You can't decrypt a signed message unless it was decrypted before signing. You can verify the signed message. You can use your wallet or you can use brainwallet.github.io/#verify to verify.

You can encrypt/decrypt a message using your public key of your BTC address using Electrum. I don't know other wallets which have encrypt\/decrypt messages feature.

First if you're gonna sign an address you need to own it (You've to know it's priv key).

Then open the verify tab and copy the details: "Message, (public)Address and signature".
When you click the verify button it's gonna say to you it's verified or not.

I used electrum for that, you can use anything else.



Also I used blockchain.info wallet to verify this message:


message: Hi chronicsky!
address: 12ia5dhAvUf2VTqe1fRnBVbq4Je7N5EHmL
signature: HI7bPPL1m/dI9FAi37Z/k5QsaKjhlmsi8ncAavbrvq9+dQgKr2CScgy8I6AEM0DHQXaP/0k8jlkGkexMefAT4UY=


This method is used to prove ownership of an address.

Okay so this way it can be verified
Cool! thanks
I don't think blockchain.info has encrypt/decrypt feature but sign message

I don't use Electrum but blockchain.info
I do understand signing a message , adding address and public key now (thank you)
But i can't find anything about verifying on blockchain.info

Go to 'Receiving' tab and then click 'Advanced Options' near 'New Address' and then click 'Verify Message'. I don't remember correct words but you got an idea. You can find a German post by shorena here : https://bitcointalk.org/index.php?topic=920631.msg10425511#post_bcifeb2015. You can easily understand as there are pictures in it.
