Description

This feature submission implements new hash algorithms into ZFS with improved performance:
  • SHA-512/256: 50% higher performance than SHA-256 on 64-bit hardware with minimum code changes.
  • Skein: 80% higher performance than SHA-256 with new and highly secure algorithm. Includes a KCF SW provider interface.
  • Edon-R: >350% higher performance than SHA-256. Lower security margin than Skein, but much higher throughput.
    To address the potential security implications of Edon-R, this feature submission also implements salted checksums (aka MACs) in ZFS (both Skein and Edon-R utilize this).
