JAVA Programmer
The repository contains open source Java code that works. You can use it in your programs, get advice, support, order Java code modification, invite a Java programmer to the team.
The repository contains not only projects, but also individual modules (classes and methods) from which you can create interesting applications.
A programmer with a large number of ready-made Java modules can save a lot of time and money when developing Android Studio projects.
Data protection
Hackers routinely obtain data about firms' clients. This is not pleasant and can ruin the business. However, if the stolen data is encrypted using a strong military-grade algorithm, then nothing can be done with such data. Therefore, you should send data from the client smartphone to the server in encrypted form and write it to the database without decryption.
But you can say that hackers can access the server and use the available software to decode the data. As if they are company employees or a server administrator. But for employees, nothing but the last name of the client's name is deciphered. Address, phone, email, purchase and payment history, card numbers - everything remains encrypted.
Private Key
But hackers can get the private key and decrypt the data, you say. But you can obfuscation the encryption keys, make it invalid, and generally remove it from the server. You just need to know how to do it.
This is very important when you use cloud storage or rented servers in Data Centers. A database backup can be lost, stolen or copied.
But if the data is encrypted with an additional strong algorithm, you will be much safer for your business.
It is clear that Android examples and Java code in GitHUB only show areas of interest in programming, but in no way reflect the programmer's creativity.
Custom encryption systems installed in addition to standard protection systems make it much more difficult to analyze the code, data and logic of your software.
National alphabets
To support national alphabets (NA) during encryption, it is necessary to transform texts. Java code is also developed for this. The same transformation can be used for obfuscation as well.
This Java code allows you to store texts in any language in the database. Encrypt and decrypt.
JAVA Programmer >> NA >>
Android SQLite
Examples from Android SQLite. First, a simple Java code. Then we will add more SQLite requests, then we will add data encryption. Then we will export the database.
A ready-made application for working with a SQLite database and with RSA encryption of record fields, generating, saving, restoring, exporting and importing encryption keys, editing, paging, adding records, supporting encryption of large texts, exporting and importing a database.
SQLite RSA >>
This is a great base for your Android Java applications with a high degree of readiness.
Previous professions: Assembler, PHP, HTML, VB6 programmer, network engineer, engineer for control and orientation systems of an orbital space station.
