The desktop wallet is definitely the safest to use.
search privkey.der and pubkey.der files in your Bismuth folder then backup it.

Thanks man, sorry for plastic case broken ... if I find this i send new plastic cases.

You will get it Saturday or Monday at the latest. Sorry for the delay in shipping, there was a misunderstanding with my gf who is shipping them since I told her to wait until payment was received but forgot to tell her when you sent it. Correct, this semester might be the death of me.


Yours shipped out a while ago, you should be receiving it any day now, it did have to be shipped pretty far 

Let me know if you don't receive it by Monday and I can contact the Post Office as it is insured.


#8, 19, 20, 21, and 24 are available!

Encrypting and Signing are two different actions.

For Encrypting; the origin uses the Public Key to encrypt, and the destination uses the Private key to decrypt.  Use case, someone wants to send you an encrypted message that only you can decrypt.  You send them your Public Key (bitcoin address) and they send you the encrypted message.

For Signing; the origin uses the Private Key to sign, and the destination uses the Public Key to validate the signature.  Use case, the ICO you are talking about.  They want to verify that you are the owner of the bitcoin address, so they ask you to sign a message and forward them the signature (along with the public key -- bitcoin address).

Therefore, in your case, you only have to:

1. Copy to the clipboard the bitcoin address you want to sign your message with.  (Addresses tab, select Address, right-click and select Copy Address).  
2. Tools --> Sign/Verify Message
3. Paste your bitcoin address in the appropriate field, and write down your message
4. Click the Sign button (Electrum may ask you to enter your password to access the private key associated with your bitcoin address).

 The "signature" should appear in the bottom window.  

Provide both the message, the bitcoin address and the signature to the destination.

EDIT:  I read again your opening message and it looks like you are trying to sign a message with a 2FA wallet.  If that is the case, it is not possible to sign a message directly with your wallet.   The reason is simple, you don't have full control of the private keys associated with the bitcoin address, it is a 2 out of 3 multi signature address. Therefore, you would need all the 3 private keys to sign with this type of bitcoin address.  And this is exactly what the message is telling you: "Cannot sign messages with this type of address."

For your ICO, it seems that you would have to use a bitcoin address that starts with a "1" (not a "3").
