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.	11 years ago

Ryan X. Charles	46271de06e	add some basic sanity tests for signatures and key generation Signing a message with ECDSA involves using a random number, and this means that two signatures should never be the same. This commit adds some basic tests to Key.signSync and Message.sign to make sure this is the case. Also, a new bitcore.Key should never have the same private key twice. This commit also adds a basic test to make sure that is the case.	11 years ago
Ryan X. Charles	659dc10f96	add support for signing/verifying messages This adds a new Message class with static methods for signing and verifying a message the same way as bitcoind. (In a nutshell, messages a prepended with "Bitcoin Signed Message:" before being hashed and signed). There is one important piece missing ... verifying a signature with an address, and not a public key. I have not yet implemented this because the cryptography interface of bitcore does not allow me to derive the public key from a signature. This will need to be added before verifying from an address is possible.	11 years ago
