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.
