There is a difference between password protection and password encryption, even though they may sound alike.
Password protection is like locking something in a safe-deposit. It means no one can get to the locked content without knowing the right combination. This method is used on separate documents, folders, and other data a computer user may want to protect from other people who might have access to the device. With password encryption, you are creating a password AND encrypting the contents of the file. It is a process during which the content one wishes to keep secret is altered to make it unrecognizable. For example, if it is a text document, letters of each word might be shuffled with additional characters so the words would no longer make any sense. The reverse process is only available if the person who wants to decrypt this data can provide a specific decryption key or a password. In other words, even if the password is removed no one could read the hidden content as it still would need to be decrypted. Of course, it is important to realize you might be unable to retrieve it too if you lose the decryption key, aka, the password.No doubt it is safer to use password encryption since it provides two security layers and password protection has only one. Nevertheless, it usually depends on the data one wishes to protect and the people one wants to keep it away from. For instance, if you want your kids to be unable to open less important documents or other information, you could password protect it with a secure password made up from random characters; something they could never guess. On the other hand, if we are talking about sensitive data the loss of which could do damage to your virtual security, password encryption would be indicated.
Since Notebooks are the containers for EN documents and media, one or both methods are necessary at this "container" level. At a minimum, at least one of these methods is necessary at the Notebook level.
EN needs to introduce Notebook-level password protection to protect its users data from prying eyes. Its users have demanded it — for years — as a means of safeguarding the documents placed into EN. The use- cases are so abundant that denying this feature is like denying a lock on a door, a file cabinet or s safe. It is a breach of good faith.
