I came across this a short time ago and just recommended it to someone over in the Microsoft forum who was worried about someone getting into his files should his laptop or thumb drive get lost or stolen while on the road.
Is the author reliable? If you consider the Department of Defense reliable, then yes. Of course, since we haven't actually won a war since it changed from "War Department" to "Department of Defense" maybe there's room for doubt?
OK Link to the EW-Public Java encryption/decryption tool:
I may have slightly exaggerated the FIPS 140-2 thing, BUT probably not. The EW-Public version is not certified, but the EW-Govt version (not available to the public) does use a FIPS 140-2 certified component to do the heavy lifting. Now, encrypted files created by either version are easily decrypted by the other without any special action. This tells me the same algorithm is being used in both, just that EW-Public's encryption algorithm hasn't been run through FIPS acceptance testing.
Potential Uses (and it can be used by private individuals for personal use and by commercial companies for their work also):
Sending or storing data you do not want anyone else peeking in at. This could include:
Love notes to someone other than your S.O.
Files containing personal information of any type such as HIPPA related files, files with social security numbers and other personally identifiable info in them, confidential business records, confidential financial data, etc. etc.
Works on Windows, Mac, Linux, Solaris, and other computers with Sun Java. That's the only requirement - that you have Sun Java on the system.--
...then THINK! again.
