• File src/OFSHA1Hash.h — part of check-in [e629dc83a9] at 2019-12-27 00:41:54 on branch trunk — OFSecureData: Add allowsSwappableMemory property

  With this property, it's possible to specify whether the memory should
  be protected from swapping or not. This makes it easier for e.g. the
  crypto hash classes: They can now just always use OFSecureData without
  wasting unswappable memory if it's not needed. (user: js, size: 1183) [annotate] [blame] [check-ins using]
