[MBS] Using MD5StringMBS with huge files

[Heinz]

Hello,

is there a way to calculate the MD5 hash for a huge file using chunks?

For CRC32StringMBS  I've this example that uses chunks:

  b = f.OpenAsBinaryFile( false )
  crc=0
  data=b.read(1024*1024) '**read 1MB Chunks
  while data<>""
    crc=CRC32StringMBS(crc, data)   'CRC32 for all chunks
    data=b.read(1024*1024)          'read next 1MB Chunk
  wend


 For MD5StringMBS I've only found a sample that suggests to read the entire 
file like this:

 b = f.OpenAsBinaryFile( false )
 data=b.read(b.Length)  '> 1GB ?
 md=MD5StringMBS (data)


This is problematic if you need the MD5  for huge files (> 1GB)

So is there a way to calculate the MD5 value for a file using chunks (like 
with CRC32) instead of reading 1GB or 10 GB into a string variable... ?

I use Windows XP and Plugins 11.3

thanks
