Help needed for SecFld array conversion

[abraj]

Hi,
Is there a way to convert a list of SecFld1(GF(2) objects to a single ArraySecFld1(GF(2)) object
without revealing the values.

from mpyc.runtime import mpc
import numpy as np

secfld = mpc.SecFld(2)

arr1 = np.array([secfld(1), secfld(2), secfld(3)])
arr2 = secfld.array(np.array([1, 2, 3]))

print(arr1)
# [<mpyc.sectypes.SecFld1(GF(2)) object at 0x103a13670>
#  <mpyc.sectypes.SecFld1(GF(2)) object at 0x1066e11e0>
#  <mpyc.sectypes.SecFld1(GF(2)) object at 0x1066e0040>]

print(arr2)
# <mpyc.sectypes.ArraySecFld1(GF(2)) object at 0x1066e1120>

I am trying to use the SHA3 hashing approach where an intermediate function only works with
the input as ArraySecFld1(GF(2)) object and it does not work when the provided argument
is a list of SecFld1(GF(2) objects.

I believe mpc.np_fromlist and mpc.np_tolist can be used for this.
So, closing the discussion.
