[BNM] MD5 quicky

[Richard Grimwood]

IIRC You are supposed to calculate the MD5 hash on the received data 
yourself and make sure it is the same as the published one. That way you 
know the file you actually received hasn't been changed. Typically used 
as a check that any files on a public ftp server haven't been 
compromised by any rampant virus/trojan.
