XMSS reference code

This repository contains the reference implementation that accompanies RFC 8391: “XMSS: eXtended Merkle Signature Scheme”.

This reference implementation supports all parameter sets as defined in the RFC 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.

When using the current code base, please be careful, expect changes and watch this document for further documentation. In particular, xmss_core_fast.c is long due for a serious clean-up. While this will not change its public API or output, it may affect the storage format of the BDS state (i.e. part of the secret key).

Dependencies

For the SHA-2 hash functions (i.e. SHA-256 and SHA-512), we rely on OpenSSL. Make sure to install the OpenSSL development headers. On Debian-based systems, this is achieved by installing the OpenSSL development package libssl-dev.
