  I'm not aware of any such API, but CorSym.idl defines 2 standard GUIDs (whichare exactly the two possible algorithms that IDiaSourceFile::get_checksumType can return):
  

  /* ------------------------------------------------------------------------- *
   * Guids for known Source Hash Algorithms
   * ------------------------------------------------------------------------- */
  cpp_quote("EXTERN_GUID(CorSym_SourceHash_MD5,  0x406ea660, 0x64cf, 0x4c82, 0xb6, 0xf0, 0x42, 0xd4, 0x81, 0x72, 0xa7, 0x99);")
  cpp_quote("EXTERN_GUID(CorSym_SourceHash_SHA1, 0xff1816ec, 0xaa5e, 0x4d10, 0x87, 0xf7, 0x6f, 0x49, 0x63, 0x83, 0x34, 0x60);")
  

  
  So just checking against one of those guids should be sufficient for your purposes.
  
  I think the reason diasymreader (ISymUnmanaged* APIs) uses a GUID instead of the simple numbers used by DIA (which DiaSymReader is built on top of), is that DiaSymReader can also be used to write PDBs - so there is no central authority for all possible values here (unlike for native PDBs which only Microsoft tools can generate).
  
  Hope this helps,
  Rick
