I was studying a little about PGP. I am a total newbie at it.
But there are so many similarities to PGP and Bitcoin. Is it possible to encrypt a message using my public key, and decrypt it using my private key? Like PGP does. It would be something very nice to do, as Bitcoin clients are much more common and widespread than PGP related software (also easier to use).
I would like to be able to encrypt my messages using bitcoin key pairs. It would be really useful.
Maybe in future Bitcoin signatures could even replace PGP signatures? Is there any discussion about this? Or is it technically impossible ? I searched but couldn't find any.
I like the thought of using blockchain as a part of information security. The main goal is to maintain confidentiality while providing accessibility. However PGP is rather old. Are you also asking if we should integrate the complexity of the blockchain to add more security layers to the protocol for making informational or simple contract transactions (not just monetary) more secure?
