Downloaded Crypt3 and tested on data files, PDF files, Excel files, and photos. Running OS X (10.4.7) Worked as intended. Will buy and add to my USB sticks so I can encrypt data which I carry. Some files say that a resource fork is being removed but was able to de-encrypt the file just fine. You can rename the encrypted file as long as you only change the portion of the new file name which matches the originally encrypted file. I am very satisfied with the performance of this program.
