' MD5.bas - wrapper for RSA MD5 DLL
'   derived from the RSA Data Security, Inc. MD5 Message-Digest Algorithm
' Functions:
'   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
' Bugs, complaints, etc:

' History
'	Apr, 17 1999 - fixed the null byte problem
' Contains public domain RSA C-code for MD5 digest (see MD5-original.txt file)
' The aamd532.dll DLL MUST be somewhere in your search path
'   for this to work
