Title: Blockchain signing message Post by: termin83r on June 24, 2015, 01:32:58 PM 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..... Title: Re: Blockchain signing message Post by: avatar_kiyoshi on June 25, 2015, 01:33:18 PM What wallet you used for sign message? Are you sure about your private key?
Verify your message here: https://brainwallet.org/ Title: Re: Blockchain signing message Post by: Quickseller on June 25, 2015, 02:11:34 PM https://bitcointalk.org/index.php?topic=990345.0
^^^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. Title: Re: Blockchain signing message Post by: termin83r on June 25, 2015, 02:58:34 PM 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 :/ Title: Re: Blockchain signing message Post by: favdesu on June 25, 2015, 05:16:56 PM I use 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. Title: Re: Blockchain signing message Post by: sdp on June 25, 2015, 06:41:37 PM 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.
