Verify user public key by signing raw transaction with private key

Verify user public key by signing raw transaction with private key

I have to verify that user who enters public key of his address verify his address by signing a neutral raw transaction which won't be broadcasted. Don't know which transaction to use to create a new raw transaction.

I have tried to make send to same address in order to make transaction that will be input for raw transaction but I got 16: mandatory-script-verify-flag-failed (Script evaluated without error but finished with a false/empty top stack element) when I tried to send that transaction.

bitcoin node: what is the difference between simnet and regtest?

bitcoin node: what is the difference between simnet and regtest? btcd, and presumably other bitcoin node implementations, seem to have 4 network options: mainnet testnet regtest simnet. I get that mainnet and testnet both are "public" in that your node will communicate with other nodes and that both have an existing blockchain and genesis block. However, from what I can tell, both simenet and regtest both create a local only blockchain, and both will create a new genesis block. I this case, what is the difference, and which is better (easier) for developing bitcoin applications? This is what the documentation has to say: --regtest Use the regression test network --simnet Use the simulation test network https://ift.tt/2TAMkwe

Need help to recover blpckchain.info wallet, my wife forgot her password and the brute force with btcrecover is not catching the password

Need help to recover blpckchain.info wallet, my wife forgot her password and the brute force with btcrecover is not catching the password I used btcrecover to extract the wallet file (wallet.aes.json) from a blockchain account and I have been running btcrecover with dictionaries of my making but it has been going on for weeks and I am running out of ideas on how to permutate what my wife and I think the password could have been. Is there a way to just manually transfer the btc from the old wallet into a new wallet we do have access to or is there any way to extract the password or private keys directly from the wallet file? We have: the phone with the original wallet app installed, the wallet file pulled using btcrecover, access to the email to allow authorization to access, the wallet identifier that was sent to her email when she first signed up, the phone which has the wallet, the pin that was used for the wallet, and we know how much btc is in the account. We do not have: The pri...
