SecurityPkg: add RpmcLib and VariableKeyLib public headers

[mirror_edk2.git] / SecurityPkg / Include / Library / HashLib.h

/** @file\r
  This library abstract TPM2 hash calculation.\r
  The platform can choose multiply hash, while caller just need invoke these API.\r
  Then all hash value will be returned and/or extended.\r
