This guide explains Bitcoin Core signrawtransactionwithkey RPC in plain English. It shows what the command does, what its result means and what it cannot prove.
TL;DR
- What it is: Bitcoin Core 0.17.0 signrawtransactionwithkey accepted transaction hex and a required array of base58 private keys, which were the only keys used. Optional previous-output records supplied txid, vout, scriptPubKey, redeem script and amount; sighash defaulted ALL.
- Why it matters: signrawtransactionwithkey exposes full keys for narrow signing. Safe operation isolates secrets, authenticates previous outputs and refuses anything short of a complete, re-decoded result.
- Current position: Require a second reviewer and explicit rollback or expiry, and pause payments, signing or network-dependent services until post-change evidence is complete.
Bitcoin Core signrawtransactionwithkey RPC in simple English
Bitcoin Core signrawtransactionwithkey RPC: Minimise the required WIF array and use an isolated signer. Prevent shell history, logs, swap and crash dumps retaining secrets.
Simple example
A miner is checking Bitcoin Core signrawtransactionwithkey RPC. Review every input, output, amount, sequence and locktime before supplying a key. Prevent shell history, logs, swap and crash dumps retaining secrets.
Key terms in plain English
- Bitcoin Core:
- Widely used software that validates Bitcoin and can provide wallet, network and operator tools.
- RPC:
- A command that software sends to a node to request information or a local action.
- PSBT:
- A portable format for passing an unsigned or partly signed Bitcoin transaction between tools and signers.
- Node:
- A computer running Bitcoin software that checks data and communicates with other peers.
Decode first
Review every input, output, amount, sequence and locktime before supplying a key. Bind a hash of approved unsigned intent to the request.
Only supplied keys
Minimise the required WIF array and use an isolated signer. Prevent shell history, logs, swap and crash dumps retaining secrets; prefer PSBT or hardware workflows.
Previous outputs
Authenticate txid, vout, scriptPubKey, amount and redeem script. Incorrect witness amount is dangerous and must fail rather than be guessed.
Sighash
ALL is default. NONE, SINGLE and ANYONECANPAY variants change commitments. Require specialist approval and display what remains mutable.
Complete and errors
Require complete true and inspect every input error. Non-empty hex can be partial and must never reach broadcast automation.
Cleanup
Decode again, compare intent and fee, then erase transient keys. Record redacted identifiers and hashes, never WIF or secret-bearing requests.
How specialists test it
Operators test the command on a non-production node first. They check a normal reply, an invalid request, a timeout and a restart. This shows what the response means and prevents one local result from being mistaken for a network-wide outcome.
