Hash-based signature use small private and public keys, and they have low computational cost; however, the signature values are quite large.  For this reason they might not be used for signing X.509 certificates or S/MIME messages; however, sine hash-based signature algorithms are secure even if a large-scale quantum computer is invented.  The low computational cost for signature verification makes hash-based signatures attractive in the Internet of Things environments, and the quantum resistance makes them attractive for the distribution of software updates.
