Im somewhat torn about the PGP guide idea. It should definitly not be in the same guide as its a completly different topic. Besides that, there are many good tutorials, e.g. by riseup for PGP best practices, setup, etc. Not sure what I could contribute to those tutorials.

I think that the easiest way is to use keybase.io , you won't have to have any knowledge about any program,it is really simple.
The bad side is that there is a long queue to get an invite,you just have to sign up and wait

Keybase.io's btc address system does not verify the address' ownership, so it is not perfect. Also you have to store private key to do things easily (and they recommend that!) which doesn't seem so good.

From what I read about keybase.io they use PGP to link several accounts to a single PGP key. They also offer to verify bitcoin addresses, via said PGP key. Can anyone with an keybase.io account verify the above? I can also check around and see if I can get an invite to dig into this.

Im not really here, its just your imagination.

I do have a keybase.io account, but I don't think adding it to this guide will help.
  • You put the bitcoin address.
  • Wait for keybase.io to save the address, (~10 secs).
  • ...
  • PROFIT!
Yes, that's all. No signature verification, no check, etc. Just enter the address and that's all.

They offer coinbase.com OAuth, but that's different issue here.

True. The two things I didn't agree with them are

 - They recommend storing encrypted PGP private key in their server.
 - They doesn't verify whether Bitcoin address is owned by the same owner of PGP key, obviously by asking a Bitcoin signed message from submitted address.

I have already proposed this but I didn't get any response from them. https://github.com/keybase/keybase-issues/issues/1400

Thanks for the answers, so keybase.io can not be used to sign a message and thus should stay out of this guide, agreed.

I just did the first few dos and don'ts. Feel free to suggest more.

I also found this very neat feature on the brainwallet page. It allows to create a link with the address, message and signature included. Creates a very long link obviously as it includes everything in plain text.

example

I think "Don't sign a message in a compromised device" should be in dos and don'ts.

Brainwallet's this update looks cool. They have automated this instead of a button. So, maybe, new pic is needed.

You can't. I highly recommend you to use a desktop(or mobile) wallet. If you want use an online wallet, use Blockchain.info. Other online wallets are insecure.

Xapo wallet does not support signing using their addresses, since it is shared (AFAIK).

Also, the reason online wallets are considered insecure is that you have to share private key with third party (think of you sharing your home key). Only blockchain.info stores private key in your device (they encrypt your private key on your computer and then upload to server, so you still have to trust bc.info to encrypt your key), that's why MZ suggested you use bc.info (or desktop wallet).

But if we stores private key in our device, it means if we lost our private so we lost everything.
That's why Xapo don't want to share the private key, so if the private key lost Xapo will refund our balance. (CMIIW)
