# schnorr signatures + musig2 (N/N multisigs)
Simple zig implementation of [Schnorr Signatures](https://en.wikipedia.org/wiki/Shamir%27s_Secret_Sharing) and [MuSig2](https://link.springer.com/chapter/10.1007/978-3-030-84242-0_8).
Implementation partially inspired by [https://github.com/VictoriaGrasshopper/schnorr_signature](https://github.com/VictoriaGrasshopper/schnorr_signature)
Includes a CLI app for independent/one-time using of schnorr and musig2 signing.
