Use Keychain for sensitive credentials, Core Data for structured app data, and Realm for secure, cross-platform storage. Always enable encryption, store keys in Keychain, and avoid saving secrets in plain text. We recommend combining these approaches, each fills a security…
Building secure iOS apps starts with disciplined coding practices, not guesswork. Strong type checking, strict input validation, and relying on trusted platform APIs are non-negotiable. Credentials must stay in the iOS Keychain, never in plain files, and HTTPS should be…
Protecting sensitive user data in iOS starts with writing secure code and following proven practices. That means using trusted APIs, validating every input, and never storing secrets in plain text. The iOS Keychain is the right place for sensitive data,…
Use smart memory tools and safe types to dodge security bugs. Favor standard containers and guideline-backed patterns over manual memory tricks. Always check input, test thoroughly, and let the compiler help you keep attackers out. Key Takeaways Memory and Lifetime…
Use format specifiers and error checks to keep user input safe. Verify input ranges every time, and always clear buffers after mistakes. When parsing numbers from strings, we double-check types and never trust input blindly. Key Takeaways Reading and Validating…
In the world of systems programming, especially in C and C++, string manipulation is both essential and risky. The standard library offers a suite of string functions, but not all of them are designed with safety in mind. Many serious…
Race conditions are among the most frustrating and elusive bugs we encounter in multithreaded C/C++ applications. At first, they may seem like phantom issues , disappearing when we try to observe them, and surfacing when the system is under load…
Working with files in C is deceptively simple. You call fopen(), read or write, then close it. Easy, right? That’s what we thought too until we ran into corrupted logs, security reports pointing out race conditions, and unexplained crashes in…
When we first started writing code in C, we felt really confused and frustrated. Sometimes, a loop would never stop running, or a number would suddenly turn into a strange negative value. It’s a rite of passage and a warning.…
During our first few months working on a C project for tiny computers, our team ran into a problem that looked pretty simple. Our debug messages just would not print out right. We thought it was a small mistake. But…
