Different files could be protected with different passwords and the level of security normally depends on the algorithm, password length, and character combinations. Another more secure way is to encrypt the file system so, in order to access any of the object files or folders under the file system, the right keys or passwords (or a combination of them) need to be supplied. Such method has the advantage of protecting all the target files and folders with “on the fly” decryption. Also, modern encryption algorithm makes hacking or decryption rather impossible without the original password or keys. Some may even choose to protect the whole data media before one is allowed to access it for reading or writing operation. Such implementation normally has the consensus agreement from all the media manufacturers covering all security issues. By passing such security pose a real challenge. Having your data, file system or data media secured with the password or key is a good way to prevent unauthorized access. But losing or forgetting your password or keys to your protected data and files could be your worst nightmare.
