Detailed Description

An XMSS: Extended Hash-Based Signature public key. The XMSS public key does not support the X509 standard. Instead the raw format described in [1] is used.

[1] XMSS: Extended Hash-Based Signatures, draft-itrf-cfrg-xmss-hash-based-signatures-06 Release: July 2016. https://datatracker.ietf.org/doc/ draft-irtf-cfrg-xmss-hash-based-signatures/?include_text=1
