Simple way (unique PHP file) to store your encrypted data in a single text file, not using database at all and encrypting from the client side using javascript AES algorithms. It also generate 6-digit TOTp codes (see below).
Current version: 2020.06.15 - Changelog
Copy this project in any PHP 5+ server and call it from browser. Default encryption key "1234". Each time you decrypt, you can change key and re-encrypt and save. You must remember that the encryption key is not saved ANYWHERE, so you must take care by yourself for not forget it!
To access to the index.php menu file of the interface you will submit a password in the login.php page. So, you must previously embbed in that file the md5 hash of your preferred password, inthe first lines of that PHP file.
On the directory /data you can put as many data files you need. Then the index.php show at home a list of the files included in that directory. The name of those files cannot contain dots or inclined slashes (. / \ ) due to security reasons. It will be recommendable only to use letters, numeric digits and horizontal slashes.
if you use a data file to store a JavaScript Object (like the backup export file of the browser extension Authenticator ) then when you decrypt it appears a list of 6-digit TOTp codes generated by the list of accounts contained in the data.
This picture below show an example of the kind of data. The app is ready to understand the exported backup of that Firefox addon, but you can write mannually the list of accounts whenever you include for each one: a label "account" and a "secret" key, at least. The other properties are optional and useless for this app.
The app doesn't automatically regenerate the codes neither show a countdown indicator. You must click over regenerate button to update 6-digit codes.
You're welcome to use it. I use it since long time ago for save all my important private data, hosting a copy of this project on one of my servers. Please, if you make any improvement, request a pull ;)
