Hash functions (H) in Crypto Go

H cards allow building Crypto Set CS3 (Integrity + Authentication) when combined with an appropriate MAC card.

H combined with a MAC, to build a CS3

Crypto Go contains 13 H cards, considering the following 11 concrete tools:

  • SHA-2 256, 384, 512, 512/256
  • SHA-3 256, 384, 512
  • SHA-3 SHAKE128, SHAKE256
  • Whirlpool 512
  • BLAKE
  • RIPEMD-160
  • SHA-2 224, 512/224
  • SHA-3 224
  • MD5 128
  • RIPEMD-128
