I would like to verify messages using a script, not by hand.
For what I've seen, I could do that by downloading the full blockchain, and then I can use bitcoin-cli API ( this command ).

If I can't download the full blockchain, is there any other way to do that? Maybe an API service like https://blockchain.info/api or https://blockexplorer.com/api-ref

Chain Query is really close to what I'm looking for, but I need to send requests from a script

You dont need the full blockchain in order to verify a message, you can point the client at a false IP and keep it unsynced. I mostly use scripting vs. a local node[1], but a remote API can also work, e.g. blocktrail's[2] has a verify message call.

Great tutorial, very helpful for newbies who I have seen having trouble understanding the difference between signing a message and signing a post.

I dont know what 'signing a post' means, so it probably just means to post something with a signed message?

Can you make one for 'How to get a PGP Key', as well?

No. This came up often in the past, but there are good PGP tutorials and creating another one would be redudant.

Many thanks for your great tutorial. Coinomi also has the feature now, but I get an error. Maybe I must debug coinomi or similar. I wrote coinomi but haven't an answer right now. Before I do something wrong, I wait better for an advice of an experienced member here.

I think, that I need first to get somehow the private key on coinomi with backup, before I can generate a signature.

No , you can't find and signed message in app. Open it in a browser ,you can also sign a message with other wallets not only blockchain . Coins.ph doesn't support any signed message feature .Read the OP post in the firet page and follow the steps .

Thank you for your answer mate

Please excuse my noobness regarding this matter.
So when you say you can't find and sign a message it an app, you also mean to say that, like for example, in EXODUS wallet we cannot also sign messages?

i assume you are using a mobile phone and rely an apps for keeping your bitcoin.
if so then u might use mycelium apps . the steps already on the first page , just type mycelium there.
You still can use coins.ph as ur hot wallet (for daily transaction) and use mycelium only for making a signature. So if something happened to you such as your account got hijacked, you can prove you're the rightful owner and the account will back to you.

use this thread https://bitcointalksearch.org/topic/stake-your-bitcoin-address-here-996318 to post your signature and wait someone to quote your signature and verify it,
you can use it as a prove later.

Hi! I am using coins.ph . How can I sign a message using it?

Well i think it's not possible to do that, you basically do not own your private key and coins.ph it's just an exchange wallet.
Better sign a message using address that you hold/provide the private key as well.

Okay. Thank you for your reply.
I didn't have idea before that I cannot sign messages when using coins.ph.
I guess I have to use something like an app from blockchain wallet? Is it possible with that?

No , you can't find and signed message in app. Open it in a browser ,you can also sign a message with other wallets not only blockchain . Coins.ph doesn't support any signed message feature .Read the OP post in the firet page and follow the steps .

i try to sign in with my address at coinbase,nothing happens even after double clicks

You need to wait because it is normally a few seconds to wait until it appear or if the signature already appears copy it right after .If it not works try signing in different browser .I hope it helps.

Is there a way to sign a message using the new Blockchain.info wallet? In the old version it was quite easy. But in the new version, they seems to have removed this functionality. Actually, this is quite frustrating.

You can't sign messages with addressss created in new Blockchain.info wallet. If you have imported private key or if your addresses were created in old Bloclchain.info wallet, you can sign messages. If you want to sign messages with addresses created from new Blockchain.info wallet, you will have to first get private key of that address from seed (aka 12-word recovery phrase) and then import private key to a wallet or use a program only for signing messages.

https://github.com/iancoleman/bip39

I am also facing the same problem, as I can't sign messages with the new Blockchain.info wallet. How to get the private key of this wallet? I have the 12-word recovery phase with me (written down in paper).

Download https://github.com/iancoleman/bip39 and open it. Enter your 12-word seed (aka recovery phrase) in "BIP39 Mnemonic". Scroll down and you will see your addresses and private key corresponding to each one. Import private key of the address you want to sign with into a wallet such as Electrum, Bither or Blockchain.info or use a tool like https://github.com/weex/bitcoin-signature-tool. If you want to sign message with a "change" address, change '0' to '1' in "External/Internal".

I was able to sign an address using this method of yours sir.
Doesn't took long enough

thank you.

just to make sure. is this what signature looks like?

Also, I picked that address ( 1KQrcHGoo2KFNFvnkYExxJY8TUJXFgJ1QR ) on the very top list of generated addresses.
('cause there seems to be alot of addresses listed when it was generated ) won't that be a problem?
I used the BIP39 Mnemonic i had on blockchain.info.

I can't sign my coinbase Bitcoin address. I followed all the steps given in coinbase https://support.coinbase.com/customer/portal/articles/1526413-how-do-i-sign-a-message-with-a-bitcoin-address- but when I click sign message it wont create any signatue. What can I do??

In case of coinbase Id try to contact their support.

I contract to coinbase support but there is no response. It may take several days to get a response from them. So I have to wait.. as coinbase said "Notice: Our support team is currently under heavy load and may take several days to respond. Please check our help docs and forum for solutions to most problems."
