how do i sign a message on a bitcoin address

use this https://brainwallet.github.io/#verify

That only works if you have the private key for the address, which most exchanges won't give you. What exchange are you using OP?

im not use exchange i use blockchain that give me full acces to my address

In this case you can just sign via blockchain.info directly and dont need to export your private key to sign and in the process might leak it to someone. Give this tutorial a try -> https://bitcointalk.org/index.php?topic=990345.0#post_bci
and tell me if anything changed, so I can update it if needed.

This link (https://bitcointalk.org/index.php?topic=990345.0) was one of the first links posted, but I just wanted to vouch for it. This is a great tutorial, and it got me to understand how to sign messages.

thanks

keep passing it around. The more people know about signing a message the better for bitcoin trading.
