Quoted... and verified using Electrum.

Doesn't quite verify exactly on brainwalletx as your formatting is incorrect... it SHOULD be:

Code:

-----BEGIN BITCOIN SIGNED MESSAGE-----
This address belongs to cpoer2011 (uuid 377005) from bitcointalk.org, today is 2018/05/25
-----BEGIN SIGNATURE-----

-----END BITCOIN SIGNED MESSAGE-----

Which will verify using brainwalletx

Thank you so much for answering. I have this issue now. Those problems I think are fixed, I have a doubt, what is the "wallet passphrase I should put there to create the signature?

When you created that wallet in Bitcoin Core, you have opted to "encrypt" the wallet file and created a wallet passphrase... It's a password that should only be known to you and is not recoverable or resettable.

If you do not know what this password is, you will be unable to execute any commands that require access to the private keys stored in the wallet (ie. Importing private keys, exporting private keys, creating transactions, signing messages)

If you have any coins in that wallet... And you don't know the passphrase, you will most likely be unable to recover those coins.

I still don´t know how to get my private key of the addresses generated from B.info.

B.info only allows you to export private keys that were manually imported to b.info

To access private keys for addresses generated by their HD wallet, you would need to use Ian Coleman's mnemonic tool (https://iancoleman.io/bip39/). You enter you 12 word recovery phrase at the top, select BIP44 and you should see your addresses and matching private keys shown at the bottom of the page.

NOTE: You should NOT enter your seed into a website unless you fully understand the implications of doing so.

It is recommended to download the website and run it offline. You should also consider the wallet compromised and move any coins to a new wallet to prevent loss of funds etc.

Also, if you don't see your b.info addresses, try clicking the BIP32 tab and then selecting "blockchain.info" from the "client" drop-down box.

What wallet do you recommend me to do that?
And could you put those solutions here please?

I didn't do it yet, you should go to the first message of this thread which explains how you shoud do. You could try with electrum for example.

Hi, this is normal?

I clicked on "Sign Message" to create the signature but it cannot. Sad

The key was generate from B.info

I´ve tried to create a signature but I don´t achieve it. Please help me.

Did you actually import the Private Key from blockchain.info into Bitcoin Core using the importprivkey command? Or did you just import the "Address"? The error you are getting indicates that you have no imported the private key into your wallet.

Or when I generate a new address from the software (Bitcoin Core) it appears like this:

Your Bitcoin Core is generating "SegWit" P2SH-P2WPKH addresses (they start with a "3")... Currently, there is no standard method for signing a message using these addresses. You need to generate a "legacy" P2PKH address in Bitcoin Core (starts with a "1")... Then you will be able to sign a message with the "1" address.

To make Bitcoin Core create "1"-type addresses, you need to either start it with the commandline argument -addresstype=legacy or use the following command in the debug console:

Code:

getnewaddress "" "legacy"

I still don´t know how to get my private key of the addresses generated from B.info.

Hi

I'm sorry but it's not possible to sign a message with the update of blockchain.info.

https://bitcointalksearch.org/topic/how-to-make-a-signature-message-on-blockchaininfo-1428491

Support team answered : "the sign message feature is not available in the new wallet"

You'll have to look for another solution (there are many others)

What wallet do you recommend me to do that?

Thank you very much for this post which is ultra important with all the hacks and account thefts that there are on the forum. However, some methods are no longer up to date... Is it possible to update the approaches for the most used wallets? I can't sign a message: /

I helped to recently add most used hardware wallets: Ledger Nano S & Trezor.
Can you please tell us which wallet you want to use? It will be easier to help you.

Anyone have recomendation for address easy to work, then have to sign a message?

I have no clue how to decipher what you said.
Assuming that you have a bitcoin address in a wallet that allows you to sign messeges (example : Bitcoin core or electrum...), you should follow the tutorial made here by shorena. Put your address, add a personalised message (example : today is April 8, 2018, my name is X (id=xx) from bitcointalk.org) then the wallet will give you a signature that others could verify it.
Remember never reveal your private address to anyone. All you have to do is to post here your Bitcoin address (usually starts with 1xxxx...), your message and the signature provided by the wallet.
