Created using the old code:
from allmydata.util.keyutil import make_keypair, parse_privkey, parse_pubkey
test_data = b'test'
priv_str, pub_str = make_keypair()
priv, _ = parse_privkey(priv_str)
pub = parse_pubkey(pub_str)
sig = priv.sign(test_data)
pub.verify(sig, test_data)
This simply checks that keys and signatures generated using the old code are still valid
using the new code.
