Cryptographic Hashing
Each session ID is processed using the highly secure SHA-512 hashing algorithm, a cryptographic technique that generates a unique, irreversible "fingerprint" for every session. This ensures that the session ID cannot be reverse-engineered or traced back to an individual, even with advanced computational methods.
To further enhance security, we add a secret value to the input during the hashing process. This secret acts as an additional layer of protection, making it virtually impossible to recreate or predict the session ID, even if an attacker knows other input details such as the client’s IP address or user agent.
How It Works
- Combining Inputs: We combine key session details (which shall not be named for security reasons) with a cryptographically secure secret value.
- SHA-512 Hashing: This combined input is hashed using SHA-512, producing a highly secure, anonymized session ID.
- Mathematically Irreversible: The resulting hash is cryptographically secure, ensuring it cannot be reverse-engineered or linked to specific user information.
Why This Matters
- Enhanced Privacy: Even if an attacker gains access to the hashed session ID, they cannot determine the original input due to the strength of SHA-512 and the added secret.
- Collision Resistance: SHA-512 ensures that every session ID is unique, minimizing the risk of collisions even for billions of sessions.
- Security by Design: The addition of a secret value ensures that the session ID is secure against brute force or dictionary attacks, providing robust protection against unauthorized access.
