Ryan X. Charles	f87da3b5ba	add support for signing messages in compressed format ... ...this is the standard way to sign messages in bitcoin-qt. Note that the format of a compressed signature, for messages, is quite distinct from DER format, which is used in transactions. This commit also adds support for recovering the public key from a signature, which is necessary for this. The code for public key recover is taken from bitcoinjs-lib.	2014-07-25 14:07:03 -07:00
