Title: Encrypt/decrypt arbitrary text using bitcoin keys! Post by: phelix on February 19, 2013, 08:10:46 AM It is possible to encrypt/decrypt messages with the bitcoin keys.
Maybe you are aware of the PyBitmessage project by Atheros: https://bitcointalk.org/index.php?topic=128230 Its code can be used to do this: Code: #!/usr/bin/env python I am not a cryptographer but from what I understand it should be possible to make this really secure (not sure about the state of the libraries at hand).

So yes is extremely secure. ;D Title: Re: Encrypt/decrypt arbitrary text using bitcoin keys!

So yes is extremely secure. it is posible but lets take that idea one step further ? The issue with ssl is that you need to send public key from a server to the client. Having these key's stored in a block chain would make the whole system a lot more secure sins it would become nearly impossible for a man in the middle to send false key's to a client that checks a block chain for valid keys. At the same time it would would eliminate the all powerful CA's that have been know to hide and/or deny hacks and leaked private key's. Yes / No ? If only I had time/knowledge to implement something like that ... but a man can dream right. Title: Re: Encrypt/decrypt arbitrary text using bitcoin keys!

Yes / No ? there is even a small bounty available for implementing it: https://bitcointalk.org/index.php?topic=117795 Quote If only I had time/knowledge to implement something like that ... but a man can dream right. +1 :) |
