Methods

FinalUse this function when you are done adding bytes to the MD5 class.
UpdateUse this method to add data to the MD5 stream.

Test case for a known test vector

Dim data as String
Dim hash as MD5
Dim result as String
Dim hexResult as String
Dim i as Integer

data = "message digest"

// We do this in ASCII because the well known test vectors come in ASCII
data = ConvertEncoding(data,Encodings.ASCII)

hash = new MD5()

hash.Update(data)

result = hash.Final()

// Convert to HEX
For i = 1 to 16
    hexResult = hexResult + Right("0"+Hex(Asc(Mid(result,i,1))),2)
next

if hexResult = "f96b697d7cb7938d525a2f31aaf161d0" then
    return true
else
    return false
end if
