The BCArchive software is designed to compress a group of files/folders to a single encrypted file. Using BCArchive is very simple yet very secure. Let's say you want to back up some data and store it as compressed, encrypted archive on your hard drive. All you need to do is specify a password for the archive when you create it and enter the same password to decrypt and extract the data. This simple process requires no special knowledge of encryption.
