Can't add custom message to blindly sign with protocol_a01 #228

Closed oscar-king closed 4 years ago

oscar-king commented 4 years ago

In the protocol the message that is blindly signed seems to be hard-coded into the methods:

epsilon = self.group.hash(zeta, zeta1, alpha, beta1, beta2, eta, "msg")

and 

p2 = self.group.hash(zeta, zeta1, tmp1, tmp2, tmp3, tmp4, "msg")

@oscar-king Could extend the protocol impl to include the input message via a command-line flag? I guess there are different ways to support custom messages. Feel free to submit a PR. Thanks!

@jakinyele True. Thanks for the reply!
