Title: How to import many priv keys in one query Post by: ArthurY on June 13, 2022, 10:58:32 AM Could you help me guys to show me up an example of RPC call how to import many priv keys in a single query
As I understood I should use `importmulti` request. But I do not know which kind of script, address etc should place if I just need to import bulk of keys For example which request should I run to import such of keys? 5Jza3odChZ1vfzmRSSK6qJZCuGdXYR4RndFHXx1KEWq9AiDkwCj 5JebES9429R4HNFUcX5kFgR7FAoFWxpHZ3XrvAf4bSNNxijzxRB 5J4WYCjKqG7JxY3fjj2ukusd36mXMVas42bTh2nesd6HwaFtwh7 Title: Re: How to import many priv keys in one query Post by: BlackHatCoiner on June 13, 2022, 12:43:24 PM As I understood I should use `importmulti` request. But I do not know which kind of script, address etc should place if I just need to import bulk of keys If your private keys start with "5", it means their public key is uncompressed. So, it's P2PKH. So make sure your wallet is not descriptor. For example which request should I run to import such of keys? Why don't you loop importprivkey (https://developer.bitcoin.org/reference/rpc/importprivkey.html)?Code: bitcoin-cli importprivkey "private_key" "label" false With RPC, it'd be: Code: curl -u USERNAME:PASSWORD --data-binary '{"jsonrpc": "1.0", "id": "curltest", "method": "importprivkey", "params": ["PRIVATE_KEY", "label_x", false]}' -H 'content-type: text/plain;' http://127.0.0.1:8332/wallet/WALLET_NAMECreate a txt file and insert your private keys there like: Code: ("foo.txt") 5Jza3odChZ1vfzmRSSK6qJZCuGdXYR4RndFHXx1KEWq9AiDkwCj Now create this bash script. It reads every line of your text file and runs the curl command. Code: ("test.sh") #!/bin/bash Replace USERNAME, PASSWORD and WALLET_NAME accordingly. On linux you can run it with: Code: bash test.sh I'd make sure I connect to my Bitcoin server via a secure transfer protocol, because there's sensitive info transferred.

Code: for i in `seq 1 3`; for: Code: for i in $(cat foo.txt); or another solution is to change the 3 for a variable: Code: z=$(cat foo.txt | wc -l) This way the script will work for any number of Private keys in the file.

Since this executes the RPC server for each private key though, it's going to slow down once you reach a hundred PKs or so, especially if your node is somewhere far away n the public internet (then latency also has to be considered). Quote I'd make sure I connect to my Bitcoin server via a secure transfer protocol, because there's sensitive info transferred. The only option would be calling it via an .onion address on Tor, since even the RPC password is sent unencrypted. It is indeed unsafe to issue any RPC call with plain HTTP because of the unencrypted password.
