trait Sign extends AnyRef

This is meant to be an abstraction for a org.bitcoins.crypto.ECPrivateKey, sometimes we will not have direct access to a private key in memory -- for instance if that key is on a hardware device -- so we need to create an abstraction of the signing process. Fundamentally a private key takes in a scodec.bits.ByteVector and returns a ECDigitalSignature That is what this abstraction is meant to represent. If you have a ECPrivateKey in your application, you can get it's Sign type by doing this:

val key = ECPrivateKey() val sign: scodec.bits.ByteVector => Future[ECDigitalSignature] = key.signFunction

If you have a hardware wallet, you will need to implement the protocol to send a message to the hardware device. The type signature of the function you implement must be scodec.bits.ByteVector => Future[ECDigitalSignature]

  2. abstract def signFunction: (ByteVector) => Future[ECDigitalSignature]
  3. abstract def signWithEntropyFunction: (ByteVector, ByteVector) => Future[ECDigitalSignature]

    Note that using this function to generate digital signatures with specific properties (by trying a bunch of entropy values) can reduce privacy as it will fingerprint your wallet.

    Note that using this function to generate digital signatures with specific properties (by trying a bunch of entropy values) can reduce privacy as it will fingerprint your wallet. Additionally it could lead to a loss of entropy in the resulting nonce should the property you are interested in cause a constraint on the input space.

    In short, ALL USES OF THIS FUNCTION THAT SIGN THE SAME DATA WITH DIFFERENT ENTROPY HAVE THE POTENTIAL TO CAUSE REDUCTIONS IN SECURITY AND PRIVACY, BEWARE!
