The tool is particularly useful for learning and small-scale applications. For production systems, consider using established libraries like OpenSSL for key generation to ensure compliance with security standards.

Purpose of the RSA Key Generator

The primary purpose of the RSA Key Generator is to provide a user-friendly, reliable tool for creating RSA key pairs based on established cryptographic principles. By automating the complex process of generating large prime numbers and computing modular inverses, the tool makes RSA cryptography accessible to a wide audience. It serves as both an educational resource for learning about public-key cryptography and a practical utility for generating keys for small-scale or experimental applications.

The tool promotes understanding of cryptographic concepts by demonstrating how key pairs are created and used. It also ensures that generated keys adhere to the mathematical foundations of the RSA algorithm, providing trustworthy results for users.

Scientific Basis of the Calculator

The RSA Key Generator is based on the RSA cryptosystem, a public-key encryption algorithm that relies on the mathematical properties of large prime numbers. The key generation process involves the following steps:

1. Generate Two Prime Numbers: Two large, distinct prime numbers p and q are randomly selected.
2. Compute Modulus: Calculate n = p * q, which serves as the modulus for both public and private keys.
3. Compute Euler’s Totient: Calculate φ(n) = (p-1) * (q-1), the number of integers coprime to n.
4. Select Public Exponent: Choose a public exponent e (commonly 65537) that is coprime to φ(n).
5. Compute Private Exponent: Calculate the private exponent d such that d * e ≡ 1 (mod φ(n)), using the extended Euclidean algorithm.

The public key is (n, e), and the private key is (n, d). The security of RSA relies on the difficulty of factoring n into p and q. This tool implements these steps using JavaScript, ensuring accurate and secure key generation for educational purposes. For more details, see RSA Key.

Applications in Real-World Scenarios

The RSA Key Generator has diverse applications across various domains:

• Cybersecurity Education: Teachers and students can use the tool to explore RSA cryptography and understand key generation.
• Secure Data Transfer: Developers can generate keys for encrypting data in small-scale applications or prototypes.

While the tool is suitable for educational and experimental use, production systems should use more robust libraries to ensure compliance with security standards.

Limitations and Considerations

The RSA Key Generator has certain limitations:

• Educational Use: The tool is designed for learning and small-scale applications, not for production-grade cryptography.
• Key Size Limitations: Due to browser performance constraints, the tool supports key sizes up to 2048 bits. Larger keys may cause performance issues.
• Randomness: JavaScript’s random number generation is not cryptographically secure. For real-world applications, use secure random number generators.

Users should avoid using keys generated by this tool for sensitive production systems. Instead, use established cryptographic libraries like OpenSSL or hardware security modules for critical applications.
