SQLite database prototype for Android with support for RSA-encrypted records. The application can create a database, check in, delete, delete and register most of the database, and export/import the database. The application can generate, heal, restore, export and import takeover keys. The database has 8 fields in each entry. One field is encrypted using RSA. For RSA encryption, method 2 has been added to encrypt/decode large texts. An application can scroll through an Activity. This project is a good template for an essential database on trade, women, partners. You just need to enable and configure the necessary features and create a look. The Java code has great comments. Supports RSA encryption with a long key of 1024 or 2048 bits. You can choose the size of the encryption key. Also, you can use obfuscation. To do this, there is a special method in which you simply perform your secret actions. Owerview - https://docs.google.com/document/d/1VzJr0YVOun0mtGTyCn4uQwsNllINjqg_mc2qq_5FvVM/edit?usp=sharing

(16.11.2022) Methods for encrypting large texts have been tested on a prototype. Now I'm adding to this project. (18.11.2022) Add GUIDE.pdf - pdf guide (23.11.2022) - Debugging (24.11.2022) - GUI Updated (27.11.2022) - Zero text to ecrypt error detected (28.11.2022) - Fixed bug with text processing before encryption (28.11.2022) - Let's move database operations to a separate thread. We will do the same with encryption/decryption. For this, I made a separate application project. The project will not be added to the repository. (30.11.2022) - Work with streams is done in a separate project. If someone needs it, you can add. For now, let's add a few more fields to the database records. To increase the universal properties of the application. And then we'll add image display for records in the SQLite database. (01.12.2022) - 4 more fields have been added to the database (now a total of 8 fields). The next part of the project is adding a function for working with pictures in JPG format (04.12.2022) - Fixed bug (05.12.2022) - Developing Java code for uploading images to a SQLite database (07.12.2022) - Java code for loading images was written and separately debugged. (11.12.2022) - JPG load into SQLite debugging (12.12.2022) - JPG load method testing (14.12.2022) - Unwritten methods for the SQLite extension - SQLiteBoost. Let's add it to the class, but we won't "connect" it. Everything is simple there. If the database lacks fields, and there are already a lot of hashes, then these methods will easily fix the problem.
