|
|
|
A challenge (and therefore HRAm) agnostic Schnorr signature library. This is
|
|
intended to be used as a primitive by a variety of crates relying on Schnorr
|
|
signatures, voiding the need to constantly define a Schnorr signature struct
|
|
with associated functions.
|
|
|
|
This library provides signatures of the `R, s` form. Batch verification is
|
|
supported via the multiexp crate. Half-aggregation, as defined in

Any subsequent changes have not undergone auditing.

This library is usable under no_std, via alloc, when the default features are

|
disabled.
