We've been using md5summer on Windows, which works great for pointing at a folder, generating MD5 hashes for all files and then comparing against the migrated copy.

I would like to build in some kind of checksum or md5 checking of the file to make sure it hasnt changed. Anyone have a clue how to do this in VB or know a dll/function I could use?<BR><BR>Thanks ...

If two files have the same MD5 sum, the files are exactly alike - which is why MD5 "fingerprints" can verify whether or not your downloaded file got corrupted in transit.

When Oracle publishes its next quarterly patch update in April, the company will begin treating JAR files signed with the MD5 hashing algorithm as unsigned.
