MMoSP003C- steem-python 定制修改密码的工具

一般我们从官网 steemit.com 注册账号,相对比较安全.

密码丢失后(被盗后),可以找 steemit.com 帮助恢复.

当然,能被恢复,就意味着被其他人更改.但steem机制时,如果上一次密码不能提供,则无法恢复.

因此,不管我们的账号是从哪儿获得,连续改两次密码,并保留两次更改的密码,则只能有自己能够恢复密码了,其他人就不能恢复密码.

我们一般登陆 steemit.com,在官方在线钱包中 修改密码,但就比较麻烦,不如直接命令行用工具改.

这里就示范一个修改密码的工具(MMoSP003_customize_a_tools_for_change_keys.py):

# 修改 steem 帐号密码
# python MMoSP003_customize_a_tools_for_change_keys acc wif
# acc:steem账户名
# wif:steem账户名旧的 owner private key

# 必须参数
try:
    acc = sys.argv[1]
    wif = sys.argv[2]

    'https://api.steemit.com'

stm = Steemd(nodes=steemd_api_nodes)
set_shared_steemd_instance(stm)

# 生成一套新密码
bk = BrainKey()
brainkey = bk.get_brainkey()
print('brain key:', str(brainkey))
prikey = str(bk.get_private())
print('private key:', str(prikey))
pubkey = format(bk.get_public(), "STM")
print('public key:', str(pubkey))

# 获取整套密钥
posting_key = PasswordKey(acc, pubkey, role="posting")
active_key = PasswordKey(acc, pubkey, role="active")
memo_key = PasswordKey(acc, pubkey, role="memo")
owner_key = PasswordKey(acc, pubkey, role="owner")
# 提取整套密钥中的私钥

memo_pubkey = memo_key.get_public_key()
print('memo_pubkey:', str(memo_pubkey))

try:

    client = steem.Steem(nodes=steemd_api_nodes, keys=[old_owner_key])
    #client = steem.Steem(nodes=['https://testnet.steem.vc'], keys=[wif])

    new_pubkey = {}
    for role in ["owner", "active", "posting", "memo"]:
        private_key = PasswordKey(
            acc, pubkey, role).get_private_key()
        new_pubkey[role] = str(private_key.pubkey)

    new_data = {
        "account": acc,
        "json_metadata": {},
        "owner": {
            "key_auths": [

            ],
            "account_auths": [],

        },
        "memo_key": new_pubkey["memo"]
    }
    print("New data:", new_data)

    op = operations.AccountUpdate(**new_data)
    result = client.commit.finalizeOp(op, acc, "owner")
    print("Result:", result)
except Exception as err:
    print(acc, " err:", err)
