A free multi-platform software to manage confidential textual notes and tasks.

EncNotex is a free multiplatform software, which runs natively on GNU/Linux, Windows and macOS, that is useful to write and to manage a file of strongly encrypted textual notes and tasks. It’s aim is to grant the user an highly secure tool to manage very confidential data. For this reason EncNotex uses the AES 256 bit encryption, cipher mode CBC and SHA 512; the user cannot save unencrypted data on the disk, but only copy it in the clipboard; the required password to encrypt a file is necessarily 10 characters long or more, chosen at least from three of these four groups: small and upper case letters, numbers and other characters (asterisk, brackets, etc.); optionally, the password used to save a file could be forgotten by the software and typed again by the user each time a file is to be saved, so that the same password does not remain in the computer’s memory while the software is being used. A file of EncNotex is a textual encrypted file containing many notes (no database is used). To grant a perfect compatibility of data among the different platforms and to be very fast even with big amount of data, EncNotex has a very simple structure of notes. They cannot have pictures inside nor attachments, but their text can be formatted in bold, italic and underline. Every note has a title, a list of tags (keywords) separated by comma and space, a date and a free-length text, and can be printed. The title and the date of every note is shown in a read only grid on the left of the interface of the software, and a note can be shown selecting its title in this grid. Furthermore, in the same grid the title of a note can be indented or deindented, to make it a subnote of the previous one, or moved up and down, along with its possible subnotes. At the left of the text of the notes there is an outlook of its titles, which can be used to reach easily one of them, and of the possible tasks along with their deadline. The tasks of all the notes of a file can be summarized in a list, sorted, filtered and copied in the clipboard to be pasted in a spreadsheet, or saved in csv or ics format. It's possible to search for a note within the titles, the tags, the dates and the texts. A note or all the notes of a file can be copied in the clipboard in HTML format and then pasted in a word processor maintaining the possible HTML tags. Finally, two independent backup files are automatically created when a file is loaded and when it's saved.
