"""A Python 3 script to write a file with a specified number
|
|
of keypairs, using bigchaindb.common.crypto.generate_key_pair()
|
|
The written file is always named keypairs.py and it should be
|
|
interpreted as a Python 2 script.
|
|
|
|
Usage:
|
|
$ python3 write_keypairs_file.py num_pairs
|
|
|
|
Using the list in other Python scripts:
|
|
# in a Python 2 script:
|
|
from keypairs import keypairs_list
|
|
# keypairs_list is a list of (sk, pk) tuples
|
|
# sk = private key
|
|
# pk = public key
