XMSS reference code
This repository contains the reference implementation that accompanies the Internet Draft “XMSS: Extended Hash-Based Signatures”, draft-irtf-cfrg-xmss-hash-based-signatures.
This reference implementation supports all parameter sets as defined in the Draft at run-time (specified by prefixing the public and private keys with a 32-bit oid). Implementations that want to use compile-time parameter sets can remove the struct xmss_params function parameter.
While the behavior of the code in this repository is supposed to be stable, the API is not yet fully complete. In particular, the wrapper for run-time parameters does not yet support the back-end functions that make use of BDS traversal (TODO). We will also add more extensive test functionality, making it easier to compare to other XMSS implementations (TODO).
When using the current code base, please be careful, expect changes and watch this document for further documentation.
