Re: How to sign a message?!

How can I sign a message in the new blockchain?It seems I can't find a sign button there,I've only seen the verify one.It's not in the manage options.

By blockchain I assume you are referring to blockchain.info

To sign a message, go to the "Settings" tab on left, Click on "Addresses", Click on "More Options" in front of your required address, Choose "Sign Message" .

Does the new version allow signing messages? My last info is only the old wallet version does.

Yes it does allow signing.
I don't use blockchain.info much, but the steps above do work for latest version too ! I checked yesterday only.
It's here :

You may update the OP

I believe it will only work for the imported addresses, try to make new address and sign a message with it!

If you make a new address in the new blockchain also do not work for sign message. It actually work for imported address. I do not know why the blockchain make this not available to sign message there with new address.
