Security and SQL injection.

I want to learn more on the topic of security. Im building an app for Android. It is a simple chat application. I want to know what is sql injections and how can I secure my app from them! Does RSA Cryptography protect the app from the warning of stealing data by 3rd person?

SQL Injection is a type of aninjection attack that makes it possible to execute malicious SQL statements. These statements control a database server behind a web application. Attackers can use SQL Injectionvulnerabilities to bypass application security measures.

Not the most ideal place to search - SoloLearn focuses on programming. What you're looking for are security measures. To understand SQL injection, you need to know SQL first. There's a course here you can take. As for cryptography; different field as well. It's all math - in a programming sense, you're dealing with complex calculations. Your question focuses on 3 elements that you need to be proficient at if you really want to build a proper secure app: Android development (Java), Cybersecurity (Basic SQL and SQL Injection, and Cryptography (Encryptions).

To avoid a sql Injektion you'll need to scan the things your users are posting for escape Charakters or the easier solution is to convert every input into htmlchars before processing them. By encrypting them your only protect the data if the attacker is already in your database
