Blockchain signing message

[termin83r]

Hi, when I sign a message and then try to verify it, it says message is invalid or something like that.

I follow all the steps, and do the same steps from before (it worked before) but today its not working.....

What wallet you used for sign message? Are you sure about your private key?
Verify your message here: https://brainwallet.org/

^^^review that thread for instructions as to how to sign/verify a message with blockchain.info

If you have the address in your wallet then you will defiantly be able to verify a message that you sign provided that you copy the address, message and signature exactly.

I use blockchain.

I even tried to create a new blockchain and test it there, I made a signature, used brainwallet to verify it and it was not able to verify.

I made sure there were no extra symbols or spaces but it still says invalid :/

ofcourse he is talking about blockchain.info/wallet, I am sure he's not asking how to sign a message with bitcoin blockchain.

OP can you post a signed message here, Just make sure to add the today's date to it and a line for "testing purpose only", and we'll see if it verifies or not.

Get Electrum.   Using a web based solution complicates matters.  The webbrowser may be encoding the text in one way and the script is expecting another.

Use cold wallet for store your btc especially with big amount, my advice is use electrum , easy to make a sign message and you don't need to download the data.

You need to provide the 'message' and the 'bitcoin address' with it for verification and I think the reason you couldn't get it verified is because brain wallet seem to be having some problem.
