Nonce length is fixed #42

Closed martinthomson closed 3 years ago

martinthomson commented 3 years ago

As Joe notes, we assume a fixed length. The definitions in the IETF all use N_MIN = N_MAX = 12, but the NIST publications often veer into all sorts of wild fantasies of arbitrary nonce length. This rarely works well, as we see from the analysis in 2018/993.

Closes #41.
