About:
SafeInt is a C++ class library designed to prevent integer overflow and underflow errors by throwing exceptions on undefined behavior. It provides a secure wrapper around primitive integer types, ensuring safe arithmetic operations without the performance overhead of bounds checking on every operation. This library is ideal for developers writing robust, security-critical code.
Key Features:
  • Exception-based error handling for overflow events
  • Minimal performance overhead compared to raw integers
  • Supports signed and unsigned integer types
  • Header-only library for easy integration
Use Cases:
  • Securing financial transaction calculations
  • Preventing vulnerabilities in low-level system code
  • Validating user input in high-reliability applications
Alternatives:
  • Boost.SafeNumerics – Boost provides similar functionality but requires the heavy Boost dependency, whereas SafeInt is a lightweight, standalone header.
