I can successfully do a getbalance RPC with digest authentication, e.g.:

url = "http://localhost:18082/json_rpc"
headers = {'content-type': 'application/json'}
rpc_input = {
       "method": "getbalance"
}
rpc_input.update({"jsonrpc": "2.0", "id": "0"})
response = requests.post(
    url,
    data=json.dumps(rpc_input),
    headers=headers,
    auth=HTTPDigestAuth('wallet_username', 'wallet_password'))
print(response.text)

However, when I want to do a create_wallet RPC I get an Unauthorized Access HTML response:

<html><head><title>Unauthorized Access</title></head><body><h1>401 Unauthorized</h1></body></html>

E.g.:

url = "http://localhost:18082/json_rpc"
headers = {'content-type': 'application/json'}
rpc_input = {
        "method": "create_wallet",
        "params": {"filename": "mytestwallet", "password": "mytestpassword", "language": "English"}
}
rpc_input.update({"jsonrpc": "2.0", "id": "0"})
response = requests.post(
    url,
    data=json.dumps(rpc_input),
    headers=headers,
    )
print(response.text)

I do notice that the create_wallet RPC does not take a wallet username parameter, could this be my problem, or am I missing something else? (Note that at https://getmonero.org/resources/developer-guides/wallet-rpc.html#create_wallet the example does include a filename parameter but no username parameter).

  • In your second request the method is "create wallet" instead of "create_wallet", and the "auth=HTTPDigestAuth('wallet_username', 'wallet_password'))" line is missing. Are these typos or actual mistakes in your code? – glv Oct 12 '17 at 8:18
  • @glv I was actually using create_wallet and not create wallet without the underscore as per the docs (getmonero.org/resources/developer-guides/…) - I have fixed this in my question. When I run this second part (with create_wallet) and the wallet with --disable-rpc-login then the wallet creation succeeds. So I guess my question really becomes, how do I authenticate with HTTPDigestAuth when I don't yet have a wallet_username or wallet_password? I mean, I am creating the wallet with create_wallet, so it wouldn't have these credentials yet. – user8615908 Oct 12 '17 at 10:55

When digest authentication is activated in the monero-wallet-rpc program (with the rpc-login option), every RPC request must contain the authentication information.

So your request should be something like:

url = "http://localhost:18082/json_rpc"
headers = {'content-type': 'application/json'}
rpc_input = {
        "method": "create_wallet",
        "params": {"filename": "wallet_file", "password": "wallet_password", "language": "English"}
}
rpc_input.update({"jsonrpc": "2.0", "id": "0"})
response = requests.post(
    url,
    data=json.dumps(rpc_input),
    headers=headers,
    auth=HTTPDigestAuth('rpc_username', 'rpc_password'))
print(response.text)

There is no relation between the name and password required to connect to the RPC server of the monero-wallet-rpc program and the name and password of the wallet file.

They should be different, so that if someone gets to know the credentials of the RPC server (e.g. by reading your configuration file for monero-wallet-rpc or by listing the processes running on your machine and seeing what parameters were passed to the --rpc-login option), your wallet file is not compromised.
