I used online wallet and that's not Blockchain. Is it possible to signed a message with my primary address? I used my primary address in every transaction (not trading) that's why I like it to be signed or posting it in the "Stake Your Bitcoin Address" thread is the only way to get it signed?

Sorry for quoting. Need help. If thats not possible then maybe I'll switch to blockchain online wallet. Undecided

AFAIK the only online wallet that can sign messages are Blockchain.info. so you might want to switch to them or something better.

Thanks for the info mate. Well look like I'll siwtch to blockchain. I really like to signed a message that have code and not just by quoting. Thanks again Cool

you might want to add a timestamp.

Note: Always include the date and reason when creating a message. If you sign a generic message it could be reused by someone else.

Thank you for doing this, I was able to use your guide to figure out how to do it on Armory.

Bitcoin isn't a bubble. It's the pin!

This is a fantastic walkthrough, thank you for it. I also didnt know how to sign a message until now. When i get my beginner friends started with bitcoin, i will definitely share this thread with them!

may i ask, how to read this code

if others give code like that I'm confused how to read or how to find out that it was true Huh

I think you mean by how to verify it ?
I'm usually using blockchain 's feature to verify the signature. Just put the required BTC addy and the signature, and you will see the result instant.

The revolution will be monetized!

Some use cases for this include:
Proving your identity.
If you associate a wallet with your identity you can sign a message with that wallet. It proves that you have access to that wallet and so you must/should be the owner.

Proof of ability to pay.
Let's say your auctioning off a house at a closed auction. You only want to invite people who could actually pay if they won. In this case you could require the bidders to sign an address with at least 885BTC, the minimum price.

Why do you need to do that? It's a signature which tells us whether the message was signed by the address in question.

why do we need a sign message?

Signed message proves you have control over that address.

Quote from: zeeshsnrehman2 on May 28, 2015, 12:22:47 AM

this puzzles me everytime i see someone asking for a sign message on an account or a wallet. how to determine that the message came from the account itself?

i understood how to sign a message, thanks to shorena for that. much appreciate.

since we are following and arrow going down, how to get the arrow going up and confirm the message is from the account or the wallet?

A signed message can be verified. If a person gives you signed message claiming it was signed with address_A and if it is successfully verified, the message *was* signed with address_A. But if the verification failed, message was *not* signed with address_A and hence, the person who gave you this doesn't have control over address_A.

well then i have another question, if the account was hacked and the hacker bruteforced the email address of the person, he can sign a message with the account anytime he wants since he can change the password of the account.

i understand its a plausible level of security since everybody urges the signature on almost every deal of accounts or loans. but i havent really understood how and how to know that the message is from the account and not just random

You are mistaken. Bitcointalk account and Bitcoin address are different. You are signing with a Bitcoin address not with Bitcointalk account.

No idea, maybe to let you know that you are the true owner of the account or something like that
