I face the same issue. I tried to abort and I get this:
in secret_int_to_points coefficients = random_polynomial(point_threshold-1, secret_int, prime) File "/usr/local/lib/python2.7/dist-packages/secretsharing/polynomials.py", line 34, in random_polynomial random_coeff = randint(0, upper_bound-1) File "/usr/local/lib/python2.7/dist-packages/secretsharing/entropy.py", line 41, in randint byte_from_entropy = get_entropy(numbytes_of_entropy) File "/usr/local/lib/python2.7/dist-packages/secretsharing/entropy.py", line 23, in get_entropy return dev_random_entropy(numbytes) File "/usr/local/lib/python2.7/dist-packages/secretsharing/entropy.py", line 14, in dev_random_entropy return open("/dev/random", "rb").read(numbytes)
Hey @UrsaEli @Elfrania the reason for this is it is using /dev/random (which blocks if there's not enough entropy in the entropy pool) instead of /dev/urandom (which doesn't block). I'm going to change it to use the latter and then I'll let you know.
There was a controversy in the crypto community in the past over which was better, but it's become pretty clear that /dev/urandom uses a better model. I'll make this fix and we'll get you up and running in no time.
Actually this shouldn't be happening. @Elfrania I believe you might have an older version of this library. Can you let me know what the version number is? And if you do pip install secretsharing --upgrade
is the problem fixed?
Same issue:
I just run this. The first time it may work, but if I run it a few times, it will hang.
from secretsharing import SecretSharer
total_number_of_shares = 3; shares = SecretSharer.split_secret("c4bbcb1fbec99d65bf59d85c8cb62ee2db963f0fe106f483d9afa73bd4e39a8a", 2, total_number_of_shares);
print len(shares); # total_number_of_shares print "Splitting into shares: ", shares;
I retested the code, it's slow but it's completing now.
Thank you, Ryan.
@Elfrania can you please type pip freeze
in your command line and then let me know what the version number is for your copy of the secretsharing
library?
Thanks!
secretsharing==0.2.6
Hi Ryan, I ran the examples, it seems to hang at the entropy part.
Thank you.
