# for secret in ['alice', 'bob', 'eve']:

#     pubkey = crypto.privtopub(privkey)
#     print("    privkey='{}',".format(encode_hex(privkey)))
#     print("    pubkey='{}',".format(encode_hex(crypto.privtopub(privkey))))
#     ecc = crypto.ECCx(raw_privkey=privkey)
#     sig = ecc.sign(msghash)
#     print("    sig='{}',".format(encode_hex(sig)))
#     print("    raw_sig='{}')".format(crypto._decode_sig(sig)))
