JotaSigs (Hash-based Signatures)

JotaSigs is a Python implementation of hash-based, one time signatures (OTS). OTS serve as primitives employed to construct more general signatures schemes. On its own, a OTS can only authenticate one single message per public key. In conjuction with another scheme (i.e., XMSS) the OTS primitive can be turned into a many-times, general purpose signature.

Hash-based signatures are post-quantum: they are designed to be used on classical computers, and are thought to be resistant even against an attacker with a quantum computer, since they only rely the security of a cryptographic hash.

The Jotasigs library includes two primitives:

Important: the library is currently in beta, and is intended for use in education and research. Use with caution. Its use in production is not recommended yet.
