• If you need to compute MD5 digest strings for
  files or messages in your projects, this stuff
  might be useful. Remember, though, that I can
  give you NO WARRANTIES at all (this package is
  provided "as is").
• This is an active-X in-process server built
  around my original MD5 DLL using VB6. An example
  of use follows
• Dim x As MD5srv.aaMD5
• Dim md As Object
• Set md CreateObject("MD5srv.aaMD5")
• Set x New MD5srv.aaMD5
• MsgBox md.MD5String("this is a test")
• MsgBox md.MD5File("c\some file name")
• MsgBox x.MD5String("this is a test")
• MsgBox x.MD5File("c\some file name")
• Set md Nothing
• Set x Nothing

• Although it's been created in VB6, it can be used
  with any language able to create an object.
• The methods are
• MD5String (some string) -gt MD5 digest of the
  given string as 32 bytes string
• MD5File (some filename) -gt MD5 digest of the
  file's content as a 32 bytes string
• returns a null terminated "FILE NOT FOUND"
  if unable to open the given filename for input

• Besides the VB6 generated files there are two
  more in the zipfile
• read-me.txt
• Rivest-MD5.txt - original text and C source code
  from RSA
• To install and use
• 1. Unpack the files.
• 2. Execute the setup.exe program and follow the
  instructions.
• 3. Make a reference to MD5 Active-X Server in
  your projects.
• 4. Call the wrapper functions as needed.
