Only the latest state of the main branch of cpp-prime-identifier is actively maintained.

cpp-prime-identifier is a beginner-friendly C++ algorithm project. It does not handle user authentication, network connections, or sensitive data. As such, its security surface is minimal — however, the following considerations still apply.

If you discover a security issue (e.g. a crash caused by malicious input, undefined behavior, or an integer overflow), please do not open a public issue.

Instead, contact the maintainer privately:

• Reach out to @achille010 directly via GitHub.
• Describe the issue, how to reproduce it, and the potential impact.

You can expect an acknowledgment within 7 days.

Even in a small algorithm project, good C++ practices matter:

• Integer overflow — be cautious when checking primality for very large numbers; use appropriate data types (e.g. long long).
• Unbounded input — if the program accepts user input, validate it to avoid unexpected behavior (e.g. negative numbers or non-integer input passed to prime-checking functions).
• Vector bounds — always ensure vector indexing stays within bounds to avoid undefined behavior.
• Compiler warnings — compile with -Wall -Wextra to catch potential issues early:

  g++ -Wall -Wextra -o prime main.cpp

We appreciate responsible handling of any findings. Thank you for helping keep this project safe.
