Python port of Shamir key Split and Combine methods from Hashicorp Vault.
pip install pyshamir from pyshamir import split, combine
import secrets
# generate a random secret, here secret is a 32 bytes
secret = secrets.token_bytes(32)
# set the number of shares; i.e. the number of parts to split the secret into
num_of_shares = 5
# threshold is minimum number of keys required to get back the secret
threshold = 3
# split to get a list of bytearrays which can be combined later to get back the secret
parts = split(secret, num_of_shares, threshold)
# Now, the parts be combined to get back the secret
recomb_secret = combine(parts)
