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.

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.

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.  Cool

How do you sign a message using bitcoin wallet in android app?

If you are talking about Andreas Shildbach's Bitcoin wallet, it doesn't allow you to sign message as of now.

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.

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  Grin

I am a newbie and I am so happy you guys take out the time and write such detailed information. It helps us understand so much. Shout out to all people who take out the time to help others!
