We should not use the same password to different portals.The discharge of one of them threatens us to lose data in many places.Therefore, in order to minimize this danger, we should use two-step authentication (ang.two-phase authentication) - 2FA (which is not part of this project) and different passwords.In this second, Password Manager programs such as Bitwarden or KeePass can help us.The project consists in creating a console application to modify and read from a file in which our passwords will be stored along with additional information about the various portals to which these passwords concern.They will be encrypted with a single main password.The application should be launched from the command line level (ang.The command line.Based on the commands read from the keyboard to perform the relevant functions and return the information that interests us - on the basis of the command line interface (ang.Command-line interface) - CLI.Functional requirements After the program is launched, the user should be able to choose one of the files in the program folder or provide a direct, absolute path to the file.The chosen file will be called the source file.The data in the source file is encrypted.The method of encryption must be authentic and fully understood.The source file password is intended to be an unnecessary honor to the encryption and decryption process.The difficulty of breaking such a code will not be assessed, but the opening of the file in the text editor and simple deduction methods should not be sufficient to decrypt its content.The same applies to the modification of its content.Any attempt to decrypt the file should save the timestamp of such a operation.Since the file itself and the program does not store anywhere information about the correct hash, and the timestamp of modification must always be changed (both during the failed attempt to open and modify the file (to give a different password than that of which the source file is encrypted), it will be the only information openly recorded throughout the file (without encrypting).Therefore, we need to find a different way to hide it.One of the possibilities would be to distribute this information into different lines.The beginning of line 11 could be hhDDDD, line 22 mmDDDD, and 33 ssDDDD, where hh is the hour mm is the minute and ss is the second of the last decryption trial.DDDD is further encrypted data that has nothing to do with the timestamp itself.Each password must contain at least: Name (the own name of this entry, for example."Word to Google Account1"); Text representing the same password; Category.Any password can also contain: Website / Service; Login.Implementation of all these elements is required, although not every password must contain the last two components.They must be optional.Opis the command Search for the password - returns the passwords that contain specific parameters.Shorten the password - returns the shortened list of all the passwords.It is designed to be able to rate at least 2 different parameters at the same time, i.e. by name and category.Add a password - it adds a new password to the encrypted file.The user should be able to enter his own password and inform him how safe it is and whether it has not been used before.Additionally, you should offer him a password generated automatically, giving him the possibility to select certain parameters, such as: Number of characters; Whether to contain large and small letters; Whether to contain special characters.Edit the password - allows you to edit the data in an already existing hash.Remove the password - removes the chosen password or password.Before each deletion, we should notify the user of this, especially if more than one password is deleted.Add categories - adds a new category that we will be able to use when creating new passwords.Remove categories - Removes categories with all the passwords that are attributed to this category.Password editing cannot be done by removing the original record and replacing it with a new.
