How to sign a message?!

[tarsua]

To the dude who just read the above message and then tried to log in to my wallet: I have 2FA turned on and your ip is logged at two sites.

Firstly, verified, secondly, someone cant use that to try to log into your wallet, they probably have access to your identifier

Why is this not stickied? have you asked the admins to make it a sticky OP?

Why is this not stickied? have you asked the admins to make it a sticky OP?

apparently most topic that gets stickied is about the forum (rules, guide, etc.). tho this thread should really get stickied since a lot of newbies asks about signed message almost everywhere.

No, I have not asked the admins. I dont know, it feels strange to ask for my own thread to get stickied. Maybe create a thread about it in meta and see how others react to this.

Added to the Unofficial list of (official) Bitcointalk.org rules, guidelines, FAQ:

Q: My account was hacked! What do I do?
A: See this thread: https://bitcointalk.org/index.php?topic=497545.0. If you don't know how to sign a message, see this thread made by shorena: https://bitcointalk.org/index.php?topic=990345.0

Also, remember when PMing the signed message, send it in [code ][/code ] brackets (just without the space at the end). For example,

Code:

-----BEGIN BITCOIN SIGNED MESSAGE-----
My account <account> has been hacked/lost. Please reset the email to <email>. The current date is <date>.
-----BEGIN SIGNATURE-----
<insert address here>
<insert signature here>
-----END BITCOIN SIGNED MESSAGE-----

Here is the unedited post where I posted that address: ...
OR
I sent that address to someone in a PM with PM ID#...

If you don't know how to sign a message and the tutorial mentioned before didn't mention your client, google for some tutorials with terms like: "signing messages with <insert your bitcoin client name here>". For example, "signing messages with bitcoin-qt".

Keep up the great work.

Hi dear you are doing very good for this forum. I really appreciate your work. I got much help from your this post.

my thought is that you cant sign a message directly from the exchange; you need to control the private key of that address, so i think the only workaround here is to get the private key from the exchange (if they provide it, which its likely they wont) and import it to your own wallet to sign the message.

That's right, if you own the private key. It meant the wallet is yours, and you can do anything you want with the wallet. So it just possible if you have the private key.

I tried to create a signed message with my coinbase wallet seeing the suggestions at this thread. But at the end, when I sign the message nothing happens. How I must continue? Where I can find the signed message? In which way i can send it in an email address?

Coinbase does not provide a finished format you can just copy paste AFAIK.

If you follow their how to here -> https://support.coinbase.com/customer/portal/articles/1526413-how-do-i-sign-a-message-with-a-bitcoin-address-

The message is 5 in the last picture and the signature 7. If you want to use the format suggested here you need to copy it.

Code:

-----BEGIN BITCOIN SIGNED MESSAGE-----
<insert message (5) here>
-----BEGIN SIGNATURE-----
<insert address here>
<insert signature (7) here>
-----END BITCOIN SIGNED MESSAGE-----

-----BEGIN SIGNATURE-----

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

Sorry but you must be patient with me. I don't know what is AFAIK. I don't know how to create the format of the message under the "Code" (how is created the box with BEGIN BITCOIN SIGNED MESSAGE etc).

How is created this:

Code:

-----BEGIN BITCOIN SIGNED MESSAGE-----
<insert message (5) here>
-----BEGIN SIGNATURE-----
<insert address here>
<insert signature (7) here>
-----END BITCOIN SIGNED MESSAGE-----

I must copy from here the writing with capitals (or create myself this format) and then put the other data and then put all between the writing code? Or how?

And what is important the signature 7 cannot be copied. I righ click with my mouse on it but the option to copy is not appear.

Thanks!

AFAIK is short for "as far as I know". I sometimes use it when Im not 100% sure.

I don't know how to create the format of the message under the "Code" (how is created the box with BEGIN BITCOIN SIGNED MESSAGE etc).

How is created this:

Code:

-----BEGIN BITCOIN SIGNED MESSAGE-----
<insert message (5) here>
-----BEGIN SIGNATURE-----
<insert address here>
<insert signature (7) here>
-----END BITCOIN SIGNED MESSAGE-----

You have to do it yourself. If your address is A, the message you wrote is B and the signature that coinbase created for you is C you copy paste the above like this:

Code:

-----BEGIN BITCOIN SIGNED MESSAGE-----
<insert message (5) here>
-----BEGIN SIGNATURE-----
<insert address here>
<insert signature (7) here>
-----END BITCOIN SIGNED MESSAGE-----

and replace the parts with A, B and C, like this:

Code:

-----BEGIN BITCOIN SIGNED MESSAGE-----
B
-----BEGIN SIGNATURE-----
A
C
-----END BITCOIN SIGNED MESSAGE-----

I must copy the writing with capitals and then put the other data and then put all between the writing code? Or how?

Yes.

And at the end the signature 7 cannot be copied. I righ click with my mouse on it but the option to copy is not appear.

Thanks!

This might be a browser issue. I can tripple click the box in chrome and rightclick copy the signature.

Everything clear. A big thanks!!!!

The image^[1] and similar format in the tutorial might be misleading to newbies. A few users started posting signed messages like it. Eg:-

Code:

-----BEGIN BITCOIN SIGNED MESSAGE-----
<This is shorena from bitcointalk.org and today is the 24th of April 2015. I publish my guide to sign message with bitcoin addresses and all related pictures under CC BY-SA 3.0 link to guide : https://bitcointalk.org/index.php?topic=990345.0 link to license: https://creativecommons.org/licenses/by-sa/3.0/>

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

I think if you put a note there mentioning to ignore '<>' signs maybe good.
