• File src/OFSHA224OrSHA256Hash.h — part of check-in [a1931f59a2] at 2014-09-01 23:42:55 on branch trunk — Add OFSHA224Hash

  This creates a common base for OFSHA224Hash and OFSHA256Hash so that all
  code (except the different initialization constants) is reused. (user: js, size: 938) [annotate] [blame] [check-ins using]
