The official Steem Python library: https://github.com/steemit/steem-python seems no longer under maintenance.
From Python3.8.14 changes logs: https://docs.python.org/3.8/whatsnew/changelog.html
it says:
gh-95778: Converting between int and str in bases other than 2 (binary), 4, 8 (octal), 16 (hexadecimal), or 32 such as base 10 (decimal) now raises a ValueError if the number of digits in string form is above a limit to avoid potential denial of service attacks due to the algorithmic complexity. This is a mitigation for CVE-2020-10735.
I created a new VPS, ubuntu 22.04, and it comes with Python 3.10.4. I was running the following Python script to claim steem rewards:
def claim(user, key):
global steem_nodes
wif = {
"posting": key
}
try:
steem = Steem(nodes=steem_nodes,keys=wif)
account = Account(user, steemd_instance=steem)
sbd = account.balances["rewards"]["SBD"]
st = account.balances["rewards"]["STEEM"]
vests = account.balances["rewards"]["VESTS"]
if sbd > 0 or st > 0 or vests > 0:
print('claiming rewards for ' + user + " ...")
steem.claim_reward_balance(account=user)
else:
print('nothing to claim for ' + user)
except Exception as e:
print("Unexpected error for " + user, sys.exc_info()[0])
print(e)
And it says:
class 'ValueError': unsupported hash type ripemd160
Google leads to this SO page: https://stackoverflow.com/questions/72409563/unsupported-hash-type-ripemd160-with-hashlib-in-python
And it works!
Great catch!
