Can someone be fooled into creating a signature for an address that releases funds from that address?
(Or do tx signatures and "ordinary" signatures follow different encoding?)

Just added multibit HD 0.1 as it was now officially replaced on their homepage[1]. Very nice wallet. It has no list of available addresses. Thus if you want to sign with a specific address just copy the address into the box.

The signed message comes with a header, which you can remove.

Hello, thank you for your exaustive guide, very strong and helpfull.
I have some question, first how can I "claim" an address here on btc talk?
And if I have related to me an address that is full of btc, if I sign a message I will show the private keys and potential can I lost the coins?
If yes, how can avoid this issues?

sign messages proves that you own a specific address and you don't need to show the private keys because you're potentially showing people how to get into your wallet. Just do the steps and show it to the person who is requesting it and this will prove that you own the wallet with funds

not sure if I understand your question there. you can't just "claim" any address. and you only need to use your private keys to generate the signed message, nobody will see it unless you included it on your message. so there's no risk of losing any coins.

Wow, this is a great tutorial shorena! I think mods should sticky this, because every new user have to learn this basic thing before it's too late. I see a lot of users got hacked or lost password and they end up losing their account forever.
Dude awesome tutorial.
Signing with bitcoin is a pretty secure system and it needs more adoption IMHO, this will hopefuly make it more commonplace.
I was thinking about writing a tutorial for this within the week but you already took my place so TY for saving me some work

how to sign a message with earlier date?
I am not entirely sure I understand you, but the message you sign is up to you. The sig itself does not contain a date as a PGP sig would. If you want to sign "Im efesmalt and today is 1875 March 15th" you can. You can sign any message you want, the only question is what you want to accomplish with it.

You sir.. Are a pimp and a scholar for posting this.
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.
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
Which wallet/service are you using? If there is any wallet or online service I missed, I will ad it. I know Im currently not covering all wallets and services, but I am a bit swamped lately. Regardless of this if someone needs a guide for a certain wallet or service I will certainly take a few hours to make it.
I used online wallet Sir. My primary is coins.ph , the btc online wallet provider here in our country but it doesn't have a sign message feature . I make another online wallet and I choose XAPO. I used this two for receiving and paying funds.I dont have an idea about signing a message until I visit the "Stake your Bitcoin Address Here" thread. Never heard of blockchain.info the time Im new to BTC world.
Oh, I see. AFAIK neither XAPO (I checked that in the past) nor coins.ph (just did a quick check, did not download their app though) allow a signed message.
You dont have to switch wallets just to be able to sign a message though. If you are happy with your service you can stick with it for your coins and create an blockchain.info acount (or better install a local wallet software) just for signing. Sometimes its important to sign with an address that actually has spendable coins associated with it, but thats only if you need to proof funds. If you install a software make sure its not bitcoin core or armory as they will try to get a full copy of the blockchain. You dont need that to sign a message. Multibit or Electrum should work fine.
Yeah I really like to signed my address which I always used and Im happy with the services of my online wallet provider especially coins.ph because it has many features and we can pay bills directly using that provider. I'll try MultiBit and Electrum. Many thanks for answering my query.
