import libcx

# Construct a Preseed Value and Preseed Key Pair
preseed = libcx.Preseed.value(libcx.CX_GEN_AES_128_CTR_2048)
key = libcx.Preseed.key()

# Construct a Seed Calculator
seedcalc = libcx.SeedCalculator(libcx.CX_GEN_AES_128_CTR_2048, preseed, key)

# Construct a Generator
gen = seedcalc.generator

# Construct a list of Contact Identifiers
ids = list(gen)
