Fixed-base key generation #289

Closed chris-wood closed 3 years ago

chris-wood commented 3 years ago

The group generator is currently fixed throughout the protocol, but it may useful to let applications vary this. It seems reasonable, for example, to let the public key base be something other than the fixed generator, such as HashToGroup(something). Currently, the public key assumes that the base is the fixed group generator, which is convenient though (I think) not essential.
