  16. 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

  17. 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) -> MD5 digest of the given string as 32 bytes string • MD5File (some filename) -> 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

  18. 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.
