
from charm.toolbox.secretutil import SecretUtil

pairing_group = PairingGroup('BN254')
secret_util = SecretUtil(pairing_group)
policy = secret_util.createPolicy('a and (b or c)')
shares = secret_util.calculateSharesDict(15, policy)
secret_util.recoverSecret(shares)

This results in

AttributeError                            Traceback (most recent call last)
<ipython-input-1-a10aff91f822> in <module>
      6 policy = secret_util.createPolicy('a and (b or c)')
      7 shares = secret_util.calculateSharesDict(15, policy)
----> 8 secret_util.recoverSecret(shares)

     48         if user indeed has at least k of n shares, then secret will be recovered."""
     49         list = shares.keys()
---> 50         if self.verbose: print(list)
     51         coeff = self.recoverCoefficients(list)
     52         secret = 0

No, sorry
