read my mind, I think you can avoid reading the whole file into
memory by using a DigestInputStream
<cfscript>
fis = createobject("java", "java.io.FileInputStream").init("/path/to/
your/file");
md = createobject("java", "java.security.MessageDigest").getInstance
("MD5");
dis = createobject("java", "java.security.DigestInputStream").init
(fis, md);
while (dis.read() != -1);
dis.close();
md5hash = binaryEncode(dis.getMessageDigest().digest(), "hex");
</cfscript>
** only tested this on CF9, that while() clause might blow up on
openbd, but you get the idea
